Hi Andrés,

You can add the texbox in the ItemCreated event of the grid. It is fired for all items and the you can find the specific cell in which to add the textbox.

Find more information on accessing grid cells and rows in the below article:

Hi:

It's confuse for me.
I have the following code:

 

RadGrid MiRadGrid = new RadGrid();

 

 

 

TemplateColumn MiColumna = new TemplateColumn();

 

 

 

TextBox MiTextBox = new TextBox();

 

 

MiTextBox.ID =

"MiTextBox";

 

 

MiColumna.ItemTemplate = MiTextBox; //Error

 

MiRadGrid.Columns.Add(MiColumna);

It shows an error, and I don't know solve.

Thanks.

Hello,

Try the following snippet code. Hope it helps you.

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       if (e.Item is GridDataItem)
       {
           GridDataItem Item = (GridDataItem)e.Item;
           TableCell cell = Item["EmpId"];
           TextBox txtBox = new TextBox();
          txtBox.ID = "Txt1";
           cell.Controls.Add(txtBox);
        }
    }

Hello Princy,

I follow your code to create a dynamic textbox from the radgrid_ItemDataBound.  In my case, by default I set the display property to false.  How do I change the property display to true when user click on a different radgrid_SelectedIndexChanged?  Please see my code below:

 protected void scheduleRadGrid_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem note = (GridDataItem)e.Item;
            TableCell cell = note["Note"];
            RadTextBox txtBox = new RadTextBox();
            txtBox.ID = "txtNote";
            txtBox.Width = 500; //or Unit.Pixel(500)
            txtBox.MaxLength = 1000;
            txtBox.TextMode = InputMode.MultiLine;
            cell.Controls.Add(txtBox);
            txtBox.Display = false;
           
        }
    }
and I want to turn the textbox display = true from here:
  protected void doctorRadGrid_SelectedIndexChanged(object sender, EventArgs e)
    {
             foreach (GridDataItem gridItem in scheduleRadGrid.Items)
                    {
                        ((RadTextBox)gridItem.FindControl("txtNote")).Display = true;
                    }
}
but it's not working.  Please help!  thanks a lot!

Hello Han,

You should create the controls in ItemCreated event handler. Also check the following help documentation.

Thank you so much! :-)  It works now. You and your team have a good weekend.
