How to display 10 recent news from database using Bootstrap?

I wanted to display 10 recent news from database. I have used LIMIT 10 in sql query to display 10 recent news. I am using bootstrap.
I am getting only 1 news from the database. I know that here I have to use datalist or listview in design. But I don't know how to implement it using Bootstrap.
Default.aspx:
<div class="container">
<h1 class="main-module-title">Recent <span>News</span></h1>
<%-- <asp:datalist runat="server">
<ItemTemplate>--%>
<div class="row-fluid">
<div class="row">
<div class="col-xs-12 col-sm-3 col-md-3">
<a href="#">
<asp:Image runat="server" ID="ImgNews" class="img-responsive img-box img-thumbnail"/>
</a>
</div>
<div class="col-xs-12 col-sm-9 col-md-9">
<h4><asp:Label ID="newsheader" runat="server" Text=""></asp:Label></h4>
<p runat="server" style="text-align:justify" id="newscontent"> </p>
</div>
</div>
<hr/>
</div>
<%-- </ItemTemplate>
</asp:datalist>--%>
</div>
Default.aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
MySqlConnection conn = null;
string newsitem = null;
if (!(Request.QueryString["newstitle"] == null))
{
Page.Header.Title = Request.QueryString["newstitle"] + " - DubaiExporters ";
}
else
{
Page.Header.Title = "DubaiExporters - Dubai Business News - UAE Exports";
}
try
{
string connStr = ConfigurationManager.ConnectionStrings["mysqldbeConnectionString"].ToString();
string newssql = null;
newssql = "SELECT * FROM news WHERE status = b'1' AND linkstatus = b'1' ORDER BY datepublished DESC LIMIT 10";
conn = new MySqlConnection(connStr);
MySqlCommand cmd = new MySqlCommand(newssql, conn);
conn.Open();
MySqlDataReader r = cmd.ExecuteReader(CommandBehavior.CloseConnection);
if(r.Read())//while(r.Read())
{
newsheader.Text = HttpUtility.HtmlDecode(r["newstitle"].ToString().Trim()).ToString();
newscontent.InnerHtml = HttpUtility.HtmlDecode(r["newsbrief"].ToString().Trim()).ToString();
ImgNews.ImageUrl = "~/images/newspictures/" + r["image"].ToString();
}
}
catch (MySqlException ex)
{
}
catch (Exception ex)
{
}
finally
{
if (conn != null)
{
conn.Close();
}
}
}
}

try the below template and bind the DataList to DataSource in the Page Load event inside !Page.IsPOstBack condition

How o bind data like this... <ul><li>binded data</li></ul>

I need to bind some data from a stored procedure into ul elements to display them as contents of a list. I am not able to do it. Please help me. The code I am using is:
(ASPX)HTML code
<div class="form-group">
<asp:label runat="server" class="control-label col-sm-3 col-md-3 col-lg-3" ID="LblInventoryNumber" Text="Inventory Number"></asp:label>
<div class="col-sm-9">
<div class="input-group">
<asp:TextBox runat="server" class="form-control" id="TxtInventoryNumber" placeholder="Number" ></asp:TextBox>
<span class="input-group-addon">
<a href="javascript:;" class="dropdown-toggle" data-toggle="dropdown" ><img src="images/icon-add-on-1.png" alt="" /></a>
<ul class="dropdown-menu dropdown-menu-right" id="ul" runat="server">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
</ul>
</span>
</div>
</div>
</div>
In place, the C# code is:
SqlConnection con = new SqlConnection(ConString);
string com = "Select SiteID from IC_INVENTORY_T ";
SqlDataAdapter adpt = new SqlDataAdapter(com, con);
DataTable dt = new DataTable();
adpt.Fill(dt);
ul.DataSource = dt;
ul .DataBind();
ul.DataTextField = "SiteID";
ul.DataValueField = "SiteID";
ul.DataBind();
Please help me on this...

