Cell Text Always &nbsp:

I want to display the text of a specific cell in a textbox whenever I select a row from my gridview but whenever i do this "&nbsp" is the only text that I get even though the cell is not empty. Data on the gridview is bound from my database and I made a function where all the data from my database will be bound on my gridview. Below is the code that I'm using.
textbox1.Text = myGridView.SelectedRow.Cells[3].Text;

Function that binds Data
private void PopulateData()
{
DataTable dataTable = new DataTable();
using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["TestCS"].ConnectionString))
{
string path = "PopulateSQL.txt";
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(path))
{
while (sr.Peek() >= 0)
{
sb.Append(sr.ReadLine());
}
string sql = sb.ToString();
using (SqlCommand cmd = new SqlCommand(sql, connection))
{
using (SqlDataAdapter dataAdapt = new SqlDataAdapter(cmd))
{
dataAdapt.Fill(dataTable);
ViewState["NormalGrid"] = dataTable;
}
}
}
}
if (dataTable.Rows.Count > 0)
{
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
}
else
{
//Displays 'No Data Found' to gridview if there are no data in table
dataTable.Rows.Add(dataTable.NewRow());
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
TraineeGrid.Rows[0].Cells.Clear();
TraineeGrid.Rows[0].Cells.Add(new TableCell());
TraineeGrid.Rows[0].Cells[0].ColumnSpan = dataTable.Columns.Count;
TraineeGrid.Rows[0].Cells[0].Text = "No Data Found";
TraineeGrid.Rows[0].Cells[0].HorizontalAlign = HorizontalAlign.Center;
}
}

You can use this: textbox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
In OnSelectedIndexChanged :
protected void OnSelectedIndexChanged1(object sender, EventArgs e)
{
//Get the selected row
GridViewRow row = GridView1.SelectedRow;
if (row != null)
{
// With
// TextBox1.Text = (row.FindControl("lblLocalTime") as Label).Text;
// Without
TextBox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
}
}

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"

<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
<asp:BoundField DataField="City" HeaderText="City" ItemStyle-Width="150" />
</Columns>

I've already found a solution. The problem is Im using TemplateField instead of BoundField that's why I cant use .Cells[] to get the specific cell that I wanted to get. However, if you are using TemplateField you can use .FindControl() and put in the ID of the label where your binding of data happens (ex. Text ='<%# Eval("FirstName") %>'). You can see that I put label on ItemTemplate to call it's ID.

Unable to bind multiple dropdownlist in gridview on editing a row

I've two columns Customer Type and File Frequency in the gridview. When the grid is in normal mode I show the values using label. On editing the row, those two columns become dropdowns. I bind the dropdowns using OnRowDataBound="RowDataBound". But, Only first dropdown(whichever first written in the method) in the RowDataBound method getting bind on the edit mode.
.aspx
<asp:GridView ID="gvManageCustomers" DataKeyNames="Ship_To" runat="server" AutoGenerateColumns="False"

da.Fill(dt);
return dt;
}

{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
DropDownList ddlgvFileFreq = (DropDownList)e.Row.FindControl("ddlgvFileFreq"); //getting binded
ddlgvFileFreq.DataSource = FetchFileFrequency();
ddlgvFileFreq.DataTextField = "FileFrequency";

}
}
}
catch (Exception ex)
{
//log error
errorlog.WriteErrorLog(ex.ToString());
}
}

The problem is in this line, it trows an exeption. That's why only the topmost binding would work.
ddlgvFileFreq.Items.FindByValue((e.Row.FindControl("lblFileFreq") as Label).Text).Selected = true;
But it looks like you want the DropDownList to have the correct SelectedValue. This is how you can do that.
DataRowView row = e.Row.DataItem as DataRowView;
DropDownList ddlgvFileFreq = (DropDownList)e.Row.FindControl("ddlgvFileFreq");
ddlgvFileFreq.DataSource = FetchFileFrequency();
ddlgvFileFreq.DataTextField = "FileFrequency";
ddlgvFileFreq.DataValueField = "FileFrequency_ID";
ddlgvFileFreq.DataBind();
try
{
ddlgvFileFreq.SelectedValue = row["FileFrequency_ID"].ToString();
}
catch
{
}
DropDownList ddlgvCustomerType = (DropDownList)e.Row.FindControl("ddlgvCustomerType");
ddlgvCustomerType.DataSource = FetchCustomerType();
ddlgvCustomerType.DataTextField = "Customer_Type";
ddlgvCustomerType.DataValueField = "Customer_TypeID";
ddlgvCustomerType.DataBind();
try
{
ddlgvCustomerType.SelectedValue = row["Customer_TypeID"].ToString();
}
catch
{
}

