Questions on UI for ASP.NET AJAX Forum

Not sure what I'm doing wrong. I have an operation (initiated from a GridButtonItem click) that occurs inside an async postback. Depending on the results of the operation I need to update image and label controls hosted in a RadWindow, display the RadWindow, wait for the user to click a button, determine the button that was clicked and continue with the operation.

For the life of me I can't get the RadWindow to open with generating an exception. I've stripped out the RadGrid and simplified the code to try to find the problem but alas, no joy.

My aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ZZRadWindow.aspx.cs" Inherits="SitefinityWebApp.ZZRadWindow" %>

<!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></title>

</head>

<body>

<script>

function OpenWindow()

{

var wndMgr = GetRadWindowManager();

wndMgr.open("", "ConfirmPlaybackWindow");

return false;

}

</script>

<form id="form1" runat="server">

<div>

<asp:ScriptManager runat="server" ID="ScriptMgr" />

<asp:UpdatePanel ID="WindowUpdatePnl" runat="server">

<ContentTemplate>

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

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" ReloadOnShow="true" runat="server" Skin="Forest" EnableShadow="true" Font-Bold="False" Modal="True">

<Windows>

<telerik:RadWindow ID="ConfirmPlaybackWindow" runat="server" DestroyOnClose="False" Skin="Forest" Modal="True">

<ContentTemplate>

<div class="confirmationDlgWrp">

<div class="alertWrp">

<asp:Image ID="AlertImg" runat="server" CssClass="dlgIcon" />

<asp:Label ID="AlertLbl" runat="server" CssClass="dlgLabel" Text="Hello World" />

</div>

<div class="confirmationDlgBtnWrp">

<asp:Button ID="YesBtn" runat="server" CssClass="dlgYesBtn" Text="Yes" />

<asp:Button ID="NoBtn" runat="server" CssClass="dlgNoBtn" Text="No" />

</div>

</ContentTemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

<asp:Button ID="PostBackButton" runat="server" Text="Do Postback" />

</ContentTemplate>

</asp:UpdatePanel>

<p />

<asp:Button ID="Button1" runat="server" OnClientClick="return OpenWindow()" Text="Open RadWindow" />

</div>

</form>

</body>

</html>

And my codebehind looks like this:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace SitefinityWebApp

{

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

{

private static int PostBackCount = 0;

protected void Page_Load(object sender, EventArgs e)

{

if (IsPostBack)

{

msgLbl.Text = string.Format("{0}<p/>PostBackCount: {1}", msgLbl.Text, ++PostBackCount);

string script2 = "<script type=\"text/javascript\">OpenWindow();</script>";

ScriptManager.RegisterStartupScript(WindowUpdatePnl, typeof(string), "OpenWindow", script2, false);

}

Clicking the button located outside the UpdatePanel result in the RadWindow displaying without error. Clicking the postback button located inside the UpdatePanel results in the following exception:

Microsoft JScript runtime error: Sys.InvalidOperationException: Can't be called after dispose

Any idea what I'm doing wrong here?

Thanks -- Steve

Getting frustrated - 2 errors that keep popping up!

Alright...every time I drag an "old" telerik control that uses version 2009.3.1314.20 of the .dll, it overwrites the newer version of 2009.3.1314.35. As a result, it gives me the following error:

"Could not load file or assembly "Telerik.Web.UI, Version=2009.3.1314.35...or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

I have tried for two days to figure out how to fix this, or to stop this incessant overwriting, but I have been unable to do so. Worse still, I am now at least 2 days behind on my project, and my supervisors are wondering if we shouldn't just go back to the 'old' tools we had instead of using Telerik, because this looks like (at least, it does to them) that Telerik has some serious stability issues to address. I can't say I disagree....

The second problem is an error that says:

"Cannot create an object of type 'System.String[]' from its string representation 'KeyField' for the 'DataKeyNames' property."

This error is especially infuriating because I have the EXACT SAME CODE on another page....and it WORKS! I have no idea what the problem is, or how to fix this. Attached is a screenshot (cropped) of the errors in question. I really need some help here before I throw my monitor out the nearest window!

The length of the string exceeds the value set on maxJsonLength property

There is a known problem with maxJsonLength property:

http://support.microsoft.com/kb/981884

However, this hotfix did not work. Maybe because it is for the MS UpdatePanel?

If so, how can this be resolved? This error comes up when grid tries to pull too many rows.

Dynamically change FormTemplate in EditFormSettings

                                <span class="des"><asp:Label ID="lblDestination" runat="server" Text='<%# Eval("Destination") %>' /></span>
                            </td>
                        </tr>

Resize RadWindow based on Page Content

Dear all,

I’m trying to open the Rad window as modal and to be able to calculate the size of the opened window based on the opened page size i.e 400x400 and keep it centered. I don’t not want to use the autosize property.

Below is my Rad window setting as well the JS code which I use to recalculate the window size to fill the window.

Yourhelp is appreciated to open the modal window centered and in correct size based on the content page.



var oWnd = window.radopen(_EncryptedURL, "AdvancedForm");
oWnd.set_title(pageTitle);
resizeRadWindow(oWnd);
 
function resizeRadWindow(radWindow) {
 
    var windowHeight = $(window).height();
    var windowWidth = $(window).width();
 
    windowHeight = (windowHeight * 97.5) / 100;
    windowWidth = (windowWidth * 98) / 100;
 
    radWindow.moveTo(10, 10);
    radWindow.setSize(windowWidth, windowHeight);
}

<

rad:RadWindowManager ID="RadWindowManager1" runat="server">

<Windows>

<rad:RadWindow ID="AdvancedForm" runat="server" Modal="True" OpenerElementID="showDialog"

InitialBehaviors="None" ShowContentDuringLoad="false" Behaviors="Close" OnClientClose="refreshScheduler"

ReloadOnShow="True" Title="" NavigateUrl="" VisibleStatusbar="False">

</rad:RadWindow>

</Windows>

</rad:RadWindowManager

Hide delete button on children

Hi,

I want to give the users the option of deleting items on a treelist grid, but I only want them to delete a full node. Or, to put it on a single question, is it possible to show a delete button only when Parent ID is null?
