Hi all,

In design time, binding to and object datasource returns a "ID could not be set to property DataFieldID". However, if I run the application it works fine.

I'm testing http://www.telerik.com/help/aspnet-ajax/menu_dataobjectdatasources.html

Any idea?
I'm using Q2.2009

Hi,

I am facing an interesting problem with Grid having Child Table and with Slider paging.
When I expand and collapse child row, after collapse the pager of child table still gets displayed.
I have attached screen shots for the reference.

Thanks,
Avi

Dear Telerik
                       I placed a radcombobox inside a radgrid.I have autopostback set to true. I am using a GridTemplateColumn inside that I have filtertemplate inside that I placed a radcombobox .I also have itemtemplate inside that I have a checkbox.The combobox is populated with three values attended,unattended and all.when I select unattended/all in radcombobox it is showing the selectedvalue as attended only after postback.If attended is selected in radcombobox then the check boxes appears as checked.If unattended is selected from radcombobox then the checkboxes appears as unchecked.Please let me know what is wrong here.urgent please...

Here is the lines of code of importance

<telerik:GridTemplateColumn ShowFilterIcon="false" HeaderText="Attendance"  CurrentFilterFunction="EqualTo">
    <FilterTemplate>
    <telerik:RadComboBox ID="cmbAttend" runat="server"  DataTextField="ATTENDANCE_TYPE_DESC" DataValueField="ATTENDANCE_TYPE_ID"
    EnableViewState="true"  AutoPostBack="true">
    </telerik:RadComboBox>
    </FilterTemplate>
    <ItemTemplate>
    <asp:CheckBox ID="chkAttend" runat="server" />

Hi,

I found a blog with explanation and example of using RadcomboBox in MVC with LoadOnDemand.
I used the same version of Telerik.Web.UI and the same code but combo box on my page is totally disabled. RadComboBox in my case is placed in a partial view. I read somewhere that there is a problem with css styles if RadControls are placed in partial views but I couldn't find the solution to this.
However, when I placed it in a regular view page (non partial view) I got exception stating that control could not be modified inside server tags <%..%>. For that I found numerous solutions but none worked for me.
Do you have any suggestion of how to make ComboBox operational in partial view?
Do I maybe have to refer to all the JavaScript files needed for RadComboBox directly on the view page?

Thanks in advance.

Here's the sample of the partial view, if it means anything:

I am trying to get aggregate totals to appear for each group that I have specified in my grid.  I get a grid footer total for each column but I don't get a group footer total.  The group footer does not appear at all for the specified groups.  I think I have set all required ShowGroupFooter and ShowGroupPanel settings.  I will attach the code for how I have setup my grid.  I was wondering if anyone can point out what I am doing wrong.

I am using version 2008.3.1105.20 of the Telerik.dll.

Thanks in advance for the help.

After data binding with NeedDataSource, where is the appropriate place to toggle all items into edit mode and how?

Cheers,
Colin

I'm using the ComboBox to select from a list of Titles.  Some titles are quite long and look fine when word-wrapped in the dropdown section, but they don't fit in the single line input text tag.

Hi,

In my radgrid , I ve a grid client select column and also have paging turned on for radgrid with page size to 10.

Right now, if I select the header checkbox, only 10 records on first page gets selected. I sthere anyway , I can do so that if I check the header checkbox, I can have all the items across pages selcted.
For eg if I've 24 items , in first page I've 10 items, 2nd page I've 10 items and on 3rd page ,I've 4 items. Is ther any way ,if I select the header on firstpage, I can selct all 24 items.

Pls help me with code.

Thanks,