<asp:TemplateField HeaderText="Customer Type">

Why is my data not showing in my GridView? [duplicate]

This question already exists:
how to show data in gridview from arraylist in asp.net?
Closed 8 years ago.
I have a database where there is userid, problemname and status column. I am retrieving this data from database in an ArrayList and returning it. Now to show in GridView I have taken a DataTable and in the DataTable I have put three columns and I just want to show my data that is saved in the ArrayList in these columns by making one row.
Here is my code:
protected void Page_Load(object sender, EventArgs e)
{
ArrayList myArrayList = ConvertDataSetToArrayList();
// Display each item of ArrayList
DataTable dt = new DataTable();
dt.Columns.Add("User Id");
dt.Columns.Add("Problem Name");
dt.Columns.Add("Status");
foreach (Object row in myArrayList)
{
dt.Rows.Add();
dt.Rows[dt.Rows.Count - 1]["User Id"] = ((DataRow)row)["userid"].ToString();
dt.Rows[dt.Rows.Count - 1]["Problem Name"] = ((DataRow)row) ["problemname"].ToString();
dt.Rows[dt.Rows.Count - 1]["Status"] = ((DataRow)row)["status"].ToString();
}
GridView1.DataSource =dt;
GridView1.DataBind();
}
public ArrayList ConvertDataSetToArrayList()
{
string con = " ";
con = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
SqlConnection objsqlconn = new SqlConnection(con);
objsqlconn.Open();
SqlCommand cmd = new SqlCommand("SELECT userid,problemname,status FROM problemtable", objsqlconn);
cmd.ExecuteNonQuery();
cmd.CommandType = CommandType.Text;
SqlDataAdapter myAdapter = new SqlDataAdapter();
myAdapter.SelectCommand = cmd;
DataSet myDataSet = new DataSet();
myAdapter.Fill(myDataSet);
ArrayList myArrayList = new ArrayList();
foreach (DataRow dtRow in myDataSet.Tables[0].Rows)
{
myArrayList.Add(dtRow);
}
objsqlconn.Close();
return myArrayList;
}
Here is my html:
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" >
<Columns>
<asp:TemplateField HeaderText="cdd">
<ItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
</body>
Why is my data is not showing in my GridView?

You need to bind your data to specific controls in your gridview. For example, you need to have labels in your gridview itemtemplate to bind your data to. Here is an example:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" >
<Columns>
<asp:TemplateField HeaderText="cdd">
<ItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="User Id">
<ItemTemplate>
<asp:Label ID="lbl_userid" runat="server" Text='<%# Eval("User Id") %>' CssClass="lbl"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Problem Name">
<ItemTemplate>
<asp:Label ID="lbl_problemname" runat="server" Text='<%# Eval("Problem Name") %>' CssClass="lbl"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="status">
<ItemTemplate>
<asp:Label ID="lbl_status" runat="server" Text='<%# Eval("Status") %>' CssClass="lbl"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

I agree that an ArrayList is a poor choice, but, regardless of how you're binding the data, you need to tell the gridview what it's supposed to show. You can do this using inline tags or by using an onitemdatabound trigger. I recommend you look up some more examples of gridviews.

