Drag and Drop for RadTreeView

I need to have a drop zone for each node of a RadTreeView. I have added a RadAsyncUpload control in the NodeTemplate section. Are there any examples/demos for this scenario?

I followed the current demo structure. But in my case, the files are getting dropped for every upload control and not the specific one.

What is ClientState Input Hidden for?

Hi,

When I was browsing the DOM elements in the radWindow, I discovered a hidden textbox called ctl00_phMaster_radWindowTest_ClientState. My colleague received a report that at one point this hidden textbox (..._ClientState) had a value in it.

I would like to know:
- what is the role/function of the ClientState?
- under what conditions do the ClientState get populated?
- what values does the ClientState contain?

I use the radWindow in a secure site and don't want ClientState exposing any sensitive information.

Thank you,
Arie

Javascript crash when selecting all rows in grid

I have a RadGrid:

<telerik:RadGrid ID="radgridMachines" runat="server"

AllowSorting="True"

AllowMultiRowSelection="true"

AutoGenerateColumns="False"

OnNeedDataSource="radgridMachines_NeedDataSource"

OnItemDataBound="radgridMachines_ItemDataBound"

EnableViewState="false">

<ClientSettings EnablePostBackOnRowClick="false">

<Selecting AllowRowSelect="true" UseClientSelectColumnOnly="true" />

<Scrolling AllowScroll="true" UseStaticHeaders="true" />

<Resizing AllowColumnResize="true" ResizeGridOnColumnResize="true" AllowResizeToFit="true" />

<ClientEvents OnGridCreated="SelectAndResizeAllRows" OnRowSelected="TogglePrintControls" OnRowDeselected="TogglePrintControls" />

</ClientSettings>

<GroupingSettings CaseSensitive="false" />

<SortingSettings />

<MasterTableView DataKeyNames=

"CustomerID, CustomerName, PlantNumber, Route, MachineNumber, PlantName, MachineName, CustomerEquipmentID, TestPackage, PointID, Lubricant"

ClientDataKeyNames=""

AllowMultiColumnSorting="true">

<Columns>

<%--Fit to Contents--%>

<telerik:GridBoundColumn UniqueName="CustomerNumber" DataField="CustomerID" DataType="System.Int32" HeaderText="Cust #" HeaderStyle-Width="60px"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="PlantName" DataField="PlantName" HeaderText="Plant Name" ItemStyle-HorizontalAlign="Center"HeaderStyle-HorizontalAlign="Center"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="MachineName" DataField="MachineName" HeaderText="Machine Name" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="CustomerEquipmentID" DataField="CustomerEquipmentID" HeaderText="Machine ID" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="PointID" Visible="false"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

When I load 2600 rows, the browser gives me the following error:

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue. Script: http://localhost:50820/ScriptR…8-VKUfdnFfZq18eaxA2&t=7c776dc1:652"

The OnGridCreated event looks like this:

function SelectAndResizeAllRows(sender, eventArgs) {

var rows = $find('<%= radgridMachines.ClientID%>').get_masterTableView().get_dataItems();

for (var i = 0; i < rows.length; i++) {

rows[i].set_selected(true);

}

var grid = $find("<%= radgridMachines.ClientID %>");

var columns = grid.get_masterTableView().get_columns();

for (var i = 0; i < 4; i++) { //columns.length

columns[i].resizeToFit(false, true);

}

If I remove the first for loop, the grid loads properly. But I need to support selecting all rows. Is there another way to accomplish this? Why can't the grid handle this?

Thanks

RadGrid Paging on Multiple Lines but should be on a single line

I have a basic RadGrid control on a page. I only set the grid property AllowPaging="True" and the only Pager Style is <PagerStyle Mode="NextPrevAndNumeric" />. When the form loads up the paging is showing on 4 separate lines. I just want it to be on one line like all of the samples. Any ideas why this is happening? Do I need to apply CSS?

Filtering Dynamic RadGrid

I am trying to add Excel like filtering for a dynamic RadGrid. I found this example that shows filtering with client-side binding: http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/basic-filtering/defaultcs.aspx. However, I do not have GridBoundColumns because my RadGrid is dynamic. How do I go about adding Excel like filtering if I do not know the columns beforehand? Please show an example.

Thanks
