Sometimes there are duplicate sub menu items created for no apparent reason. Sometimes it works fine.

Say there are 3 submenu items under a parent, select one of those, move off it, go back to it a second later and those same 3 subitems have been repeated usually 1-3 times so that there are now 6-12 items under the parent. It's also always the full set of subitems that are repeated, it's never just 1 or 2 out of the 3.

It seems to be somewhat random. The menu is created in code and I've confirmed that code is ONLY being hit on the initial page load and not any postbacks. The only other interaction in code with the menu is to enable or disable certain items depending on what the user had selected.

Other than the client menu item click handler, all code referencing the menu is on the server side.

RadToolTip not showing when using a custom asp.net .ashx image handler

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

<telerik:RadToolTip ID="RadToolTip2" runat="server" TargetControlID="imgMain" Width="400px" RelativeTo="Element" EnableShadow="true" Position="BottomCenter" Animation="Slide" AnimationDuration="300" ShowDelay="200" Skin="Vista" HideEvent="LeaveToolTip">

</telerik:RadToolTip>

Hi im using the RadToolTip as above.
Im also adding a Image inside the RadToolTip at runtime, the ImageUrl of this Image is set via my own custom Image Handler which is used within the site and works fine.

When the user hovers over 'imgMain' the RadToolTip should show the same image but at a different size, but all im getting is the RadToolTip showing the title.
If i hard code the Image Urls into the Image inside the RadToolTip is shows fine so i know its not a problem with my ImageHandler.

Is there any known issues with dynamically showing images from a Image Handler iside a RadToolTip?

My Server side code is below

imgMain.ImageUrl = String.Format("~/dbimagehandler.ashx?record=product&empty=showt&imageno=1&recno=-1&wid={0}&hgt={1}&productid={2}", "188", "196", this.ProductId)

imgMain.AlternateText = ds.Ds.Tables["Table"].Rows[0]["Title"].ToString();

imgMain.ToolTip = ds.Ds.Tables["Table"].Rows[0]["Title"].ToString();

RadToolTip2.TargetControlID = imgMain.ID;

Image imgsmall = new Image();

imgsmall.ImageUrl = String.Format("~/dbimagehandler.ashx?record=product&empty=showt&imageno=1amprecno=-1&wid={0}&hgt={1}&productid={2}", "376","392", this.ProductId);

RadToolTip2.Controls.Add(imgsmall);

Any help on this would be mcuh apreciated.

radgrid ajax refresh not working

Hi,

I'm using a rad grid to show line items for an invoice. Each row has an image button column used to delete the row when clicked.
I prefer to do this on the client and everything works fine until I call rebind to update the grid. It just doesn't work.The results in my data store show's the row has been delete. I am using a content page if that makes a difference. Here is my code. Thanks for your help.

function DeleteRow() {

EstimateWebService.DeleteEstimateItems(rowId.Id, OnDeleteRowSucess)

}

function OnDeleteRowSucess() {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

}

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"

EnableViewState="false" onajaxrequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnAddNewRow">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="grdEstimateItems" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<telerik:AjaxUpdatedControl ControlID="grdEstimateItems" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

{

if (e.Argument == "Rebind")

{

//RadGrid1.MasterTableView.SortExpressions.Clear();

Checkbox will not show in GridTemplateColumn

I have a dataset coming back that has 2 columns with Y or N values that indicate whether someone received a packet and whether or not they attended an event.

I need to have a checkbox in the datagrid that is checked if the value is "Y" and not checked if the value is "N"
The problem I'm having is I can't even get the checkboxes to show up in the datagrid, and since they aren't there, when I try to set the checkbox in the code behind, the chkBox object is nothing, so it throws an error.

Here's my datagrid:

<telerik:RadGrid ID="RadGrid1" OnSortCommand="RadGrid1_SortCommand" EnableViewState="true" MasterTableView-RetrieveAllDataFields="false" MasterTableView-CanRetrieveAllData="false" EnableEmbeddedSkins="false" runat="server" AllowPaging="true" AllowSorting="true" Width="930px" Height="150px" PageSize="25">

<telerik:GridBoundColumn DataField="PACKETRECEIVEDIND" Display="false" DataType="System.String">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

The last 2 columns are hidden and contain the Y/N value. I can get that value in the ItemDataBound Sub, but I can't find the checkbox, so the chkBox.Checked = True/False step errors. If I skip setting the checkbox value, the grid loads, and I see the two checkbox columns, but the columns are empty.

lstr_PacketReceived = item("PACKETRECEIVEDIND").Text

Dim

chkBox As CheckBox = DirectCast(e.Item.FindControl("CheckBox1"), CheckBox)

If Not (lstr_PacketReceived Is Nothing) Then

If lstr_PacketReceived.Equals("Y") Then

chkBox.Checked = True

Else

chkBox.Checked = False

End If

Any idea what I'm doing wrong here? I'm sure it's something simple, I just can't seem to figure this on out.
Thanks
