Hi,
i've got a problem with telerik combobox in IE, when I enter the combobox and press BackSpace it redirects me to the previous page.

In FF, it works fine. Don't you know where could be a problem?

Here is my code:
<telerik:RadComboBox ID="comboCompany" runat="server" Width="304px" OnClientSelectedIndexChanging="LoadSites">
</telerik:RadComboBox>

Thanks for answer.

RadGrid Item Missing Border when null

Hello,

I have a RadGrid populated from a method in a class file. When I bind the grid one of the columns is populated with a space, " ". For some reason, this causes the RadGrid to not place borders/gridlines around the items in that column. I've attached an example of what this looks like.

Any help would be appreciated.

Thanks,
Casey

Overwrite header background color of custom skin

Hi all,

I'm having a custom skin which is modified from Telerik Skin.

EnableEmbeddedSkins="false" Skin="MySkin"

In my website, user has his/her own favorite color. And I would like to apply that color for Grid header.
For example, user A has Orange color and the background color of RadGrid header must be orange.

Are there any ways to modify the "MySkin"?

Regards,

Andy.

EnableEmbeddedSkins="false" Skin="MySkin"

Basic Window question

I'm coming from a ASP .NET AJAX / Toolkit background and I'm used to developing windows that follow this pattern:

In the ASPX I would have an UpdatePanel in the body of the page and a ModalPopupExtender which would contain an UpdatePanel. The event handler for the trigger on the page would populate values in the ModalPopupExtender's UpdatePanel and then display it via the Show() method. The event handler for the Save button on the ModalPopupExtender would do any additional validation/persistence and, if successful, update values on the calling page's UpdatePanel and Hide() the dialog window.

Is it possible to implement this pattern using the Prometheus Window and AjaxPanel/AjaxManager without having to write Javascript?

RadGrid and a CSV File

I have a CsvReader class that populates a DataTable from a csv formatted file. The file has no headers, the basic layout of the csv file is
1231,13213,1421,12414 (Obviously fake data)

I'm having trouble trying to figure out how I take this information and create a hierarchy in my RadGrid. The first value in the row is my parent and the other values are the children.

I've been trying to follow along the tutorials and demo's but for some reason it is not clicking.

EditTemplate and Insert New Record issue

Hi,

I have a issue at the moment which I can't seem to fix.
Basically I have my own custom edit form which looks like this:

<EditFormSettings EditFormType="Template">

<FormTemplate>

<div style="padding: 5px;">

<telerik:RadDatePicker ID="RadDatePicker1" SelectedDate='<%# Bind( "HolidayDate" ) %>' runat="server" /><br />

<asp:LinkButton ID="Button1" Text='<%# Iif (TypeOf Container is GridEditFormInsertItem, "Insert", "Update") %>'

runat="server" CommandName='<%# Iif (TypeOf Container is GridEditFormInsertItem, "PerformInsert", "Update") %>' />

<asp:LinkButton ID="Button2" Text="Cancel" runat="server" CausesValidation="False" CommandName="Cancel" />

</div>

</FormTemplate>

</EditFormSettings>

This works fine when editing a record, but if I click 'Add new record' I get this error message:

System.InvalidCastException: Specified cast is not valid.

It points to the RadDatePicker and I found that if I remove the SelectedDate it works fine. But I need the selected Date when editing an existing record.
Could someone tell me (which I assume is simple!) how to resolve this?

Control registration with AJAX MANAGER

I am getting the following error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Script control 'grWFSteps' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

My page layout is as follows

Master page that has AJAXMANAGER

Page derived from the Master page has a user control say UC1

        User control UC1 has a radgrid RADGRID1
        User control UC1 has a AJAXMANAGERPROXY where trigger and updated control are RADGrid1
        RadGrid1 can be updated using another user control UC2

                     Now in UC2, there is another user control UC3

                                    UC3 has an AJAXManagerProxy where some controls in UC3 update other controls in UC3

When the trigger in UC3 is initiated I get the error above.

My question is that the controls are already registered with the AJAXManagerProxy in UC3 as shown below. Where else do they need to be registered?

<

telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanelWF" runat="server" />

<

telerik:RadAjaxManagerProxy ID="AjaxManagerProxyWF" runat="server">
