动态gridview-如何在rowdatabound中引用

Question

I am dynamically creating several gridviews depending on data in a DB. I generate the gridview as follows in a foreach statement:

GridView gdv = new GridView();
gdv.ID = "gdv" + i.ToString();
gdv.SelectedIndexChanged += new EventHandler(gdv_SelectedIndexChanged);
gdv.RowDataBound += gdv_RowDataBound; 

RowDataBound looks like the following:

protected void gdv_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   {             
      e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(((GridView)sender), "Select$" + e.Row.RowIndex);
   }
}

This all works as expected, however the ((GridView)sender) returns the following value:

'gdv00'

What i need returned for this link to work is the following:

'ctl00$ctl00$MainContent$Main$gdv0'

Pretty sure this has something to do with the master pages? but not sure how to reference this properly in the rowdatabound event?

Answer 1

The ID of ctl00$ctl00$MainContent$Main$gdv is the UniqueID property of the grid control (client ID is separated by _). This is the ID rendered to the browser. I think the problem here is that the control isn't added to the control tree immediately, which has been a problem for some in the past. Try doing it this way:

GridView gdv = new GridView();
gdv.ID = "gdv" + i.ToString();
panel.Controls.Add(gdv);

//set grid props

HTH.
