Question

I have a Gridview and on rowDatabound i am creating on click on that row and
showing modal popup. what i want is when the row is clicked , the ID for that row should be passed.

protected void grdOrderProduct_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#ceedfc'");
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=''");
        e.Row.Attributes.Add("style", "cursor:pointer;");
        e.Row.Attributes["onClick"] = Page.ClientScript.GetPostBackClientHyperlink(btnPop, "12");
    }
}

How can i Get this “12” on my server control. i have put 12 as static for demo. but it will change.

To know which row was clicked, you have to use the Row property of the GridViewRowEventArgs

    protected void grdOrderProduct_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#ceedfc'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=''");
            e.Row.Attributes.Add("style", "cursor:pointer;");
            e.Row.Attributes["onClick"] = Page.ClientScript.GetPostBackClientHyperlink(btnPop, e.Row.RowIndex.ToString());

        }
    }

RowIndex would be passed as an argument to btnPop. In order to receive it btnPop should be implementing IPostBackEventHandler.

Like this:

public class MyControl : Button, IPostBackEventHandler
  {

    // Use the constructor to defined default label text.
    public MyControl()
    {
    }

    // Implement the RaisePostBackEvent method from the
    // IPostBackEventHandler interface. 
    public void RaisePostBackEvent(string eventArgument)
    {
      //You receive the row number here.
    }
  }
