Hi Heba,

Please take a look at the sample code snippet, you can try a similar approach.

C#:

//Image Button Click
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
  ImageButton img = (ImageButton)sender;
  GridDataItem item = (GridDataItem)img.NamingContainer;
  string id = item.GetDataKeyValue("ID").ToString();  // Access the selected row ID
}

//To open a new Tab
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
  {
    GridDataItem item = (GridDataItem)e.Item;
    ImageButton imgbtn = (ImageButton)item.FindControl("ImageButton1");
    imgbtn.Attributes.Add("onclick", "document.forms[0].target= '_new';return true;"); // Open a newtab
  }
}

Thanks,
