I have RadWindow that opens up a popup modal dialog from a button and a button in a Radgrid on a given page. It behaves so incosistent.Sometimes one of those buttons bring up the modal. When i hit other button that brings up the same modal ,it does not show up. Then the modal popup stops functioning from any button click. I use Rad ASP Net Ajax Q2 2008. I am brand new to this. I am really bugged by this behaviour.
The code snippet on my page is
<!--Telerik Control for CreateNew.. Telerik Modal window -->
<telerik:radwindow ID="ModalPopup" runat="server" Behavior="None"
ClientCallBackFunction="RefreshList()" Height="600px" Modal="True"
Width="800px"
NavigateUrl="~/shared/PopupDialog.aspx?uc=~/Usercontrols/ProgramTypeMaint.ascx"
OpenerElementID="<%# btnAdd.ClientID %>" VisibleStatusbar="False"
VisibleTitlebar="False" KeepInScreenBounds="True" Overlay="True"
Skin="Vista"></telerik:radwindow>
This works sometimes and does not popup modal sometimes.
The grid is
<!-- List Display --->
<asp:Panel runat="server" ID="ResultPnl">
<asp:UpdatePanel runat="server" ID="ListPnl">
<ContentTemplate>
<telerik:RadGrid ID="grdProgramTypes" runat="server" AllowPaging="true"
AutoGenerateColumns="false" EnableEmbeddedSkins="false" GridLines="None"
Skin="Trizetto" ImagesPath="~/images/RadControls/Grid" Height="100%"
Width="100%" AllowSorting="true" Visible="false"
OnItemDataBound="grdProgramTypes_ItemDataBound" PageSize="10"
onneeddatasource="grdProgramTypes_NeedDataSource" >
<ClientSettings AllowColumnsReorder="true" ReorderColumnsOnClient="true">
<Selecting AllowRowSelect="false" />
</ClientSettings>
<MasterTableView>
<RowIndicatorColumn>
<HeaderStyle Width="20px" />
</RowIndicatorColumn>
<ExpandCollapseColumn>
<HeaderStyle Width="20px" />
</ExpandCollapseColumn>
<Columns>
<tzg:LocalizableGridBoundColumn ID="Name" HeaderText="Desc" HeaderButtonType="TextButton" DataField="Description"> </tzg:LocalizableGridBoundColumn>
<telerik:GridTemplateColumn HeaderText="Actions" HeaderButtonType="TextButton" UniqueName="Action">
<ItemTemplate>
<asp:ImageButton ID="btnModify" ImageUrl="~/images/editdoc16.gif" runat="server" ToolTip="Click here to edit this record" />
<asp:ImageButton ID="btnDelete" ImageUrl="~/images/delete.gif" runat="server" ToolTip="Click here to delete this record" />
</ItemTemplate>
<ItemStyle Width="40px" />
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
The btn modify also opens up the modal. It is also inconsistent in its behaviour. Looking for some insights asap
Thanks

Thanks for your response. I have to sanitise the code before i send it. So if you can answer the following, I will see if fixing this will fix the rest.
From the Telerik Radgrid, when a button is clicked, i call a javascript function to open up a RAdwindow modal, passing in a url. the script is
var oWnd=window.radopen(null,"ModalPopup") ;
oWnd.setUrl(url);
The radopen statement failed with the following error at runtime.
Microsoft JScript runtime error:Object doesnt support this property or method .
Thanks

To use radopen, radalert, radconfirm, radprompt and the other RadWindowManager's functions, you must have a RadWindowManager present on the page from where you call these functions. In your case, you have a RadWindow on the page as a standalone control, hence the problem.
Please either put the RadWindow in a RadWindowManager, or as an alternative - use the ASP.NET AJAX's find() method to get a reference to the RadWindow control and then call its show() method to open it.

Thanks for the response. I used either of those choices. It did not work for me. Then I had someone else try and it worked. I wanted to try the changes as you suggested once again and see. If I have issues I will let you know. Thanks

If the problem still persists however, I strongly recommend to send me a support ticket with a sample application that shows the issue that you experience. This way I could work directly on your code and provide you with he most appropriate solution for your case.

I implemented the Rad Window and it works fine in Firefox. In IE, sometimes the modal does not popup. Othertimes it works. If it repeats I will check back with you. Meanwhile I have anothe rproblem. I have a modal that pops up on a button click. I enter inputs and save and close the modal. When i click on the button again, i immediately see the old window hanging around with the data i enetered before and then refreshes with a flash with the new window. I tried to use DestroyOn close. That makes the modal look small and weird the second time on. How do I fix it?
Thanks
Geetha
Yo don't need to use DestroyOnClose in such scenario. Just set ShowContentDuringLoad to false and ReloadOnShow to true.
If you still experience problems, please open a support ticket and send me your project.
