ASCX: The control requires a ScriptManager on the page.

so far - completely unable to get telerik Q2 2009 to work in MVC projects using any sort of encapsulation with ascx files.

Trying to use a combo box inside a ascx that is rendered with Html.RenderPartial.

Is this possible? Or do all the rad controls have to go in the aspx views?

Using LINQ datasource and FormView

First I must say, thanks for this new addition, defintely a nice to have feature.

However I am having some issues with it when not used inside a RadGrid as a BinaryImageColumn.

I took my existing app that used pictures on the file system and changed it to use images in the database using BinaryImage. My datasources are all LINQ Data Sources. My SQL 2000 table has a photo column of type 'Image'. I am using a FormView that gets it data from my LINQ data source.
Looking at your example you use a SQL data source and I would guess that it returns the Image column as a byte[] but when using LINQ my image column comes back as System.Data.Linq.Binary. This causes a 'Specified cast is not valid' exception.
My first work around was to change my Linq definition of my image column to type Byte[] and all works well. Except in another part of my app I use a RadGrid and the BinaryImageColumn it fails to work there. I believe its the opposite issue that it's expecting the other type.
I would prefer to leave my LINQ definition to have the default Image column as a System.Data.Linq.Binary and deal with the casting issue.

Can someone tell me the syntax of how to cast between Byte[] and System.Data.Linq.Binary in the aspx page or do I have to do it in code behind?

Thanks,

Perry

Can you use <#%Eval fieldname%> with 2 datasources

Is it possible to have more then one datasource with the <#%Eval fieldname%> literal? I am using sql data source for a radgrid and I want to use another sql data source for a sub section underneath the radgrid in a lower hierarchy.

Format LabelAppearance

Hi. I use to have a RadChart that would appear on a masterpage. I now render the RadChart in a console application and save it to disk which works fine. The only thing is I can't seem to remove the label series or set the line series in the chart plot area. I think this is because unlike before, I haven't defined any ChartSeries items in my code behind. Here is my code:

    
            ArrayList myList = new ArrayList();  
        
            myList.Add(1);  
        
            myList.Add(2);  
        
            myList.Add(3);  
        
            myList.Add(4);  
        
            RadChart radChart = new RadChart();  
        
            // Some formatting here  
        
            radChart.DataSource = myList;  
        
            radChart.DataBind();  
        
            radChart.Save(@"c:\mychart.png", ImageFormat.Png);

This work fine. The following code doesn't work because I have no ChartSeries items:

    
            foreach (ChartSeries series in radChart.Series) {  
        
                series.Appearance.LabelAppearance.Visible = false;  
        
                series.Appearance.LineSeriesAppearance.Color = System.Drawing.Color.Black;  
        
            }

Is there any way around this? If I try to use ChartSeries items it returns an error because I'm working with a console application.

[Solved] More than one RadUpload on the page

Hi!

I have some problems when using RadUpload, for example:

<telerik:RadUpload ID="RadUpload1" runat="server" TargetPhysicalFolder="c:\\folder1\\"/>
<telerik:RadProgressArea id="RadProgressArea1" runat="server"/>
<asp:Button id="button1" runat="server" OnClick="btn1_Click" text="Submit" />

<telerik:RadUpload ID="RadUpload2" runat="server" TargetPhysicalFolder="c:\\folder2\\"/>
<telerik:RadProgressArea id="RadProgressArea2" runat="server"/>
<asp:Button id="button2" runat="server" OnClick="btn2_Click" text="Submit" />

If I select files both in RadUpload1 and RadUpload2, and click button1 to submit RadUpload1, files in RadUpload2 also will be uploaded?

It seems that doing postback will upload all files selected in RadUpload?

Do you have an easy way to make something like an independent upload group including a RadUpload, a RadProgressArea, and a submit button? I just wonder if there is something like this in RadUpload.

:) Thanks!

Best Regards
Airad

[Solved] Datepicker events?

Hi

I was just wondering if it is possible to somehow handle events from the datepicker that is embedded into scheduler in month view?

Basically, what I'm trying to do is capture the date that was selected, and then redirect based on that date, eg. If 18 July 2009 is picked, redirect to Calendar.aspx?date=20090718

How to migrate custom skins to Q1 2009 ?

We are using 2008.3.1125.35 build with plenty of custom skins.

Q1 2009 brakes almost all of our custom skins. I followed several threads (like http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/q1-skins.aspx) and looked at all the sticky threads about skins that you posted. I still do not see the answer on

1. How I can automatically convert my current skins to Q1 2009 skins?
2. If there is no way to convert automatically - can we pay for couple hours of your time, so you do the conversion?
3. Where is the guarantee that this disaster does not happen again?

Problem with grid appearance when exporting to excel and CommandItemTemplate

Hi

I have a grid that contains a command item template and this is disrupting the appearance of the grid when i export to excel.
There is no feature here to include a screenshot but basically the command item template is positioned in columns A and B of the grid and then the rest of teh grid is positioned below it but in columns C onwards.

The output looks like this

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
x Command item template
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
                                            xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
