I have following paragraphs defined.

    
            <paragraphs> 
        
                <paragraph name="Normal" value="&lt;p&gt;" /> 
        
                <paragraph name="&lt;h6&gt;Local header&lt;/h6&gt;" value="&lt;h6&gt;" /> 
        
            </paragraphs>

In the dropdown the choices Normal and "Local header" is displayed, but when you select a "local header" (h6) element in the editor the text "Heading 6" is displayed in the dropdown. How can make so the text "Local header" is displayed instead?

ScriptManager giving object reference error

I have a new page using the RAD listboxes, when I place the RAD scriptmanager on the page and navigate to it, I recieve an object reference not set to an instance error message. I am running telerik version 2009.3.1103.35. If I replace the rad script manager with a regular script manager the error stops but none of the skins are working correctly.

Using a SQL-Datasource to populate the Rotator

Hi,

I'm having a problem populating my Rad Rotator using the traditional way of using a datasource in the ASP side of the code, this is what my code looks like.

    
            <telerik:RadRotator runat="server" ID="RadRotator1" RotatorType="AutomaticAdvance" ScrollDirection="Up" FrameDuration="7000" 
        
                    DataSourceID="SqlDataSource1">  
        
                <Items> 
        
                    <telerik:RadRotatorItem> 
        
                        <ItemTemplate> 
        
                            <asp:Image ID="imgAdBanner" runat="server" ImageUrl='<%# "~/ImageFilePath/" & Eval("ImageName") %>' 

                                    NavigateUrl='<%# Eval("LinkUrl") %>'  AlternateText='<%# Eval("AltText") %>' />
        
                        </ItemTemplate> 
        
                    </telerik:RadRotatorItem> 
        
                </Items> 
        
            </telerik:RadRotator> 
        
            <asp:SqlDataSource runat="server" ID="SqlDataSource1" 
        
                ConnectionString="<%$ ConnectionStrings : CS %>" 
        
                SelectCommand="SELECT ImageName, LinkUrl, AltText FROM RotatorImages">  
        
            </asp:SqlDataSource>

Any advice will be greatly appreciated.

How to get the selected Page Index?

Hi,

I have one grid which contains around 150 records. I have Edit Case button. Initially I have set the Page Size of the grid as 10. User can change the page size and will select some 100th record and clicks on Edit case button.
I need to display the selected case details and also need to reduce the page size of the grid from 10 (Or user selected page size) to 5 and wherever the 100th record exists (i.e in any page) that needs to be highlighted. Is this possible in the RadGrid?

Regards,
Medac

DataLabelsColumn for numeric values?

Is there a way to establish the datalabelscolumn for a numeric column?

I am returning 3 columns from a stored procedure. Column 1 is weekname and has values 1-52 in rotating order, the other two are the series data.

DataLabelsColumn is being set in page.load as:

rctrend.PlotArea.XAxis.DataLabelsColumn = "weekname"

If from the stored procedure, I do this: Select [weekname] as weekname
I get 3 series in my chart and the datalabelscolumn directive is ignored.

If from the stored procedure, I do this: Select convert(varchar(10),[weekname]) as weekname
or SELECT convert(text, convert(varchar(10),[weekname]) )) as weekname
I get 3 series in my chart and the datalabelscolumn directive is ignored.

If from the stored procedure, I do this: SELECT 'w ' + convert(varchar(10), [weekname]) as weekname
DataLabelsColumn is respected and I get 2 series.

Whole routine is below:

    
                Private Sub MakeGraph()  
        
                    If Not IsPostBack Then  
        
                        rctrend.Chart.PlotArea.YAxis.AutoScale = True 
        
                        rctrend.PlotArea.YAxis.AutoScale = True 
        
                        rctrend.PlotArea.YAxis.IsZeroBased = False 
        
                        rctrend.PlotArea.XAxis.DataLabelsColumn = "weekname" 
        
                    End If  
        
                    rctrend.ChartTitle.TextBlock.Text = "Something" 
        
                    rctrend.DataSource = gensql.Get52WeekGraph  
        
                    rctrend.DataBind()  
        
                    If Not IsPostBack Then  
        
                        rctrend.Series(0).Appearance.ShowLabels = False 
        
                        rctrend.Series(1).Appearance.ShowLabels = False 
        
                    End If

                    }

I am getting error in line 6:
"GridEditFormInsertItem insertedItem = (GridEditFormInsertItem)e.Item;"

I have implemented Update and Delete methods similarly from Command Item Template, they seem to work fine. Just Insert is giving me this particular error.
But if i use the "Insert" button that comes by default in edit form, it is working fine.

I hope this information is sufficient. I you need further information please do let me know.

P.S : I have seen a few other suggestions in the forum saying to remove
AllowAutomaticUpdates="true", AllowAutomaticInserts="true". I have removed all of them.
