Self referencing RadGrid's GridTemplateColumn displays values twice if it has both UniqueName attribute and ItemTemplate tag
Hi,
I have a RadGrid which has NestedHierarchy set up. I also have edit functionality associated to grid rows.

<Columns>
    <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" EditText="Rename Favourite" HeaderStyle-Width="15px">
        <ItemStyle CssClass="edit-grid-controls" />
    </telerik:GridEditCommandColumn>
    <telerik:GridTemplateColumn HeaderText="Name" UniqueName="Name">
        <ItemTemplate> <%# Eval("Name") %> </ItemTemplate>
        <EditItemTemplate><asp:TextBox ID="txtFavouriteName" runat="server" Text='<%# Eval("Name") %>' Width="100%" MaxLength="256" />
        </EditItemTemplate>
    </telerik:GridTemplateColumn>
    ... more columns ...
</Columns>

1. Since the time this grid was converted to a nested self referencing hierarchy table, the Name is displayed twice!
2. If I remove UniqueName attribute, the data wont show up.
3. If I remove ItemTemplate, things are fine until I attempt for an edit thru "GridEditCommandColumn".
4. Please have a look at the attached images. Image ending with right is for "normal" radgrid. Image ending with "wrong" is for nested hierarchy grid. When in edit mode, I don't want to display values twice.

Confirm appointment insert
So I'm trying to use a RadWindowManager in conjuction with an appointment insert. So far I have the following:

VB Code-Behind:
Protected Sub RadScheduler1_AppointmentInsert(sender As Object, e As Telerik.Web.UI.AppointmentInsertEventArgs) Handles RadScheduler1.AppointmentInsert
            RadWindowManager1.RadConfirm("Server radconfirm: Are you sure?", "confirmCallBackFn", 330, 100, Nothing, "Server RadConfirm", Nothing)
End Sub

Javascript functions:
<script type="text/javascript">
    function schedulerFormCreated() {
            $telerik.$(".rsRecurrenceOptionList li:eq(4)").hide(); 
    }
      
        function confirmCallBackFn(arg)
    {
         return arg;
    }
      
    function OnClientAppointmentInserting(sender, eventArgs)
  {
    if(confirmCallBackFn())
        {
         eventArgs.set_cancel(false);
        }       
            else { eventArgs.set_cancel(true);
        }
  }
  
</script>

The problem I seem to be having is that the radconfirmation window isn't even being called upon appointment insert, therefore the javascript function is returning a null or undefined value. If the radconfirm is not even being displayed, I can't pass the true or false value on to the inserting client event in order to go ahead and insert or cancel the insert. Anybody have any insight or have a working version of this? Any help would be greatly appreciated!

New lines content in IE and Chrome
Hi,

We have noticed the following behaviour:
Scenario:
1) Set the new line mode to paragraph
2) Enter some line, for example "First Line", and press Enter
3) Go to HTML view
Perform this actions in IE and Chrome.
HTML view in IE:
<p>New Line</p>
<p>&nbsp;</p>
HTML view in Chrome:
<p>New Line</p>
<p><br />
</p>

Why is the mark-up different in this browsers? Is this the expected behaviour or such kind of a bug?

Best regards,
Roman

[Solved] RadNumericTextBox Set Value
Hi guys, I was hoping you could provide some advice on setting the value of a RadNumericTextBox.

I have another control (dropdown) that when changed needs to update the RadNumericTextBox.

The javascript is firing and returning the current value as per below.

var txtTypeSelected = window["<%=txtOffsetPeriod2.ClientID %>"];
alert(txtTypeSelected.value);

However when I then try to set a new value this doesn't appear on screen as the control has had its id set as txtOffsetPeriod2_text.

txtTypeSelected.value = 1;

Is there another way I can set the RadNumericTextBox value when the function is called by another controls change event?

Thanks for the help.

[Solved] Chart only showing the first 8 items
This is my first time trying out RadChart. I have a very simple chart (that followed the example in the documentation section):

<telerik:RadChart ID="RadChart1" runat="server" DefaultType="Line" />

The code behind does a simple database query:

SqlDataSource sqlDataSource = new SqlDataSource();
sqlDataSource.ID = "myDataSource";
sqlDataSource.ConnectionString = "<snip>";
sqlDataSource.SelectCommand = "select convert(varchar(10),SearchDate,101) as SearchDate, AverageSoldPrice from SearchResult where SearchId = 1 order by SearchDate";
this.Page.Controls.Add(sqlDataSource);
RadChart1.DataSourceID = "myDataSource";
RadChart1.Series[0].DataYColumn = "AverageSoldPrice";
RadChart1.PlotArea.XAxis.DataLabelsColumn = "SearchDate";
RadChart1.DataBind();

If I execute that line in the database, I get 30 rows back. However, when the chart is created, I only have the first 8 items shown, labeled 0 through 7. Why are the others missing, and how can I get the actually dates to be displayed?
