[Solved] Attachment Column not functioning

[Mike]

I have an attachment column in my radgrid that has stopped functioning properly and I can't seem to figure out why.

                    <telerik:GridAttachmentColumn ButtonType="ImageButton" ImageUrl="~/Images/pdf_icon.gif" DataSourceID="odsLetter"  HeaderImageUrl="~/Images/pdf_icon.gif" HeaderTooltip="Download Letter"
DataTextField="FileName" AllowFiltering="false" AttachmentDataField="FileBLOB" AttachmentKeyFields="HTC_Key" FileNameTextField="FileName" UniqueName="Letter" SortExpression="LetterReleased">
                        <HeaderStyle HorizontalAlign="Center" />
                        <ItemStyle HorizontalAlign="Center" />
                    </telerik:GridAttachmentColumn>

I have the oncommand event set to run the gridCommand function to disable AJAX for the download.

<telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">
    <script type="text/javascript">
<!--
        function gridCommand(sender, args) {
            if (args.get_commandName() == "DownloadAttachment") {
                var manager = $find('<%= RadAjaxManager.GetCurrent(Page).ClientID %>');
                manager.set_enableAJAX(false);

                setTimeout(function () {
                    manager.set_enableAJAX(true);
                }, 0);
            }
        }

   -->
    </script>
</telerik:RadCodeBlock>

The grid loads and displays the right filename as a tooltip over the icon when I hover with my mouse which leads me to believe that the keyfields linkage is working right.  When I click the download icon, the page does a postback and reloads the grid without downloading the file from the BLOB field.

Any ideas about why this is happening this way?

Thanks

Mike

Hello Mike,

I'm not sure what causes the problem thus I created a simple demo that uses a similar approach. Please test it on your end and see how it differs from your code. This may help you find the issue.

Hi, I know it's been a while since last post but, could you provide the same sample with EntityDataSource?

Hi Jasmin,

I have attached a modified version of the previous example here. I hope this will be a good starting point for you.

Thank you very much for your answer. But, I've managed to make it work by myself :) Unfortunately, now I have problem that I've described in this thread http://www.telerik.com/community/forums/aspnet-ajax/grid/gridattachmentcolumn-with-editmode-inplace.aspx
Could you please help me with this one? :)
