Can you explain it clearer?

c_4less 26-Mar-15 20:58pm

I have the column name stored in codebehind c# variable. I want to mark the value in aspx code.

ex: string mycolumn="something";
I want this mycolumn variable in aspx (Text='<%# Bind("HoursSpent") %>') code. so the value of mycolumn variable will act as a column in gridview

Solution 2

XML

In your markup you can do this:

<%# VariableName %>

So, the variable value (Ex:columnDay=Day1 ) Day1 column will get displayed in Gridview??????

Solution 1

C#

protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
         decimal mycolumn= 7.50; //i believe hours value should be decimal or int
         TextBox txtHrsSpentColumn = (TextBox)e.Row.FindControl("TxtHoursSpent");
         txtHrsSpentColumn.Text = mycolumn.ToString(); 
     }
}

Please check if this is what you need.
if the value of mycolumn variable is coming from a control change it to

C#

decimal mycolumn = Convert.ToDecimal(TextBox.Text);

I've a codebehind lik below

qry.ViewFields = <fieldref name="ID"><fieldref name="RequestID"><fieldref name="Title"><fieldref name="" + columnDay + "">;

in this query, columnDay holds some value which is a column in gridview.
I want to bind this "columnDay" in aspx file also. so i can view the column based on the variable value

<itemtemplate>
<asp:TextBox ID="TxtHoursSpent" Text='<%# Bind("HoursSpent") %>' runat="server" MaxLength="4" Width="25" >

int columnday=calendar1.selectedValue.Day
qry.ViewFields =
"select Id,Title,"+columnday+"from Timesheet";
I'm displaying 3 fields: ID, Title,Day (where day is passed using variable called columnday) I can able to put this values in aspx as
1. Text='<%# Bind("ID") %> for Id
2. Text='<%# Bind("Title") %> for Title
3. Text='<%# Bind("???") %> for Days.. How can i display it in grid aspx???

bjay tiamsic 27-Mar-15 2:11am

select Id,Title,DATENAME(DW,CAST('"+columnday+"' AS INT)) as Day_ from Timesheet
Text='<%# Bind("Day_") %>

bjay tiamsic 27-Mar-15 2:13am

This is applicable if you want to display DayName (i.e. Monday, Tuesday, etc) in you grid. But if you want to display only the number representation of the day make it
select Id,Title,'"+columnday+"' as Day_ from Timesheet
Text='<%# Bind("Day_") %>

use the word "AS" to name your column
