Still not the treelist that i was expecting :(

Hi everyone.
I don´t speak very well english so my apologizes

I am user of telerik asp.net Ajax, and i like it .
I have tried the aspxTreelist of Devexpress and i was expecting something alike, but is not, i am very upset.

I was expecting double click expand/colapse, sumary , Edit on place (like form) , scrollbars ,etc..

I have a project to finish and i use Telerik Asp.Net Ajax , but i have to buy only the component of aspxTreeList of Devexpress :(

I expect that issues comes in the next release.

Thanks

RadMenu and Caching

Hi,

I have a radmenu in a user control which is loaded dyanamically from another user control. On first load of the site, i.e. after compilation, the menu operates correctly but on subsequent loads it does not an iisreset is needed for the menu to work again. This is due to me having output caching enabled (sql cache dependency). I get the sys is not defined/telerik not defined errors.

Remove the caching and everything is fine. I need to cache the menu / data as it is intensive to get the data. Anyone know what I need to do so I can set the output cache and the menu continue to work properly?

Thanks,

Leon.

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?
