Event behind 'Add new record' in RadGrid

Hi,

I have a quick question.

I'm trying to implement the RadGrid in BatchEdit mode.

I need to customise validation on some fields, and to do so I need to 'wire up' the event behind 'Add new record' button embedded on the grid.
E.g. the user added a new row/record and before adding another one I need to validate the added data.

I'm able to capture the events behind the 'Save changes' and 'Cancel changes' grid buttons but haven't been able to track down the 'Add new record'.

What are the client side and server side events behind this button?

Thank you in advance.

DropDown List Showing items already selected

Hi,

The RadAutoCompleteBox allows me to select items that were already selected.
That way it allows the user to duplicate items selected.

I't happens the same way on that sample http://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx

When i press 'n' and select Nancy. It goes to the box.
Then i press 'n' and select Nancy again. The i get 2 Nancyes on the box.

Is it expected?
Can i prevent it from showing selected items on the Drop Down?

Thanks in advance.

How to prevent NodeDrop event fire before RadAjaxManager1_AjaxRequest

I have a page with Radtreeview enable drag & drop. I implement a radconfirm to check exist node name when drop nodes

Script on client node dropping

function onNodeDropping(sender, args) {

var dest = args.get_destNode();

var source = args.get_sourceNode();

if (dest) {

var result = false;

for (var i = 0; i < dest.get_nodes().get_count() ; i++) {

var node = dest.get_nodes().getNode(i);

if (node.get_text() == source.get_text()) {

result = true;

break;

}

if (result) {

callConfirm(source.get_text());

return;

}

else {

dropOnHtmlElement(args);

}

And code to call confirm :

function callConfirm(nodeText) {

radconfirm(nodeText + ' folder is existing, Do you want to overwrite?', confirmCallBackFn);

return false;

}

function confirmCallBackFn(arg) {

var ajaxManager = $find("<%=RadAjaxManager1.ClientID%>");

if (arg) {

ajaxManager.ajaxRequest('ok');

}

else {

ajaxManager.ajaxRequest('cancel');

}

Code of RadAjaxManager1_AjaxRequest

if (e.Argument.ToString() == "ok")

{

lbStatus.Text = "OK";

}

else if(e.Argument.ToString() == "cancel")

{

lbStatus.Text = "Cancel";

}

But when drop an item on Radtreeview to another Node that the same node name, RadTreeView_NodeDrop event always fire before RadAjaxManager1_AjaxRequest. How to solve it?

RadFileExplorer views are not being disabled and Drag/Drop issues

I am trying to solve this problem, either:
a) Disable all drag and drop across all parts of the file explorer
or
b) Enable drag and drop inside the grid view, list view, tree view etc

1) As part of my testing and playing around with the file explorer, I tried setting these

            FileExplorer1.FileList.ListView.Enabled = false;
           FileExplorer1.FileList.Grid.Enabled = false;

           FileExplorer1.ListView.Enabled = false;
           FileExplorer1.Grid.Enabled = false;

           FileExplorer1.FileList.ListView.ClientSettings.AllowItemsDragDrop = false;
           FileExplorer1.FileList.Grid.ClientSettings.AllowRowsDragDrop = false;

All of which made no observable change to the control.
These however, did work as expected:

            FileExplorer1.TreeView.EnableDragAndDrop = false;
            FileExplorer1.TreeView.Enabled = false;

Why did the other lines have no effect?

2) To disable dragging and dropping for the file explorer, I'm told I can use this:

        explorer.get_fileList().get_grid().add_rowDragStarted(RowDragStarted);

        function RowDragStarted(grid, args) {
            args.set_cancel(true);
        }

Is there an easier way to disable or enable drag/dropping without going through every view for an entire File Explorer?

3) When inside the grid or thumbnail view, dragging a file over another folder does not trigger the move file event, but dragging over to the tree view does. How can I trigger this for the grid/thumbnail event?

Thanks,
Sean