Where as your question is totally not clear, still if you are using datatable to keep the data after execution, you can use source binding . e.g-->
Code Sample
<ul>
<%
for(int I=0; I< dt.rows.count;i++)
{%>
<li><%dt.rows[i][column_name].ToString()%></li>
<li><%dt.rows[i][column_name].ToString()%></li>
<%}%>
</ul>
In this way you can show somewhat.... But be clear

Try using foreach
foreach item in com
{
<li>item.coloumname</li>
}
hope it's help and... many source to do this and keep practice

Asp.Net SQL Delete Statement

I have an Asp.net application and I am trying to delete a row from my 'Users' db if the user submits the requests via the web but I can't seem to get it to work.
HTML
<div class="panel panel-danger">
<div class="panel-heading">
<h3 class="panel-title">Remove User</h3>
</div>
<div class="panel-body">
<asp:Label ID="lbRemoveUser" runat="server" Text="Remove User">
<b>Enter Full Name</b>
</asp:Label>
<asp:TextBox runat="server" ID="txtRemoveUser" CssClass="form-control" AutoPostBack="true" OnTextChanged="txtRemoveUser_TextChanged" />
<asp:Label ID="removeUserNotExist" runat="server" Text="The user entered does not exist." Visible="false" style="color: red"></asp:Label>
</div>
<div class="panel-footer">
<div class="text-center">
<asp:Button CssClass="btn btn-danger" ID="btnSubmitRemoveUser" runat="server" Text="Remove User" ToolTip="Click to remove the user from the list." OnClick="removeUserSubmitButton_Click" />
</div>
</div>
</div>
<!-- Confirm Removal Modal-->
<div class="modal fade" id="confirmRemoveUserModal">
<div class="modal-dialog" style="margin-top: 55px">
<div class="modal-content">
<div class="modal-header ConfirmHeader">
<h4 class="modal-title" id="myModalLabel">Confirm Removal</h4>
</div>
<div class="modal-body">
<p>Are you sure you want to remove <b><%=Session["txtRemoveUser"] %></b> from the payday lunch list?</p>
<p>If you don't, click 'No' and the user will not be removed.</p>
</div>
<div class="modal-footer ConfirmFooter">
<asp:Button id="btnRemoveConfirmYes" runat="server" CssClass="btn btn-success" Text="Yes" OnClick="btnRemoveConfirmYes_Click" ToolTip="Click to remove the user from the payday lunch list." />
<asp:Button id="btnRemoveConfirmNo" runat="server" CssClass="btn btn-warning" Text="No" OnClick="btnAllCloses_Click" ToolTip="Click to close this screen. The user will not be removed." />
</div>
</div>
</div>
</div>
Code I tried
public void btnRemoveConfirmYes_Click(object sender, EventArgs e)
{
string connection = ConfigurationManager.ConnectionStrings["PaydayLunchConnectionString1"].ConnectionString;
SqlConnection conn = new SqlConnection(connection);
conn.Open();
SqlCommand cmd1 = new SqlCommand("DELETE FROM Users WHERE Name = " + txtRemoveUser.Text, conn);
conn.Close();
txtRemoveUser.Text = "";
Response.Redirect("/AdminSide/TaskList.aspx");
}
Like I said all I want is to delete the entry if it exists in my db. I already have a check to make sure that the entry exists in the 'Users' table
Do I need the SqlDataReader rd1 = cmd1.ExecuteReader(); as when I tried it, I got a server error "System.Data.SqlClient.SqlException: Invalid column name 'Test2'."

You are not using ExecuteNonQuery. You also have to wrap the user-name in apostrophes:
SqlCommand cmd1 = new SqlCommand("DELETE FROM Users WHERE Name = '" + txtRemoveUser.Text + "'", conn);
But you should always use sql parameters to prevent sql injection and other issues:
using(var cmd1 = new SqlCommand("DELETE FROM Users WHERE Name = #Name", conn))
{
cmd1.Parameters.Add("#Name", SqlDbType.VarChar).Value = txtRemoveUser.Text;
conn.Open();
cmd1.ExecuteNonQuery();
}
also use the using-statement on types that implement IDisposable like SqlCommand or -more important- SqlConnection to ensure that unmanaged resources are disposed.

