I am creating a web page that contains one Dropdownlist and Gridview.
Query is Dropdownlist will contains SQL Server database table list. When I select a table name from dropdownlist the Gridview needs to show entire table data and able to perform edit, update, delete, cancel action.
When I click edit Gridview need to show update and cancel buttons and it update should update dropdownlist table and also delete.
My code looks this:

Please any one can help.
Thanks in advance.
Given the above, I'd create a database table with two fields: tablename and columnname. There will be 4 rows with tablename = emp and each row will have a columnname = one of the columns from the emp table. Similarly, there will be 6 rows where tablename = dept and each row will have a columnname = one of the columns from the dept table. Then, in your GridView1_RowUpdating event, you can pull the names of the columns from the database based on the table that's been chosen in the DropDownList and update accordingly using whatever stored procedure you have in place for that table. In GridView1_RowCancelingEdit, you just need to do
GridView1.EditIndex = -1;
and rebind your data (you'll need a method for that) you're done.

I am working on a project in which I am to display, insert, delete the data in my access database. I made buttons that will display a specific table from the database. I then made an asp column to display the delete button next to each row. The issue that I am trying to figure out is: How can I have it so that when the delete button is clicked the specific row is identified so then I may delete it? Any hints or tips are welcomed. Thank you.

Many possibilites, my prefer is, bind a commandArgument in button with your identifier, and recover this value on post back
protected void btn1_Click(object sender, EventArgs e)
{
var identifier = ((Button)sender).CommandArgument;
}
Html
<ItemTemplate>
<asp:Button ID="btn1" Text="Delete" runat="server" OnClick="btn1_Click" CommandArgument='<%# Eval("PropertyName") %>'/>

I'm trying to generate a GridView and fill it by DropDownList SelectedValue
I have a DropDownList bind to Country data table and GridView bind to State data table and by changing the value of the DropDownList the data in the GridView change too
i'v tried this code:
this to fill the dropdownlist:
protected void FillDropdownList()
{
SqlCommand cmd = new SqlCommand();
SqlDataAdapter adp = new SqlDataAdapter();
DataTable dt = new DataTable();
try
{
cmd = new SqlCommand("Select * from Country", con);
adp.SelectCommand = cmd;
adp.Fill(dt);
DropDownListCountry.DataSource = dt;
DropDownListCountry.DataTextField = "CountryName";
DropDownListCountry.DataValueField = "CountryID";
DropDownListCountry.DataBind();
//DropDownListCountry.Items.Insert(0, "-- Select --");
//OR ddlEmpRecord.Items.Insert(0, new ListItem("Select Emp Id", "-1"));
}
catch (Exception ex)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "Message", "alert('Error occured : " + ex.Message.ToString() + "');", true);
}
finally
{
cmd.Dispose();
adp.Dispose();
dt.Clear();
dt.Dispose();
}
}
and this to generate the gridView
protected void BindGrid()
{
con.Open();
SqlCommand com = new SqlCommand("select * from State where CountryID='" + DropDownListCountry.SelectedValue + "'", con);
SqlDataAdapter sda = new SqlDataAdapter(com);
DataTable dt = new DataTable();
sda.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
con.Close();
}
and finally that's where i'm calling the functions:
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
FillDropdownList();
}
}
protected void DropDownListCountry_SelectedIndexChanged(object sender, EventArgs e)
{
BindGrid();
}
the .aspx file:
<asp:DropDownList ID="DropDownListCountry" runat="server" DataTextField="CountryName" DataValueField="CountryID" OnSelectedIndexChanged="DropDownListCountry_SelectedIndexChanged" >
</asp:DropDownList>
<br />
<!-- SqldataSource and GridView and Formview for State -->
<br />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="State Id" DataField="StateID" />
<asp:BoundField HeaderText="State Name" DataField="StateName" />
<asp:BoundField HeaderText="Country Id" DataField="CountryID" />
</Columns>
</asp:GridView>
but the code is not working and when i'm changing the value of DropDownList the GridView is not changing
For your Dropdownlist set AutoPostBack = true
I have a richtextbox and a gridview.
When I enter the data into the richtextbox, it should be displayed in a gridview and saved in database.
Now my requirement is that, if i am entering a paragraph or a large amount of data I should display a "readmore" button, that when clicked, display the complete data.

