GridImageColumn to dispay image only when the flag is set

[Karthi]

I have a requirement that I need to dispay an image if the flag is false and should not display anything (the cell must be empty) if the flag is true. How to achieve this using GridImageColumn?

Thanks in advance..

Hello Karthi,

You can check the value of flag from code behind and set the image url from there. Sample code is given below.

ASPX:

<telerik:GridImageColumn  UniqueName="GridImageColumn" />

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
       if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            TableCell flag = (TableCell)item["flag"];
            if (flag.Text == "true")
            {
                Image img = (Image)item["GridImageColumn"].Controls[0];
                img.ImageUrl = "~/Images/btnSave.gif";//set image url
            }
            else
            {
                TableCell cell = (TableCell)item["GridImageColumn"];
                cell.Text = " ";//clears image column
            }
        }
    }
