Hello,

 

So I am new to Telerik Winform. I had amazing experience using Telerik. But what I still don't get it is how to use the RadLayoutControl.

As far as my understanding, RadLayoutControl provide a customize layout template design method completed by user drag and drop controls on the LayoutControl object (what I called layer 1).

My questions is when I wanted to place a control on top of a control that already top of a Layout control(which I called layer 2), system treat my intention as I want to place another Layer 2 control which I wanted that control to be placed on layer (e.g. place a control on collapsible panel).

Do I misunderstand the purpose of layoutcontrol?

 

Sorry for my bad english.

Since upgrading to Q3 SP1 I'm getting an error trying to use the BestFitColumns method on the GridView. What worked great on Q3 is now giving me an ArgumentOutOfRange exception.

Error Message is "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

Thank you,

Hi,

I have a radgridview that is populated with data via a LINQ query.

LINQ returns an async list and if it is not a null list the datasource of the grid is set.

After the grid is populated I want to be able to grab multiple rows in it (perhaps by holding CTL) and then drag these rows into another grid / control.

I have got this to work on a grid populated with simple data via a loop. I can't get it to drag when it has a datasource set.

Can anyone help?

Thanks,
Martin.

HOW TO PASS THE VALUES TO THE CELLCLICK EVENT

Hello Support,

  I am using  Telerik for Winforms version "2015.2.728.40" and have discovered an issue in that the Selected item in a CommandBarDropDownList displays but appears to be cleared from the object after minimizing the window.

Attached is a sample project to reproduce this error(Please change the extension back to zip).  To reproduce, run the application and then click on the button on the toolbar, this should work and display a message.  Now minimize the form, then maximize.  Click the button on the toolbar again.  You should now see an error.

I have not tested this issue on the most recent version of the Telerik library, but I may do that next.  My project is very far along and would prefer to leave it at the older version if possible.

Thanks

Francisco

Hello,

Is it possible or is there any way to access radMultiColumnComboBox search cell programmatically in C#?

 

     Hi there,

 

I saw the demo here: http://demos.telerik.com/aspnet-ajax/scheduler/examples/resourceavailability/defaultcs.aspx?skin=Telerik.

 

I wish to achieve something similar in Windows Forms. How to achieve this? Please guide.

Thanks.

Hello,

I'm on Progress OpenEdge 11.6.2.

Ich have a Gridview with about 1000 Adress rows. I create a new Adress outside the Grid and create via Datasource a new Row (at the end of the list) in the Grid.

I walk through the Rows an select the new row with "IsSelected = true". Everything works fine.

Only the Grid do not scroll to the selected row. So I have manually to scroll down to see this row. I tried "IsCurrent" with the same result.

Is there a way that the Grid autom. scoll down to selected row?

Thank you for your answer.

Regards Jürgen

I've 2 questions:

First one:

I've a problem with custom Style definition. I want to edit some of built-in styles. At this moment I've got this code:

StyleDefinition h1 = this.radRichTextEditor1.Document.StyleRepository.GetValueOrNull(RadDocumentDefaultStyles.GetHeadingStyleNameByIndex(1));
h1.SpanProperties.FontSize = ConstDocumentationParams.fontSizeH1;
h1.SpanProperties.ForeColor = System.Drawing.ColorTranslator.FromHtml(ConstDocumentationParams.colorH1);
h1.SpanProperties.FontStyle = ConstDocumentationParams.typeH1;
h1.SpanProperties.FontWeight = Telerik.WinControls.RichTextEditor.UI.FontWeights.Normal;
h1.SpanProperties.FontFamily = new Telerik.WinControls.RichTextEditor.UI.FontFamily(ConstDocumentationParams.fontFamily);

 

Everything works fine until I select text and click the heading edited by me. Text changes to old style, not new. How can I fix this problem?

 

Second one:

How can I insert programmatically some element whitch will be generated to html tag: "<h1>","<h2>" etc.

 

Best regards

Marcin
