Problem with DefaultButton in Q1 2012

Hi to all,
I have upgraded my telerik controls from 2011.2.915.40 to 2012.1.215.40 with msi installer.
After uprade I discovered that defaultbutton declared for asp:Panel does not fire postback on pressing
the key Enter.
Here is small example. It works fine with older Telerik.Web.UI, but not with Q1 2012.

<%@ Page Language="C#" AutoEventWireup="True" CodeBehind="Default.aspx.cs" Inherits="Test._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title>Test</title>

</head>

<body>

<form id="MainForm" runat="server">

<telerik:RadScriptManager ID="RadSCM" runat="server" />

<asp:Panel ID="pnlWrapper" runat="server" DefaultButton="btnSearch">

<telerik:RadTextBox ID="tbSearch" runat="server" EmptyMessage="Search" Width="130" />

<telerik:RadButton ID="btnSearch" ButtonType="StandardButton" Text="Search" ToolTip="Searching" runat="server" OnClick="btnSearch_Click" />

</asp:Panel>

<asp:Label ID="lblMsg" runat="server" />

</form>

</body>

</html>

using System;

namespace Test

{

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

lblMsg.Text = string.Empty;

}

protected void btnSearch_Click(object sender, EventArgs e)

{

lblMsg.Text = "O.K. - Button fired";

}

Does anybody know where is the problem?
Thanks
-Marian

[Solved] RadGrid AddNewRecordButton problem on Prerender event

Hi,
I am using RadGrid from telerik version 2012.1.215.40.

I have two methods RadGrid_NeedDataSource and Page_Prerender event

I am trying to hide AddNewrecordButton based on user permissions

protected override void OnPreRender(EventArgs e)

{

try

{

//Hide controls on the page based on permission

//Code to hide control

// code to hide RadGrid AddNewRecordButton

RadGrid1.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = false;

}

base.OnPreRender(e);

}

catch (Exception ex)

{

HandleException(ex, ErrorControl);

}

This code doesn't hide the AddNewRecordButton from the grid.
But if i write the same code in RadGrid_NeedsdataSource event, it works. I also tried radGrid_PreRender event but that also not working.
If i add RadGrid.Rebind() method in prerender event, it works. But it fires the NeedsdataSource event again that i don't want.
All my code to hide/show controls based on the permissions is inside the PreRender event. So i don't want to use NeedsDataSource event just for hide/show of Add new record button.
Please suggest what is wrong with the PreRender event.

Hierarchical Grid Refresh

Hi,
I have a 3 level hierarchical grid.It is populated programatically (i.e. through 'DetailTableDataBind')

Each row in the middle-level grid has a hyperlink, which if pressed causes a dialog to be displayed (through RadWindowManager).

When the dialog is closed (by clicking 'Save'), the dialog closed, and calls a 'refreshGrid' function in the parent.

The 'refreshGrid' then does a 'ajaxRequest("RebindAndNavigate")'.

All pretty standard stuff, except it doesn't seem to refresh the contents of the 3rd level grid.

Am I missing something- does the rebind refresh all displayed 'programmatic-populated' children tables?

Cheers,
Steve

Refresh radgrid after File Save Dialogue box.

Hi Team,
I have a radgrid which I want to refresh when File Save Dialogue box is closed.

This is my code behind.

protected void btnPayment_Click(object sender, EventArgs e)

{

try

{

// do some stuff...

// This code below opens the Save File Dialogue box ..

String FilePath = Server.MapPath(".\\GiroPayments\\" + FileName + "");

System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;

response.ClearContent();

response.Clear();

response.ContentType = "text/plain";

response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");

response.TransmitFile(FilePath);

response.Flush();

response.End();

rgGiroPayments.Rebind();

}

catch() {}

}

If I comment this code to open save file dailogue box, grid gets refreshed. There is some prob with that code..
Could you help me out ?

Thanks,
Lok..
