Unknown Error with ScriptManager/RadGrid

I use one RadScriptManager as a user control with my menu. Everything has worked fine for weeks. Suddenly I am getting the following error all over the place.

This is occuring ever ytime I am updating a record across multiple RadGrids. If I put error trapping within the procedures I won't get this message. The data is being inserted and updated properly but the web app is failing afterwards. the weird part is that it runs fine on my machine but suddenly when published to another web it fails.

Is there some property that might have inadvertantly gotten changed? I haven't touched it, but it sure seems strange.

</div><br>

<br>

</div> <br>

</telerik:RadWindow>

& it's rendered html

<div id="RadWindowWrapper_ctl00_MainContent_EditSurvey_G3_dlgEditPage" class="RadWindow RadWindow_Default rwNormalWindow rwTransparentWindow popupDialog rwNoTitleBar" style="width: 506px; height: 260px; position: absolute; visibility: visible; left: 250px; top: 516px; z-index: 3002;" unselectable="on">

& this is main content

<td class="rwWindowContent" valign="top">

as you can see there is difference in width of those divs.

I have also attached the screenshot.

RadWindow using ContentTemplate and OOP

Hi Telerik,

Got another question for you guys. I've got my own RadWindow class, and it has a design-time control on my page:

<cs:GlobalSettingsRadWindow ID="DashboardGlobalSettingsWindow" Runat="Server" >

<ContentTemplate>

<div ID="GlobalSettingsDecorationZone">

<fieldset id="RefreshProperties">

<legend>Refresh Settings</legend>

<div id="RefreshArea">

<div id="RefreshLeftSide">

Auto-Refresh Enabled:

<asp:CheckBox ID="AutoRefreshCheckBox" Runat="Server" />

</div>

<div id="RefreshRightSide">

<telerik:RadNumericTextBox ID="AutoRefreshNumericTextBox" Runat="Server" Label="Auto-Refresh Interval (Minutes):" MaxValue="60" MinValue="1" ShowSpinButtons="True" Value="1" Width="225px" Enabled="False" LabelCssClass="riLabel LabelDisabled" DataType="System.Int32">

<NumberFormat DecimalDigits="0" AllowRounding="False" />

</telerik:RadNumericTextBox>

</div>

</fieldset>

<fieldset id="TabProperties">

<legend>Tab Settings</legend>

<div id="TabPropertiesArea">

<div id="TabLeftSide">

<telerik:RadListBox ID="TabsListBox" Runat="Server" AllowDelete="True" AllowReorder="True" EnableDragAndDrop="True" Height="95px" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" Width="150px" OnClientLoad="OnClientLoad" TabIndex="1" />

</div>

<div id="TabRightSide">

<telerik:RadTextBox ID="TabTextBox" Runat="Server" EmptyMessage="Enter tab name" Width="150px" />

<div id="TabButton">

<telerik:RadButton ID="TabTextApplyButton" Runat="server" Text="Add Tab" AutoPostBack="False" OnClientClicked="OnButtonClicked">

</telerik:RadButton>

</div>

</fieldset>

<fieldset id="CycleProperties">

<legend>Tab Cycle Settings</legend>

<div id="CycleArea">

<div id="CycleLeftSide">

Auto-Cycle Enabled:

<asp:CheckBox ID="AutoCycleCheckBox" runat="server" />

</div>

<div id="CycleRightSide">

<telerik:RadNumericTextBox ID="AutoCycleNumericTextBox" Runat="server" Label="Auto-Cycle Interval (Minutes):" MaxValue="60" MinValue="1" ShowSpinButtons="True" Value="1" Width="225px" Enabled="False" LabelCssClass="riLabel LabelDisabled" DataType="System.Int32">

<NumberFormat DecimalDigits="0" AllowRounding="False" />

</telerik:RadNumericTextBox>

</div>

</fieldset>

<div id="BottomButton">

<telerik:RadButton ID="ApplyGlobalSettingsButton" Runat="server" Text="Apply" AutoPostBack="False" OnClientClicked="CloseAndSave"/>

</div>

</ContentTemplate>

</cs:GlobalSettingsRadWindow>

Now, I work on it's children controls in Page_Init:

private void InitializeGlobalSettings()

{

//Global Settings Window Code.

GlobalSettings globalSettings = StateManager.GetStates<GlobalSettings>();

if (globalSettings.RefreshEnabled)

{

AutoRefreshCheckBox.Checked = true;

AutoRefreshNumericTextBox.Value = globalSettings.RefreshInterval;

AutoRefreshNumericTextBox.LabelCssClass = "LabelEnabled";

AutoRefreshNumericTextBox.Enabled = true;

}

TabsListBox.Items.Clear();

foreach (RadTab tab in LayoutManager.Instance.TabStrip.Tabs)

{

TabsListBox.Items.Add(new RadListBoxItem {Text = tab.Text, Value = tab.Value});

}

if (globalSettings.CycleEnabled)

{

AutoCycleCheckBox.Checked = true;

AutoCycleNumericTextBox.Value = globalSettings.CycleInterval;

AutoCycleNumericTextBox.LabelCssClass = "LabelEnabled";

AutoCycleNumericTextBox.Enabled = true;

}

This function is defined in MyPage.aspx.cs, not GlobalSettingsRadWindow.cs. This is necessary because I need to be able to have a handle on the CheckBoxes and various other controls.

I'd really like to fix this, though, as the controls are relevant to the RadWindow and not to the page.

Is there an easy way to do something like this without coupling the Page to the RadWindow class? Thinking along the lines of adding the controls to the RadWindow inside of its constructor, but how can I handle all of the various HTML markup which is not a System.Web.UI control?

Thanks

Sean

RadMultiPage causing PostBack & slowness of page rendering

We are using Telerik control in our page & we use RadMultiPage control along with RadPageView and RadTreeView

We use to transfer Item from Left multipage to Right as shown in the figure (query.jpg), via drag & drop or select an item from Left & click on button to add that item on right side.

Every time we do this it is causing post back of the page. Can you look into the code & help us in stopping

The postback of the page

NavigateUrl

I've been trying to change the NavigateUrl attribute of a Node in a TreeView from codebehind when the tree is initially loaded.

Protected Sub RadTreeView1_NodeClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeView1.Load

RadTreeView1.FindNodeByText("Upload Company Documents").NavigateUrl() = "~/upload/upload.aspx?b=" & Server.UrlEncode(Encrypt("&DT=C" & "&dummy="))

End Sub

This returns the following error: "Unable to cast object of type 'System.EventArgs' to type 'Telerik.Web.UI.RadTreeNodeEventArgs'."
In order to get around this problem I decided to do a Response.redirect and I can move to the desired page but I would like to be able to change the NavigateUrl attribute of a given Node during the Load of the TreeView.

Protected Sub RadTreeView1_NodeClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeView1.NodeClick

If RadTreeView1.FindNodeByText("Upload Company Documents").Selected Then

Response.Redirect("~/upload/upload.aspx?b=" & Server.UrlEncode(Encrypt("&DT=C" & "&dummy="))

End If

End Sub

Any help is appreciated.
