I have a databond radgrid and a databond detailtable within the radgrid. In the detailtable I have an extra checkbox column which is not databound.

Hi,
Currently I have 2 RadGrid (not using Ajax)
When I change the page index of RadGrid2, so that page postback and scroll to the top
How do I change the page index of RadGrid2, Scrollbar scroll to the header of RadGrid2
Sorry my bad English
Thanks

Hi,

I've followed the instructions on http://demos.telerik.com/aspnet-ajax/editor/examples/externaldialogspath/defaultcs.aspx and on http://www.telerik.com/community/forums/aspnet-ajax/editor/adding-functionality-to-a-customized-built-in-dialog.aspx in order to customise the hyperlink manager in the radeditor. This all works well except after the site has been compiled. After compilation and release the file LinkManager.ascx does not exist in the location specified in the property ExternalDialogsPath because it has been compiled into the bin folder. The compiled file name has also been changed so is not LinkManager.ascx, it is something like linkmanager.ascx.ab9a7aa3.compiled.

Is there a way around this that anyone knows?

Many thanks in advance,

Steve.

Hi, I’m upload and set image successfully to RadBinaryImage (image show correctly), but when try to access to DataValue property for save in database, the DataValue property is null. I need access to property, from click event of button named "btnSave", after image is uploaded.

Any Ideas.

Thanks for help!

Eloy.

ok,  I am getting the error

Missing operand before '=' operator.

when I try and export and the code is running fine in the grid.

Here is the code for the web part.  The error only occurs on the rebind.  It works fine in the grid itself.  Is there any way to narrow down the exact thing it is erroring on?

I am willing to pay for a support / solution to this problem, I just need it to work.

When I try to upload a file, I always get as filename "Object reference not set to an instance of an object." and I couldn't find the problem.

that's my web.config :

Hello,

I have a RadGrid inside of a RadAjaxPanel which is inside of a asp:Content control using master pages. Very basic page with the grid getting populated from an EntityDataSource. I have AllowPaging enabled on the grid. When the grid first loads (it has 2 pages), if I try to click on Next Page or Last Page, nothing happens. If I actually click the numeric "2" it will take me to the second page. If I go back to the first page and try the Next Page or Last Page buttons, they suddenly begin working. Its as if I must go to another page first before the paging buttons work.

Any thoughts?

Code:
<telerik:RadAjaxPanel ID="Ajax" runat="server">
        <telerik:RadGrid ID="PageGrid" runat="server" EnableViewState="false" DataSourceID="PagesDS"
            GridLines="None" AllowSorting="true" AutoGenerateColumns="false" AllowPaging="true"
            AllowFilteringByColumn="true" PagerStyle-AlwaysVisible="true">
            <ClientSettings EnableRowHoverStyle="true" EnablePostBackOnRowClick="true" />
            <MasterTableView DataSourceID="PagesDS" ClientDataKeyNames="ID" AllowNaturalSort="false">
                <Columns>
                    <telerik:GridBoundColumn DataField="Word" HeaderText="Word"
                        SortExpression="Word" UniqueName="Word" ItemStyle-Wrap="false">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn DataField="Definition" HeaderText="Definition"
                        SortExpression="Definition" UniqueName="Definition">
                    </telerik:GridBoundColumn>
                </Columns>
            </MasterTableView>
        </telerik:RadGrid>
    </telerik:RadAjaxPanel>
    <br /><br />
    <asp:EntityDataSource ID="PagesDS" runat="server"
        ConnectionString="name=BeST_Entities" DefaultContainerName="Database"
        EntitySetName="Terms"
        Select="it.[ID], it.[Word], it.[Definition]">
    </asp:EntityDataSource>

I have to Listboxes populated by a database. The goal is to copy items from RadListBoxSource to RadListBoxTarget. RadListBoxSource should insert the record via Autopostback into the database. The database is a Oracle 10.
The problem is, that the records in RadListBoxTarget won't be inserted into the database. Deleting from db works fine.
What's wrong with the code? Anyone got an idea?

Hi,

if I add a <telerik:RadWindow ID="a" runat="server" /> to an user control that is used in a complex page then I get the following error when the page is loaded in a web browser:

"Script control 'a' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl"

Unfortunately the page including this user control is too complex so I cannot easily provide a simple test case. I just thought I'd ask here if you had an idea what could cause this error and how to fix it.

Thanks
