odd grid height issue in Firefox

I have a grid which is set to 100% height. The grid displays search results. When a user clicks on the "find" button, the results are loaded in the grid. In IE (9), the grid appears correctly. In Firefox (15), there is a vertical space of about 125px below the grid pager and the grid doesn't extend all the way down to the bottom of its container. If the user clicks on "search" a second time, the grid extends properly. I have attached two screen captures demonstrating what it looks like in ie (correct) and firefox (incorrect). I have added a panel with colored background as a container for the grid so you can see it appears to be the grid which is not extending and not the container. This effect occurs even if I do not include this panel. My markup is below.

<asp:Panel id="pnlSR" runat="Server" Height="100%" style="padding:5px; background-color:Red;">

RadGrid GridButtonColumn

How do I work with the RadGrid GridButtonColumn if in case I want to use the button to edit a record? I have not seen any documentation as far as this control is concerned, can somebody point me in the right direction as far as programming a datasource with this control?
Thank you!

Why is my itemcontrol not firing... strange!

I have a strange problem. I am using a UserControl (say UserControlA) that has a RadGrid on it which is inside another UserControl (say UserControlB) that is Ajax enabled with RadAjax. So it looks like this:

Page > UserControlB (Ajax Enabled) > UserControlA > RadGrid

On a test page this works fine with the ItemCommand of RadGrid firing properly.

Now when I put the UserControlB in my final page (that has many other controls), the ItemCommand of the RadGrid does not fire at all! The funny thing is that this page has many other usercontrols that has its own grid which fires just fine!

So, the only thing I can think of is the Ajax Enabled UserControlB.

The ItemCommand is used in the straignt forward way:

...

<telerik:GridTemplateColumn HeaderText="Actions">

<ItemTemplate>

<asp:Panel id="iconsPanel" runat="server" Visible="<%# IsActionVisible() %>">

<asp:ImageButton ID="btnDelete" runat="server"ImageUrl="~/images/icons/Small/delete.gif"

ToolTip="Delete Document" CommandName="Delete" />

</asp:Panel>

</ItemTemplate>

</telerik:GridTemplateColumn>

...

Then I am using normal DataSource() and DataBind()

finally the ItemCommand is created as:

private void InitializeComponent()

{

this.Init += new System.EventHandler(this.Page_Init);

this.Load += new System.EventHandler(this.Page_Load);

grdDocuments.ItemCreated += newTelerik.Web.UI.GridItemEventHandler(grdDocuments_ItemCreated);

grdDocuments.ItemDataBound += newGridItemEventHandler(grdDocuments_ItemDataBound);

grdDocuments.ItemCommand += newGridCommandEventHandler(grdDocuments_ItemCommand);

}

Any ideas on how to proceed? I am running out of options, tried many things but nothing worked!

            function ValueChanged(sender, eventArgs) 
        
            { 
        
                 alert(sender.testAtrb); 
        
                 alert(sender.get_element().testAtrb); 
        
                 alert(sender.get_element().getAttribute("testAtrb"));

Pie chart graphics is not shown

Hi, I'm working on an app asp.net and using radchart control in it, I wrote the next test code:

HTML

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<div>

<telerik:RadChart ID="chrChart" runat="server" >

<PlotArea>

<EmptySeriesMessage Visible="True">

<Appearance Visible="True">

</Appearance>

</EmptySeriesMessage>

</PlotArea>

</telerik:RadChart>

</div>

</form>

vb.net code

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

chrChart.Clear()

chrChart.AutoLayout = True

chrChart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Font = New Font("Arial", 10)

chrChart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Color = Color.Black

chrChart.PlotArea.XAxis.AutoScale = False

Dim loDataSeries As New ChartSeries("Chart test", ChartSeriesType.Bar)

loDataSeries.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels

Dim myItem1 As New ChartSeriesItem(10, "myitem1")

myItem1.Name = "myitem1"

Dim myItem2 As New ChartSeriesItem(20, "myitem2")

myItem2.Name = "myitem2"

loDataSeries.AddItem(myItem1)

loDataSeries.AddItem(myItem2)

chrChart.AddChartSeries(loDataSeries)

End Sub

this code showed the bar chart correctly, but When I changed the ChartSeriesType to Pie, the graphics is not shown, (see image attached).

Dim loDataSeries As New ChartSeries("Chart test", ChartSeriesType.PIE)

When I comment the next code:

'chrChart.PlotArea.XAxis.AutoScale = False

I get the next exception

Unable to cast object of type 'Telerik.Charting.ChartXAxis' to type 'Telerik.Charting.ChartYAxis'.

regardless if the ChartSeriesType is Bar or Pie, I get the error.

What am I doing wrong?
