Details:
I'm basically trying to implement the functionality of the example here (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultvb.aspx) on my own site, but instead of using a data source control located in the page markup (like in the example: SessionDataSource), I'm using a dataset that I get from some server code-behind. I am able to successfully get my double-clicked row into edit mode with my dropdowns successfully populated, however when clicking onto another row to update the one in edit mode, no-dice.
I've discovered that apparently the client-side JavaScript function updateItem() does not initiate an AJAX callback like I originally thought, so I've been trying to work my way around that. Currently I'm using my RadAjaxManager to perform an AJAX callback with the row index number like so:
function RowClick(sender,eventArgs)
{
if(editedRow && hasChanges)
{
hasChanges = false;
$find("<%= RAM.ClientID %>").ajaxRequest(editedRow);
}
}
This gets me to my server code. Awesome. But,
Problem: I must be accessing something wrong, because the GridDataItem cell text that I'm trying to obtain for the edited row all has the value " ".
Dim gdi As GridDataItem = FieldOpsScheduler.Items(rowIndex)
Dim d As DateTime = DateTime.Parse(gdi.Item("EndDate").Text) //<--FAIL
I've been scouring the Internet for hours now trying to find how I can pull off what I'm trying to do, but to no avail.
Additional Info: I'm using GridDropDownListColumnEditors on the front-side to do the editing for my table, declared like so:
<telerik:GridDropDownListColumnEditor ID="ddlce_SunAct" runat="server" DropDownStyle-Width="60px"></telerik:GridDropDownListColumnEditor>
So does anybody have any ideas on what I have to do to access the values that have been changed in my RadGrid?? Is the problem that I somehow need to rebind my RadGrid when clicking on a new row? If so how do I do that? Any solutions or ideas would be greatly appreciated. (Also although I'm doing this in VB.NET, feel free to write responses in C# if you wish as I understand that too. :-) ) Thank you in advance.
