Grouping, Exporting, and Refreshing not working
I have the following code.  When I try to group, refresh ("Restore Defaults"), or Export, nothing happens.  How do I make these events work?

ASPX Code
<telerik:RadGrid ID="RadGrid1" runat="server">
</Telerik:RadGrid>

ASPX.CS Code
protected override void OnInit(EventArgs e)

rad grid filtering is not working on tab key press first time
I have a radgrid and have enabled filtering. I have restricted the filtering to "startswith" only. The problem is that when I enter in some filter text it fires the ItemCommand event which is fine but, it does not filter the grid. If I re-type the filter string again it fires the ItemCommand event again and the second time and any more subsequent attempts work as expected resulting in the grid being filtered. This is so wierd and I have no idea whi I have to type in a filter string twice to get it to work.

X Axis Rotate Angle isn't normal
If you set the rotation angle in the X Axis, the text will render, apparently rotated around the center of the text.

<XAxis DataLabelsField="IncidentType">
    <LabelsAppearance DataFormatString="{0}" RotationAngle="60">
    </LabelsAppearance>
    <TitleAppearance Text="Incident Type"></TitleAppearance>
</XAxis>

I've used a lot of different chart controls in Windows and web development, and this is the first time I've seen this.  Normally, the label text on the x axis would be rotated with the pivot point being the first letter.  That way, the beginning of the text is still centered underneath the column it goes with.  Now the text looks like it is off, and you have to widen your chart to see that the pivot point of the rotation is the center of the text, not the left edge. 
Can this get fixed?  Or at least give us the option for how we want to rotate the text. 

Thanks

Dyamic Footer Total Error
Hi,

We are using latest Radgrid in our asp.net application. I need to provide user a textbox to enter amounts into for each account. I need to show total amount entered by user for all accounts in footer. For this I am using template column with RadNumeric textbox like this:

<

 

 

telerik:GridTemplateColumn AllowFiltering="False" FilterControlAltText="Filter Amount column" Groupable="False" HeaderText="Amount" Reorderable="False" ShowFilterIcon="False" UniqueName="Amount" HeaderTooltip="Amount">

 

 

 

<HeaderStyle Width="17%"></HeaderStyle>

 

 

 

<ItemTemplate>

 

 

 

<telerik:RadNumericTextBox ID="txtAmount" runat="server"

 

 

 

Type="Currency" Width="75%" CssClass="rightalign">

 

 

 

<ClientEvents OnBlur="Blur" OnFocus="Focus" />

 

 

 

</telerik:RadNumericTextBox>

 

 

 

</ItemTemplate>

 

 

 

<FooterTemplate>

 

 

 

<asp:Literal ID="Literal1" runat="server" Text="Sum"></asp:Literal>

 

 

 

<telerik:RadNumericTextBox ID="txtAmountTotal" runat="server" Type="Currency">

 

 

 

<ClientEvents OnLoad="Load" />

 

 

 

</telerik:RadNumericTextBox>

 

 

 

</FooterTemplate>

 

 

 

</telerik:GridTemplateColumn>

 


As suggested in the link:
http://www.telerik.com/community/code-library/aspnet-ajax/general/refresh-footer-values-in-radgrid-client-side-using-radnumerictextbox.aspx

I have code in java script.
When I run my app and enter into textbox,

function

 

 

Focus(sender, args)

 

{

tempValue = sumInput.GetValue() - sender.GetValue();

}


gets called and I get an error on this line saying that 'Object doesn't support property or method 'GetValue''. I am not sure where it is going wrong.

I am not using 'NeedDataSourceEvent' because my application is complicated and we bind the grid when ever it is required.

Thanks,
Prathiba

I don't know what exactly can be wrong because I reviewed my code it seems all looks quite good. Also I used same functionality with RadControls for asp.net it working good, and when migrated to the RadControls for ASPNET AJAX I encountered with such problems in forms where used rad ajax. And in some scenariuos it works fine, but sometimes crashes hard to predict when and why it crashes.
So maybe you could help me with that problem.
I can only copy code of one of my forms where I getting exception, because whole system is hudge enough. I am using ms web clint factory for client and for services web service factory. Is it can affet somehow ajax ?
So here it is code of one form:
Aspnet:

[Solved] Can't Find Rad Button Inside Rad Combo Header Template That Is Inside A User Control
Hi,

I have a rad button that is inside the header template of a rad combo and the rad combo is in a user control.  I am trying to change the selectedToggleState of the rad button when an item is clicked client side.  I am attaching a javascript function to the Item Clicked event of the combo box in code behind and sending the client id of the button that is inside the header template to the function,  but when I try to access the button in the client side script it always returns null.  I placed an alert inside the client side script to show the client id of the button and it seems to return the correct value, but when I try to access the button it always returns null.  I have tried several methods to find the button but none have worked.
Below is my code.

User Control page combo box on it.
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="UC Combo.ascx.vb" Inherits="IPS_Gateway.UC_Combo" %>
 
<script type="text/javascript">
    function pageLoad() {

    function ShowHideList(sender, args) {
        toggleList = sender.get_selectedToggleStateIndex();
        switch (toggleList) {
            case 0:
            alert('0');
                break;
            case 1:
                alert('1');
                break;
            case 2:
                alert('2');
                break;
        }
    }
 
    function ComboItemChecked(strClientIds, args) {
        var item = args.get_item()
        var itemText = item.get_text();
        var aryClientIds = strClientIds.split(",");
        var cmbField = $find(aryClientIds[0]);
        var hdfSelectedCount = document.getElementById(aryClientIds[1]);
        var hdfSelectedValue = document.getElementById(aryClientIds[3]);
        var hdfSelectedText = document.getElementById(aryClientIds[2]);
        var hdfCheckedIndex = document.getElementById(aryClientIds[4]);
        alert(aryClientIds[5]);
        //   var ibtDisplay = document.getElementById(aryClientIds[5]);
        //    var ibtDisplay = $find(aryClientIds[5]);
        var ibtDisplay = $telerik.findButton(aryClientIds[5]);
