Hiding 'AddNewRecordButton' and Header after postback

In my radgrid, on click of AddNewRecord, I open a user control with a search textbox and button. To hide the AddNewRecordButton and Header I have on RadGrid1_ItemCommand I have the following:

if (e.CommandName == RadGrid.InitInsertCommandName)

{

         this._RadGrid1.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = false;

this._RadGrid1.MasterTableView.ShowHeader = false;

But when the search textbox retrieves results and I select one of the entries, a postback is done to display the selected the value, after which the header and AddNewRecordButton are again visible though, the user control is still open. Is there a way to hide it after the postback?

Row select causes other rows to deselect

I have a grid with a GridClientSelect column. Clicking anywhere in the row other than the checkbox for that row causes all other selected/checked rows to deselect. How do I stop this. I want the row to only be selected by clicking the checkbox. I have shown in attached screenshots.

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?
