I have a Radgrid with a RadNumericTextBox in a template column. The OnValueChanged event passes the value to the Javascript function. How do I also pass the value of the Price column of the same row in the same OnValueChanged event?
<script type="text/javascript">
function Total(sender, eventArgs) {
var total = $find('<%=tbTotal.ClientID %>');
var OldTotal = total.get_value();
var i = eventArgs.get_newValue();
var i2 = eventArgs.get_oldValue();
total.set_value(i + OldTotal - i2);
}
<script type="text/javascript">
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" >
<MasterTableView datakeynames="Item"
datasourceid="SqlDataSource1" ClientDataKeyNames="Quantity,Price" >
<Columns>
<telerik:GridBoundColumn DataField="Item"
UniqueName="Item">
</telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="TemplateColumn" >
<ItemTemplate>
<telerik:RadNumericTextBox ID="tbQuantity" Runat="server"
ShowSpinButtons = "true"
dbValue='<%#Bind("Quantity") %>' >
<ClientEvents OnValueChanged="Total" />
</telerik:RadNumericTextBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridBoundColumn DataField="Price"
UniqueName="Price">
</telerik:GridBoundColumn>
</Columns>

I'm sure the answer is something simple. I am trying to set my chart's legend cursor (mouse pointer) to "default" after the chart has already been created. I can't seem to figure out the correct syntax. Your help will be greatly appreciated.Thanks in advance.
var radHtmlChartObject = $find("<%=RadHtmlChart1.ClientID %>"); //the standard control object
var kendoChart = radHtmlChartObject.get_kendoWidget(); //the Kendo widget
//Examples that work correctly
kendoChart.options.legend.position = "top";
kendoChart.options.legend.labels.background = "green";
//None of these work for me:
kendoChart.options.legend.item.cursor = "default";
kendoChart.options.legend.item.cursor.style = "default";
kendoChart.options.legend.item[0].cursor = "default";
kendoChart.options.legend.item[0].cursor.style = "default";
kendoChart.options.legend.items.cursor = "default";
kendoChart.options.legend.items.cursor.style = "default";

I am using RadFilter to filter results in a RadGrid. For whatever reason, it will not filter my results in the rad grid. If I used the asp Grid option though, it does work. Is there a setting I am missing? Pictures attatched show that I should be getting results when I filter for cartoon, using the RadGrid and RadFilter, but nothing comes up.
My code is as follows: (didn't give filter or grid ID names, I am just trying to get it to work at the moment.)
<telerik:RadFilter ID="RadFilter1" runat="server" FilterContainerID="RadGrid1">
</telerik:RadFilter>
<br />
<br />
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="ListViewFilter" Height="80px">
<GroupingSettings CollapseAllTooltip="Collapse all groups"></GroupingSettings>
<MasterTableView AutoGenerateColumns="False" DataSourceID="ListViewFilter">
<Columns>
<telerik:GridBoundColumn DataField="EE" FilterControlAltText="Filter EE column" HeaderText="EE" SortExpression="EE" UniqueName="EE">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Interest" FilterControlAltText="Filter Interest column" HeaderText="Interest" SortExpression="Interest" UniqueName="Interest">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Like_or_Dislike" FilterControlAltText="Filter Like_or_Dislike column" HeaderText="Like_or_Dislike" ReadOnly="True" SortExpression="Like_or_Dislike" UniqueName="Like_or_Dislike">
</telerik:GridBoundColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>

Hello,
on my pages where i use RadAjaxPanel, RadAjaxLoadingPanel, RadGrid, RadPanelBar, RadComboBox, RadMenu and RadScriptManager sometimes i got the following script error:
Sys.ScriptLoadFailedException: The script '/Telerik.Web.UI.WebRessource.axd?_TSM_HiddenField_=ctl00_ScriptManager1_HiddenField&compress=1 .......... could not be loaded.
I'am using ASP .NET 2.0 and RadControls for ASP.NET AJAX 2009.2.701.20. I read about this problem in an other thread but it was for an much older version of the RadControls. So what should i do to solve this problem?

I am using ASP.NET 2.0 in VS2008 using telerik AJAX Q3 2008.
I am using a page with several Telerik controls including RadWindow RadGrid etc. RadTextBox rad ToolTip
when I call txtBox.Focus from the server side where txtBox is a RadTextBox I get the error
Sys.ScriptLoadFailedException. The script /Script.Resource.Axd could not be loaded.
What is up?
If I don't call the Focus() method of the RadTextBox I do not get the javascript error.