Show product details in page

I need to show products details in a page.
My aspx is like below...
<div class="col-xs-12 col-sm-4 no-margin product-item-holder hover"> <!-- this div will be repeated for each product -->
<div class="product-item">
<div class="image">
<img runat="server" id="img" alt="" src="" />
</div>
<div class="body">
<div class="label-discount clear"></div>
<div class="title">
<a runat="server" id="name" href="single-product.html"></a>
</div>
</div>
<div class="prices">
<div class="price-prev"></div>
<div runat="server" id="price" class="price-current pull-right"></div>
</div>
<div class="hover-area">
<div class="add-cart-button">
Enquiry
</div>
</div>
</div>
and my codebehind is like below...
dbConnection cn = new dbConnection();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
getLoopData();
}
}
public void getLoopData()
{
cn.con.Open();
cn.cmd.Connection = cn.con;
cn.cmd.CommandText = "select * FROM products";
MySqlDataReader reader = cn.cmd.ExecuteReader();
while (reader.Read())
{
//int id = reader.GetInt32(0);
name.InnerText = reader["InventionName"].ToString();
price.InnerText = reader["Price"].ToString();
img.Src = reader["Picture"].ToString();
}
reader.Close();
cn.con.Close();
}
But it is showing only last product details.
How should I repeat the div for each product and how to show every products in page ??

You can use Asp Repeater to do that.
Check this link out : http://www.w3schools.com/aspnet/aspnet_repeater.asp

You need a datagrid control, repeater or similar to show tabular data.
Right now you only have one control per attribute to show all records, that's why last one wins.

Your view/page could be like this:
<asp:Repeater ID="ProductRepeater" runat="server" EnableViewState="False">
<ItemTemplate>
<div class="product-item">
<div class="image">
<img id="img" alt="" src='<%# Eval("Picture") %>' />
///...
</ItemTemplate>
</asp:Repeater>
In your code you could do this:
cn.con.Open();
cn.cmd.Connection = cn.con;
cn.cmd.CommandText = "SELECT InventionName, Price, Picture FROM products";
MySqlDataReader reader = cn.cmd.ExecuteReader();
ProductRepeater.DataSource = reader;
ProductRepeater.DataBind();

You are iterating a list, and assigning data to name, price and img.Src, but you overwrite the values on each iteration, therefore you only have the values from the last element.
You should bind you data source (reader) to an <asp:Repeater>'s DataSource property. In your markup you specify a header (HeaderTemplate), a footer (FooterTemplate) and content (ItemTemplate). You can omit the header and footer template if you don't need them. You can also use an AlternatingItemTemplate if you need to do different things with odd/even rows (e.g. alternating row color in a table).
You can access properties of the databound datatype using the <%# Eval("SomeProperty") %> which is a databinding expression.
HTML markup would be something like this:
<asp:Repeater id="Products" runat="server">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<div class="col-xs-12 col-sm-4 no-margin product-item-holder hover"> <!-- this div will be repeated for each product -->
<div class="product-item">
<div class="image">
<img class="img" alt="" src="<%# Eval("Picture") %>" />
</div>
<div class="body">
<div class="label-discount clear"></div>
<div class="title">
<a class="name" href="single-product.html"><%# Eval("InventionName") %></a>
</div>
</div>
<div class="prices">
<div class="price-prev"></div>
<div class="price" class="price-current pull-right"><%# Eval("Price") %></div>
</div>
<div class="hover-area">
<div class="add-cart-button">
Enquiry
</div>
</div>
</div>
</div>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:Repeater>
and wire up the datasource in codebehind like this:
cn.con.Open();
cn.cmd.Connection = cn.con;
cn.cmd.CommandText = "select * FROM products";
MySqlDataReader reader = cn.cmd.ExecuteReader();
Products.DataSource = reader; // rather than iterating manually, you assign the datasource to the repeater.
Products.DataBind();
reader.Close();
cn.con.Close();
Side note: I changed the attribute from id to class on the name, price and img element. Because when this markup is rendered it would have been with multiple elements with the same id, which it shouldn't since id is supposed to be unique according to specification.