When someone selects a value in the DropDownList and hits the button, it will display the lists of doctors available in the province, city and per particular schedule.
Check this sample. I have used SQLDatasource with SelectParameters for this example (you
can replace it with your own object datasource, custom binding etc.) SQLDataSource Select Parameters
The second dropdownlist automatically populates when the first dropdownlist is changed
On Button even I am just selecting the currently selected values of each dropdownlist (You can select your doctor list in the same way)

You can drop a gridview on form like Abel said & on your button click event, fetch each drop down list selected value & execute your query & databaind your gridview like you are already doing with your drop down lists.
All you essentially need to do is to place the controls in the ASPX page declaratively:
<asp:DropDownList id="ddlSche" runat="server" />
You can calculate the results in the Page_Load using ddlSched.SelectedValue and similar methods.
Essentially, you use the button's onclick handler for this type of thing:. But since you already have a SelectedIndexChanged event, it seems that you're on the right track. It's fired when the user postbacks the page and the index was changed (or, in other words, the user selected something else than the current selection in the DropDownList).
How do I make an autocomplete TextBox in C# that binds to a data source?
You can use either jQuery Autocomplete or ASP.NET AJAX Toolkit Autocomplete
I use ajaxcontrol toolkit's AutoComplete
Try this:
.aspx page
<td>
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
<asp:AutoCompleteExtender ServiceMethod="GetCompletionList" MinimumPrefixLength="1"
CompletionInterval="10" EnableCaching="false" CompletionSetCount="1" TargetControlID="TextBox1"
ID="AutoCompleteExtender1" runat="server" FirstRowSelected="false">
</asp:AutoCompleteExtender>
Now To auto populate from database :
public static List<string> GetCompletionList(string prefixText, int count)
{
return AutoFillProducts(prefixText);
}
private static List<string> AutoFillProducts(string prefixText)
{
using (SqlConnection con = new SqlConnection())
{
con.ConnectionString = ConfigurationManager.ConnectionStrings["Conn"].ConnectionString;
using (SqlCommand com = new SqlCommand())
{
com.CommandText = "select ProductName from ProdcutMaster where " + "ProductName like #Search + '%'";
com.Parameters.AddWithValue("#Search", prefixText);
com.Connection = con;
con.Open();
List<string> countryNames = new List<string>();
using (SqlDataReader sdr = com.ExecuteReader())
{
while (sdr.Read())
{
countryNames.Add(sdr["ProductName"].ToString());
}
}
con.Close();
return countryNames;
}
}
}
Now:create a stored Procedure that fetches the Product details depending on the selected product from the Auto Complete Text Box.
Create Procedure GetProductDet
(
#ProductName varchar(50)
)
as
begin
Select BrandName,warranty,Price from ProdcutMaster where ProductName=#ProductName
End
Create a function name to get product details ::
private void GetProductMasterDet(string ProductName)
{
connection();
com = new SqlCommand("GetProductDet", con);
com.CommandType = CommandType.StoredProcedure;
com.Parameters.AddWithValue("#ProductName", ProductName);
SqlDataAdapter da = new SqlDataAdapter(com);
DataSet ds=new DataSet();
da.Fill(ds);
DataTable dt = ds.Tables[0];
con.Close();
//Binding TextBox From dataTable
txtbrandName.Text =dt.Rows[0]["BrandName"].ToString();
txtwarranty.Text = dt.Rows[0]["warranty"].ToString();
txtPrice.Text = dt.Rows[0]["Price"].ToString();
}
Auto post back should be true
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
Now, Just call this function
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
//calling method and Passing Values
GetProductMasterDet(TextBox1.Text);
}
1-Install AjaxControl Toolkit easily by Nugget
PM> Install-Package AjaxControlToolkit
2-then in markup
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<asp:TextBox ID="txtMovie" runat="server"></asp:TextBox>
<asp:AutoCompleteExtender ID="AutoCompleteExtender1" TargetControlID="txtMovie"
runat="server" />
3- in code-behind : to get the suggestions
[System.Web.Services.WebMethodAttribute(),System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefixText, int count, string contextKey) {
// Create array of movies
string[] movies = {"Star Wars", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II"};
// Return matching movies
return (from m in movies where m.StartsWith(prefixText,StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();
