I am trying to inherit GridBoundColumn.

where i override preparecell method.

I am putting an ImageButton  in GridDataItem.

now i need to fire owner grid ItemCommand event on this ImageButton's  Click event.

How can i do that?

check out this code.

[ToolboxData("<{0}:ActiveDeactiveColumn runat=server></{0}:ActiveDeactiveColumn>")]
    public class ActiveDeactiveColumn : GridBoundColumn
    {
        public override void PrepareCell(TableCell cell, GridItem item)
        {
          
            if (item is GridHeaderItem)
            {
                Literal lt = new Literal();

                lt.Text = this.HeaderText;

                cell.Controls.Add(lt);
            }

            if (item is GridDataItem)
            {

                ImageButton imgBtn = new ImageButton();

                bool value = (Boolean)DataBinder.Eval(item.DataItem, this.DataField);

                String url = value ? "OSS.Resources.tick.gif" : "OSS.Resources.cross.gif";

                imgBtn.ImageUrl = this.Owner.OwnerGrid.Page.ClientScript.GetWebResourceUrl(this.GetType(), url);

                imgBtn.OnClientClick = "return confirm('Are you sure want to " + (value ? "deactivate" : "activate") + " this record?')";

                imgBtn.CommandName = value ? "deactivate" : "activate";

                //What should be written Here?
                //imgBtn.Click += ""???
               // how can i bind this.owner.ownerGrid.ItemCommand (RadGrid.ItemCommand) event to this ImageButton event?
               
                cell.Controls.Add(imgBtn);
 
            }   

        }
    }

Hello Sameer,

To achieve the desired functionality, I suggest that you use the FireCommandEvent(eventName, eventArgs) method of the corresponding GridDataItem in the Click event handler of the image button.
Your code could look like:
  void ImageButton_Click(object sender, ImageClickEventArgs e)
 {
      GridDataItem item = (sender
as GridDataItem).NamingContainer as GridDataItem;
      item.FireCommandEvent("CommandName", GridCommandEventArgs);
 }

For additional information, please take a look at the How to fire command events from code help topic.