how to read xml with LINQ

I am trying to read XML with LINQ but I am having a problem. This is my first time using LINQ. I want to read the xml and create a datatable, then bind the datatable to gridview.
here is my xml
<?xml version="1.0" encoding="utf-8" ?>
<controls>
<control id="10001" turkce="türkçe1" english="english1" />
<control id="10002" turkce="türkçe2" english="english2" />
<control id="10003" turkce="türkçe3" english="english3" />
<control id="10004" turkce="türkçe4" english="english4" />
</controls>
here is my c# code
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Türkçe");
dt.Columns.Add("English");
//Load xml
XDocument xdoc = XDocument.Load("Language.xml");
//Run query
var lv1s = from lv1 in xdoc.Descendants("control")
select new
{
id = lv1.Attribute("id").Value,
turkce = lv1.Attribute("turkce").Value,
english = lv1.Attribute("english").Value
};
foreach (var lv1 in lv1s) {
dt.Rows.Add(lv1.id,lv1.turkce,lv1.english);
}
when I run the program, it doesnt do anything. The gridview is empty. what am I doing wrong?

DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Türkçe");
dt.Columns.Add("English");
//Load xml
XDocument xdoc = XDocument.Load("E:/MyApps/TestDemo/Language.xml");
//Run query
var lv1s = from lv1 in xdoc.Descendants("control")
select new
{
id = lv1.Attribute("id").Value,
turkce = lv1.Attribute("turkce").Value,
english = lv1.Attribute("english").Value
};
foreach (var lv1 in lv1s)
{
dt.Rows.Add(lv1.id, lv1.turkce, lv1.english);
}
gv.DataSource = dt;
gv.DataBind();
Please note that you need to use exact URL for loading your XML file which I have done above. And also you need to bind the data table to GridView.
Below is my GridView code:
<asp:GridView ID="gv" runat="server" AutoGenerateColumns="false" Width="300px">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:Label runat="server" ID="lblHeaderID" Text="ID"></asp:Label>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<% #Eval("ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
<asp:Label runat="server" ID="lblHeaderTürkçe" Text="Türkçe"></asp:Label>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lblTürkçe" runat="server" Text='<% #Eval("Türkçe") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
<asp:Label runat="server" ID="lblHeaderEnglish" Text="English"></asp:Label>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lblEnglish" runat="server" Text='<% #Eval("English") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
My grid view is displaying properly.

Deleting a record from Gridview with ObjectDataSource

I have a gridview that binds its rows from an objects method:
public DataSet GetObjects()
{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
var source = from p in CommentsList
select new { p.CommentID, p.Img, p.Name, p.Comment };
dt.Columns.Add("CommentsID");
dt.Columns.Add("Img");
dt.Columns.Add("Name");
dt.Columns.Add("Comment");
foreach (var item in source)
{
DataRow userDetailsRow=dt.NewRow();
userDetailsRow["Img"] = item.Img;
userDetailsRow["Name"] = item.Name;
DataRow commentsID = dt.NewRow();
userDetailsRow["CommentsID"] = item.CommentID;
DataRow comments = dt.NewRow();
userDetailsRow["Comment"] = item.Comment;
dt.Rows.Add(userDetailsRow);
//dt.Rows.Add(comments);
}
ds.Tables.Add(dt);
return ds;
}
My delete method. Should receive the commentsID to delete it from the database and then rebind the Gridview.. But how? do i pass the CommentsID from the gridview to this method
public void RemoveComment(int CommentsID)
{
}
GridViews Two templates:
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lblMessage" runat="server" Text='<%# Bind("Comment") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Image ID="imgName" runat="server" imageUrl='<%# Bind("Img") %>'></asp:Image><br />
<asp:Hyperlink ID="hyperLink" runat="server" Text='<%# Bind("Name") %>' ></asp:Hyperlink>
</ItemTemplate>
</asp:TemplateField>
</Columns>
Now, I want to delete a row, how do I do that? I know that DataKeyNames exist..but how do I set the commentsID as my dataKeyNames, and how do i delete a record?

You can specify the Delete method to the objectDataSource and it will be very simple...e.g.
<asp:ObjectDataSource ID="ods" runat="server" DeleteMethod="RemoveComment" SelectMethod="GetCityByStateID" TypeName="">
<DeleteParameters>
<asp:Parameter Name="CommentsID" Type="Int32" />
</DeleteParameters>
<SelectParameters>
</SelectParameters>
</asp:ObjectDataSource>
Whenever the Gridview Delete button is hit this will automatically fire this method and delete the record.
