Unable to get value of the property '_getHierarchicalIndex': object is null or undefined

getting the following error
Unable to get value of the property '_getHierarchicalIndex': object is null or undefined
when i try to remove a node on the client side

Following is the sequence
- I am creating some initial nodes from the server
- I am clearing the treeview on some client operation
- After clearing, I am again populating the treeview on the client side itself.
- After that When I expand some node and try to delete any node under it, I get the above error.

This error is also intermittent, it comes for some nodes and not for some.
I tried to debug the js code, but without success. Can you please point me to some points, which can get me to the crux of the problem. I am not able to identify what might be causing this script error.
I get this error in the latest(Q12012) and its previous version of telerik asp.net ajax control toolkit.

InvalidOperationException when mixing AllowFilteringByColumn="true" and ControlParameters

Hi,

I have two RadGrids bound to two different EntityDataSources. The 2nd datasource uses WhereParameters and ControlParameters to pass the SelectedValue of the first grid to the datasource of the 2nd grid. This all works fine, until I enable filtering on the 2nd radgrid. As soon as I set

AllowFilteringByColumn="true"

on the MasterTableView of the 2nd grid, I get the following exception:

WhereParameters cannot be specified unless AutoGenerateWhere==true or Where is specified.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Databinding with ajax causes paging to fail

Hi All

Scenario:
Page with a Telerik radGrid. A WCF service provides data (JSONP) dat is bound to the Radgrid. Page size is set to 10.

Problem:
The data is correctly loaded into the gridview. When loading 1 record from the wcf service, the paging bar still says: 11 items loaded.
As I understand from debugging, a fixed number equal to the page size of "items" is created in the tabel. Those items are then filled with the data records, an the remaining records are made invisible. That works correct, but the paging still counts those hidden rows...
When I add more than 10 rows, the 12 rows are shown on the first page,while max page size is 10.

Even when I hardcoded bind to an JSON string, the data is shown correct in the grid, but paging is displayed incorrectly.

the code for loading data:

function getData() {

var proxy = new window.LiveIdService.ILiveIdService();

proxy.set_enableJsonp(true);

proxy.GetUserList(null, updateGrid);

}

function updateGrid(result) {

var tableView = window.$find("<%= RadGrid2.ClientID %>").get_masterTableView();

tableView.set_dataSource(data.UserList);

tableView.dataBind();

}

My radGrid

<telerik:RadGrid ID="RadGrid2" runat="server" GridLines="None"

</CommandItemTemplate>

I hope this is sufficient info to help me fix this paging problem, if not please let me know.

[Solved] Removing all the items on itemsrequest event in javasript

Team

I am using rad combobox in my application for searching.

Whenever user type something in combobox it shows me related data.

I have used OnItemsRequested event for this.

I am having requirement that result drop down won’t show up until I type 3 charactors in combobox

I am using OnClientItemsRequesting event as follow to suppressed OnItemsRequested event.

function onItemsRequesting(sender, eventArgs) {

if (eventArgs.get_text().length < 3) {

sender.hideDropDown();

eventArgs.set_cancel(true);

}

else {

sender._loadingMessage = "Searching for " + eventArgs.get_text() + "...";

}

I am using telerik V2011.3.1115.40

Initially combo doesn’t contain any items. It is working fine first time but whenever I remove the characters & number of characters become to 2 & press another letter even then it shows me previous result for few seconds & then shows proper result. Is there any reason for this?

Can you please let me know how to remove all the items of the radcombobox in OnClientItemsRequesting event?

It might resolve the problem.

If you have any other resolution for this please let me know.