Multiple bootstrap sliders using asp:repeater control

I have to use multiple bootstrap carousel in single page, using the asp repeater control but it doesn't work, it just show one slider on the page
Here is the html and asp code
<div class="col-md-12">
<div id="Carousel" class="carousel slide">
<!-- Carousel items -->
<div class="carousel-inner">
<div class="item">
<div class="row">
<asp:Repeater runat="server" ID="Slider1">
<ItemTemplate>
<div class="col-md-2">
<div class="row">
<a target="_blank" href="<%# Eval("URL") %>">
<img class="caption" src="../Includes/gaceta/<%# Eval("Titulo") %>/files/res/pages/page_0000.jpg" alt="<%# Eval("Titulo") %>" width="188" height="222" /></a>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
</div>
<!--.row-->
</div>
</div>
<!--.carousel-inner-->
<a data-slide="prev" href="#Carousel" class="left carousel-control">‹</a>
<a data-slide="next" href="#Carousel" class="right carousel-control">›</a>
</div>
<!--.Carousel-->
</div>
<hr />
<div class="col-md-12">
<div id="Carousel2" class="carousel slide">
<!-- Carousel items -->
<div class="carousel-inner">
<div class="item">
<div class="row">
<asp:Repeater runat="server" ID="Slider2">
<ItemTemplate>
<div class="col-md-2">
<div class="row">
<a target="_blank" href="<%# Eval("URL") %>">
<img class="caption" src="../Includes/gaceta/<%# Eval("Titulo") %>/files/res/pages/page_0000.jpg" alt="<%# Eval("Titulo") %>" width="188" height="222" /></a>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
</div>
<!--.row-->
</div>
</div>
<!--.carousel-inner-->
<a data-slide="prev" href="#Folletos" class="left carousel-control">‹</a>
<a data-slide="next" href="#Folletos" class="right carousel-control">›</a>
</div>
<!--.Carousel-->
the javascript
$(document).ready(function () {
$('#Carousel').carousel('pause');
$('#Carousel2').carousel('pause');
$("div.item:first").addClass("active");
});
and the methods to bind the repeater
protected void Page_Load(object sender, EventArgs e)
{
BindSlider1(5);
BindSlider2(1);
}
protected void BindSlider1(int Ubicacion)
{
using (SqlConnection con = Conexion.Conecta())
{
using (SqlCommand cmd = new SqlCommand("SelGacetaUbicacion", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#UBICACION", SqlDbType.Int).Value = Ubicacion;
con.Open();
Slider1.DataSource = cmd.ExecuteReader();
Slider1.DataBind();
}
}
}
protected void BindSlider2(int Ubicacion)
{
using (SqlConnection con = Conexion.Conecta())
{
using (SqlCommand cmd = new SqlCommand("SelGacetaUbicacion", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#UBICACION", SqlDbType.Int).Value = Ubicacion;
con.Open();
Slider2.DataSource = cmd.ExecuteReader();
Slider2.DataBind();
}
}
}

I tried your code, and found this issues:
1- Review how to build the carousel markup depending on which version of bootstrap you are using. I tried with Bootstrap v3.1.0 and had to change parts of your markup. Refer to documentation or this sample.
For instance, <div class="item"> should be placed inside your repeater, and should have a <div class="container"> immediatly inside of it.
2- You are not initializing correctly both carousels from jquery, do something like this to correct it:
$("#Carousel div.item:first").addClass("active");
$("#Carousel2 div.item:first").addClass("active");
