[Solved] RadGrid HeaderContextMenu PostBack not firing ItemClick

Hi,
I am adding a new menu to my RadGrid HeaderContextMenu :
var newFilterItem = new Telerik.Web.UI.RadMenuItem();
newFilterItem.set_text("Clear All Filters");
newFilterItem.set_postBack(true);
sender.get_items().insert(0, newFilterItem);

I expect that since postback is true, when menu is clicked, ItemClick event of HeaderContext menu should be fired.
Postback is happening but ItemClick event is not firing!! Is there any other event that gets fired when postback is true for Header Menu?

Accessing controls in CommandItemTemplate of child grid

In the following code snippet I have a child grid that has a hyperlink in the CommandItemTemplate, how can I access this so that I can set the url for the hyperlink (It needs the id field from the parent row in it)? I've tried several places such as PreRender and OnItemDataBound but I haven't been able to find anywhere where FindControl doesn't return null.

This was my last try in the Prerender event of the parent Grid.

protected void radPurchaseOrder_PreRender(object sender, EventArgs e)

{

foreach (GridDataItem item in radPurchaseOrder.Items)

{

if (item.Expanded)

{

HyperLink link = item.FindControl("linkDoInvoiceExport") as HyperLink;

if (link != null)

{

//do stuff here if the above ever isn't null

}

<telerik:RadGrid ID="radPurchaseOrder" runat="server" AllowPaging="True" ClientSettings-ClientEvents-OnGridCreated="GridCreated"

[Solved] Hide Columns - Several Detail Tables at a single hierarchy level

Greetings,

I have a radgrid where its datasource is bound from an XML output. It has multiple hierarchy levels and has (auto genearted columns = true). On the 2nd level of the hierarchy there are several details tables that automatically get binded. (Please reference image below). However, there are columns which get auto generated displaying the ID's for the detail tables. My goal is to programmatically hide all the ID's in all detail tables. I can hide the CusomterID programmatically using the following code below:

For Each item As GridDataItem In Radgrid_CRGList.Items

''Root Level of Radgrid
Radgrid_CRGList.MasterTableView.GetColumnSafe("OrderID").Visible = False

''2nd Level of Radgrid - 1st Detail Table
Radgrid_CRGList.MasterTableView.DetailTables(0).GetColumnSafe("CustomerID").Visible = False

''2nd Level of RadGrid - 2nd Detail Table
''' Place code here to hide EmployeeID ''

Next

The issue is that I can't figure out the code to hide the EmployeeID in the 2nd details table on the same hierarchy level of the radgrid. Please Help!

[Solved] Entries Collection Error when used with RadAjaxManagerProxy

In my case there seems to be a problem with the RadDropDownTree in which the DropDownTreeEntries collection is not properly managed by RadDropDownTree. When RadAjaxManagerProxy is configured as shown in the following code example the Entries collection is always appended to, It never shrinks. If I comment out the line containing AjaxUpdatedControl then the RadDropDownTree begins working correctly again. I also tested this in a straight up ASP page with RadAjaxManager and found that RadDropDownTree works as expected. It seems that this problem only exists if using a RadAjaxManagerProxy on a Content page. Has anyone else seen this behavior and is there a workaround.

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadButton2">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadGrid1" UpdatePanelCssClass="MasterUpdatePanel" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManagerProxy>

Issues with Menu

I'm following this:

http://demos.telerik.com/aspnet-ajax/menu/examples/programming/declarativedatasources/defaultvb.aspx

and first of all, the "flow" is vertical by default and I can't get it to change to horizontal no matter what I do. Also, the xml file in the example will not work with an xml data source when you choose "text" as the DataTextField - it says "Object of type System.Web.UI.Controls.XmlHierarchyData does not have a text property. It only works when I put a text property on the <Menu> tag like this: <Menu Text="Menu">

What gives? Why can't I get this to work in any kind of way?

Hide modal while performing a partial postback inside a ajaxpanel?

I have a modal that gets dynamically loaded when a user clicks a button on a grid. The modal content is populated from an ascx user control. It has to be inside the update panel as the values change dynamically when the user clicks the grid.

I add the following to display the modal:

Me.LoadMyUserControl("~/controls/Log.ascx", Panel1)

Dim MessageScript As String = "$('#modal-interact').modal('toggle');"

ScriptManager.RegisterStartupScript(Me, GetType(Page), "UniqueID1", MessageScript, True)

The problem is, when i submit the modal since the modal is ajax-y it does a partial postback causing the modal not to close.

I've tried using an onclientclick to close the modal then postback via javascript but the postback does not occur.

This will close the modal, but not fire the postback:

<script type="text/javascript">

function confirmthis()

{

$('#modal-interact').modal('hide');

return true;

}

</script>

Then of course removing the onclientclick and just handling the onclick triggers the postback, but does not hide the modal.
