Run Javascript after an Ajax Insert or Update

Hi,

I have my radgrid set to use Ajax. I would like to run some javascript after every edit or insert on my grid.

I have tried binding to the onGridCreated and onRowCreated events but they fire too often.

If there any way to say "after a row has been inserted or updated run this javascript" ?

Thanks
Sam

How to get node index ID

I am using the RadtreeView control in a ASP.Net webform. Depending on the data, I might display a tree with 1 branch or a Hierarchy tree with many branches and sub branches. Then the user will click on the node they want to select and the form will capture which node the user selected.

Everything works fine if the control shows only 1 branch with many nodes.

However, if the tree is showing a hierarchy with many branches and many nodes under each branch, and the user clicks on their choice of node, the return value is always a 0, 1 or 2. There are 3 main branches in the hierarchy so I assume the return value is the value of the main branch of the node that was selected.

How can I get the RadTreeView to always return the index number of the node I selected? Here is the click event that captures the user selection:

        protected void RadTreeView1_ContextMenuItemClick(object sender, Telerik.Web.UI.RadTreeViewContextMenuEventArgs e)
        {
                    HierarchyItem = e.Node.Index;
                    if (HierarchyItemSelected != null)
                        HierarchyItemSelected(this, EventArgs.Empty);
            }
        }

Client Resize Events don't fire

I have a RadScheduler that includes the following ...

OnClientAppointmenMoveStart="RadSchedulerAppointmentMoveStart"

OnClientAppointmentMoveEnd="RadSchedulerAppointmentMoveEnd"

OnClientAppointmentResizeStart ="RadSchedulerAppointmentResizeStart"

OnClientAppointmentResizeEnd="RadSchedulerAppointmentResizeEnd"

And in the JS handler for the ResizeStart event I have an alert.

When I run the page I note that the cursor doesn't change when I haver over the resize handle at the bottom of an appointment and that if I try grabbing it either, nothing happens (the JS alert doesn't fire) or the appointment moves. I guess this latter is 'cos I've grabbed slightly off the resize handle.

I can do nothing to resize the appointment.

FWIW, this is true in IE8 and IE6.

ProgressArea - Showing even when CustomValidator fails

I am having a RadUpload control with a Progress Area.

I have put client side validation to check valid file extension , file name entered etc.

I have a text box in the form (along with radupload and progress area), input of it has to be validated against the database. if the input is valid only it should upload the chosen document.
I have put a CustomValidator (server side) to do this validation.

What happens now even if the input is NOT valid, it uploads the documnt (progress area is shown) and then it shows the validation message.

Is there any way that I can supress this if invalid data is entered.

Thanks in advance.

Application Crashes on multiple clicks

I have a aspx user control page that has a LinkButton . The page uses some radajax controls too.
In Firefox(FF 3.6 and 4), if I rapidly keep clicking on the linkbutton .NET will come up with an "Invalid postback or callback argument" error. This error does not seem to happen when I click in IE. Normal single clicks on the linkbutton work fine, but it's when I click on the button repeatedly while the page is in the process of posting back that I run into trouble.
I was suggested to use "EnableEventValidation = false" but it ended up with some security hole. So, i was looking for some alternative solution other than "EnableEventValidation" property.

Raddock inside a formview bug/problem?

Hi,
I'm having a small problem with RadDock controls defined inside a formview, and I am not sure if it's my fault or if it's a bug.

In general, the controls inside a FormView's ItemTemplate and EditItemTemplate can have the same ID without any issues. In my case, I have a RadDock inside a formview with the controls defined inside the <ContentTemplate> of the RadDock. This leads to an error when I access the page that says: The type 'ASP.pages_mypage_aspx' already contains a definition for 'control'.

So:
Formview => ItemTemplate => RadDock => ContentTemplate => Control with ID X
Formview => EditItemTemplate => RadDock => ContentTemplate => Control with ID X

Is there a workaround for this that doesn't involve renaming the controls within the RadDocks?

Thanks.

Even when dropping event is canceled, the destination node is still expanded

Hi,

I'm working on a treeview with Client Side Api.

On ClientNodeDropping event I check (business rule) if the source node can be dropped over the destination node.

If the source node can be dropped, everything is OK, the ClientNodeDropped event is fired and the destination node is expanded.

If the source node cannot be dropped, I cancel the event, the ClientNodeDropped event is not fired BUT the destination node is still expanded: Why? How to cancel this behavior?

Regards,
Frederic Dobon

Drag and Drop not refreshing RadGrid on rebind()

I have a page with numerous grids for which drag and drop is enabled to reorder items within the grid. One grid, which I've adapted the code from other working grids, will not refresh the grid on screen even though the codebehind correctly changes the underling data

Below are my *.aspx file and *.vb file -- I've pulled the problematic grid out into it's own file and it persists in misbehaving on its own as well. I've about exhausted my creative ideas for solving the problem.

Any ideas?

Thanks,

Brad Smith
