How do I use Ribbonbar Togglebuttons clientside?

Hi,
I want to be able to prevent the toggle button from posting back, while retaining the toggle state change in order to run some custom client-side code that represents the action taken by the button-click.

I noticed that one can cancel the postback by using:

args.set_cancel(true)

however when this is done, the toggle event itself is completely cancelled and the state remains as-is. There doesn't seem to be any Postback="false" options on the RibbonBar items, am I missing something?

Thanks,

RibbonBar

WindowManager UpdatePanel issue

Hi guys,

I’m having a issue with a RadWindow which contains an UpdatePanel in combination with the RadWindowManager.

When the popup is added during a GET request it throws an error:

Cannot unregister UpdatePanel with ID 'test' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.

When I disable the line: “createRadWindow()” it works and the popup is visible.

Why can’t the popup be created during a GET request?

I’ve read this page: http://www.telerik.com/support/kb/aspnet-ajax/window/cannot-unregister-updatepanel-with-id-updatepanelid-since-it-was-not-registered-with-the-scriptmanager.aspx

But I use the RadWindowManager because it recreates the RadWindow from the ViewState in a postback request.

In short I have two questions:
How can I fix this issue? I Need the RadWindowManager to recreate my windows so events for controls on these dialogs work properly.
Why does the popup work when created from a postback and not from a get request.

Kind regards,
DvdBrink

How do I find RadGrid on ItemCommand Event of RadGrid that lies inside RadTreeList

Hi Telerik,

I have RadGrid inside FormTemplate of RadTreeList. I have called an "ItemCommand" event on RadGrid that bascially deleted the uploaded files when user clicks the delete button within ItemTemplate of RadGrid. All its happening is good. But as soon as deletion gets done I'm trying to rebind the RadGrid , but its giving me EXCEPTION.

RadGrid element is null.

Can you help me ?

Below is my code:-

protected void FilesRadGrid_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

foreach (TreeListDataItem item in KnowledgeBaseRadTreeList.Items)

{

RadGrid FilesRadGrid = item.FindControl("FilesRadGrid") as RadGrid;

if (e.CommandName == "Del")

{

string[] values = e.CommandArgument.ToString().Split(':'); // ID:FilePath

if (System.IO.File.Exists(Server.MapPath(values[1])))

{

try

{

System.IO.File.Delete(Server.MapPath(values[1]));

}

catch { }

}

Glb_Entities.ExecuteSP(new object[] { "Usp_KnowledgeBase_Uploads_Delete"

, "@KnowledgeBase_Uploads_ID", values[0]

});

FilesRadGrid.DataBind();

}

While my RadGrid lies in Form Template of RadTreeList as :-

Telerik:telerik:GridTemplateColumn

We have a RadGrid with some telerik:GridTemplateColumns. We get a datasource and bind the grid. For first page grid behavour is consistent. But after page change, other columns in grid gets new values but itemtemplate columns persist the values from first page.

Grid Design Code :

<

telerik:RadGrid ID="rgvTest" runat="server" AllowFilteringByColumn="false"

AllowPaging="True" AllowSorting="True" MasterTableView-ShowHeadersWhenNoRecords="false"

AllowCustomPaging="false" AutoGenerateDeleteColumn="false" AllowMultiRowSelection="true"

AutoGenerateEditColumn="false" GridLines="None" ShowGroupPanel="True" OnItemDataBound="rgvTest_ItemDataBound"

OnPageIndexChanged="rgvTest_PageIndexChanged" OnSortCommand="rgvTest_SortCommand"

ClientSettings-ClientEvents-OnRowDblClick="GridRowDoubleclick" >

<

Columns>

<telerik:GridTemplateColumn HeaderImageUrl="../Images/priority_icon.png" UniqueName="Priority1"

HeaderTooltip="Priority">

<asp:Image ID="PriorityImage" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>
</Column>

Considering page size is set to 10.
After debugging , i got that OnItemdataBound event is called for first 10 records on load.
And after page change, it is called for 20 times but insted for 20 record of first page and second page, it is called twice for first 10 records... Strange but true.
If anyone has any idea abot this please help me out.
