loaded usercontrol has a gridview whose selection is not showing in postback

Question

Hello Loaded usercontrol has a gridview whose selection is not showing in postback I have a page main.aspx.cs that loads at runtime web controls (.ascx) One of the controls has a gridview and when I select an item in the gridview I want to use this value in the main page (the main.aspx.cs) I have everything turned on (enable viewstate =true for the gridview) I tried on selected index changed and selected index changing event handlers to assign the gridview1.selectedvalue to the viewstate but wasn't able to get anything in the postback instance of the page. I was able to add the value to the session but not the viewstate. I can also add it to the page.form.attributes and recall it in the postback The problem in the page.form.attributes  is that the value called in the postback is not the last selected index but it is delayed by 2 selected indexes so it gives -1 1 2 instead of 1 2 at consecutive postbacks when selecting first and second rows (this is new) I tried to response.write in the loaded control the value of gridview1.selected index on the control's page load event and it gives a delay of 1 browser trip ramzi1978 at hotmail thanks

I found a solution on microsoft's website http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.selectedrowstyle(VS.80).aspx you need to use the gridview row void CustomersGridView_SelectedIndexChanged(Object sender EventArgs e) { // Get the currently selected row using the SelectedRow property. GridViewRow row = CustomersGridView.SelectedRow; // Display the company name from the selected row. // In this example the third column (index 2) contains // the company name. Response.Write( You selected  + row.Cells[2].Text + .); void CustomersGridView_SelectedIndexChanging(Object sender GridViewSelectEventArgs e) { // Get the currently selected row. Because the SelectedIndexChanging event // occurs before the select operation in the GridView control the // SelectedRow property cannot be used. Instead use the Rows collection // and the NewSelectedIndex property of the e argument passed to this // event handler. GridViewRow row = CustomersGridView.Rows[e.NewSelectedIndex]; // You can cancel the select operation by using the Cancel // property. For this example if the user selects a customer with // the ID ANATR the select operation is canceled and an error message // is displayed. if (row.Cells[1].Text == ANATR) { e.Cancel = true; Response.Write( You cannot select  + row.Cells[2].Text + .); }}

here is a way to duplicate the issue: add a gridview that reads from a test database with select enabled viewstate=true; add on load response.write(gridview1.selectedindex.ToString()); press F5 and click on an item you have to click again to see the correct selected index any ideas? if i add a dropdown when i select and then i select in the gridview the response.write dropdownlist1.selectedindex is correct thanks
