I need some help ith one o the demos I am trying to use.
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx

I have created a very similar version except that I am using a pop up window instead and 2 ascx user control forms which just allows the user to enter all info and then edit some info.

The first problem is: with this code behind in the RadGrid1_PreRender event.

if (!this.IsPostBack)

{

this.RadGrid1.MasterTableView.Items[1].Edit = true;

this.RadGrid1.MasterTableView.Rebind();

}

I get this error when my page loads.
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Now I am using a hierarchy grid which is pullong data from the same db.

The second issue I am having is the Insert and Update button in the user control form .ascx file. I have this code for the update button which is directly from the demo.

<asp:Button ID="btnUpdate" Text="Update" runat="server" CommandName="Update" Visible='<%# !(DataItem is Telerik.Web.UI.GridInsertionObject) %>' Font-Size="0.9em" />

</td>

<td>

<asp:Button ID="btnCancel" runat="server" Text="Cancel" CausesValidation="false" CommandName="Cancel"

Font-Size="0.9em" />

For some reason the DataItem is not liked and I am getting this web page request error when I go to edit a record.
Error: Sys.WebForms.PageRequestManagerServerErrorException: c:\test\Web Projects\Sites\Industries VS2008\ Industries\Board\Controls\Admin\EmailSettingsUpdate.ascx(172): error CS0103: The name 'DataItem' does not exist in the current context

Can anyone shed some light here?

Thanks

Hide inner panel items based on combobox selection in first panelitem

I'm wondering if it's possible to show/hide (set visible to true or false) nested panel items in the panelbar based on a combobox, etc selection in the first panelitem?

Example, a panelbar with 10 total panelitems contained in it. First panelitem has a combobox. User selected a value from combobox and only certain subsequent panelitems show, the rest get hidden.

Is this possible? Is it at all possible to do this in jquery by getting the id of the parent object and then walking down to the appropriate child level?

In MS Word I can select all the text, hit Shift F3 and it converts the text to All Lowercase, then if I hit Shift F3 again it will capitalize the first word in every sentence. Is there a way to do that with the radEditor?

Scheduler Localize Text

I need to localize "all day" and "Show 24 hours..." in the scheduler.

For "all day" I added the localization tag below. For "Show 24 hours..." I figured this line of code would do it. What am I missing?

rsScheduler.Localization.Show24Hours = (

string)_Master.m_FormLabels["Show 24 hours..."];

<telerik:RadScheduler ID="rsScheduler" runat="server" Skin="Office2009" EnableEmbeddedSkins="false"

DataKeyField="RecordID" DataStartField="StartDate" DataEndField="EndDate" DataSubjectField="Name"

Height="100%" Width="100%" OnNavigationCommand="rsScheduler_OnNavigationCommand" OnAppointmentDataBound="rsScheduler_AppointmentDataBound"

OnClientAppointmentDoubleClick="OnClientAppointmentDoubleClick" OnClientAppointmentInserting="OnClientAppointmentInserting" OnClientAppointmentCreated="OnClientAppointmentCreated" AllowDelete="false" AllowEdit="false" ShowDateHeaders="True" ShowNavigationPane="True" BorderStyle="NotSet" OverflowBehavior="Scroll">

<Localization AdvancedAllDayEvent="All day"></Localization>

</AppointmentTemplate>

</telerik:RadScheduler>

Page size not appearing after setting to maximum number of records

Hi,

Page Size is not appearing in grid footer after once user set the page size equal to maximum number of record. For example, if there are 600 total number of records and page size is initially set to 25 records per page, later when in run time user set it to 600 per page, then after that page size is not appearing to reset it back to 25 records per page.

Please suggest.

Regards,
Krunal

GridClientSelectColumn header chkbox

I have a radGrid that has a gridclientselectcolumn. The problem I am having is when I check the header check box, only the records on the current grid page are selected/deselected. I need to select/deselect "All" the records for the grid, irregardless of how many pages the grid contains. How do you do this from the server side code (vb - vs2008)
