Setting default selection of a radcombobox in GridEditableItem

I have a RadGrid that is using a FormTemplate when inserting/updating values.

One of the values in my SQL Table is a bit flag. That is, it's going to be either true or false.

I can easily set this bit using a checkbox like the following in my FormTemplate:

<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Eval("CanBeFatal") != DBNull.Value ? Convert.ToBoolean(Eval("CanBeFatal")) : false %>' />

This essentially selects the checkbox if the flag is set to true. However, I would prefer to display a RadComboBox instead of a checkbox and set the selected item based on the value of the bit flag. I've tried various methods to achieve this, but haven't had any success. I'm not sure if this is even possible, but any help would be appreciated.

Based on the sample below, if my bit flag is set to false, I would like the RadComboBox to have the 2nd item selected. For simplity of this message, I am leaving out the various methods I used to evaluate the bit flag and attempt to set the selection in the sample to avoid confusion.

<telerik:RadComboBox ID="RadComboBox2" runat="server" >

<Items>

<telerik:RadComboBoxItem Text="Yes" Value="true" />

<telerik:RadComboBoxItem Text="No" Value="false" />

</Items>

</telerik:RadComboBox>

Thanks!

UPDATE:
I was finally able to set the selection after playing a bit more. Seems the value for the bit is case sensitive. I got it working by doing the following:

<telerik:RadComboBox ID="RadComboBox2" runat="server" SelectedValue='<%# Eval("CanBeFatal") %>'>

<Items>

<telerik:RadComboBoxItem Text="Yes" Value="True" />

<telerik:RadComboBoxItem Text="No" Value="False" />

</Items>

</telerik:RadComboBox>

Guess I spoke to soon. Hope this helps someone else!

I don´t speak very well english so my apologizes

I am user of telerik asp.net Ajax, and i like it .

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.

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?
