Hi,
I am creating a dynamic form and after adding dynamic controls but i receive this message (" The best overloaded method match for 'System.Windows.Forms.Control.ControlCollection.Add(System.Windows.Forms.Control)' has some invalid arguments ")
and (" cannot convert from 'Telerik.WinControls.UI.RadGroupBox' to 'System.Windows.Forms.Control' ")

Here is the code:

Form frm = new Form();

RadGroupBox groupb = new RadGroupBox();

Memory Leaks

Hello,
We have a problem using the telerik controls on a form, a memory occupied problem, but never freed, the form uses the following controls:
• 3 DataTable.
• 1 DataSet.
One of the DataTable is populated with 10,000 records and the other 2 with 5 records, more records DataTable is populated as follows:

dtDataTable.Add("Ide", typeof(int));

dtDataTable.Columns.Add(

"Nom", typeof(string));

foreach (Objeto oObjeto in ArrayObjetos)

{

DataRow drRow = dtDataTable.NewRow();

drRow [

"Ide"] = oObjeto .Ide;

drRow [

"Nom"] = oObjeto.Name + " " + oObjeto.LastName;
dtDataTable.Rows.Add(drRow );

}

The 15 MB memory increases by this load but the release (close) is in use 8 MB of those 15.
The Close () the form we make the following:

if(dtDataTable != null)

dtDataTable.Clear();

dtDataTable=

null;

if(dtDataTable1 != null)

dtDataTable1.Clear();

dtDataTable1=

null;

if(dtDataTable2 != null)

dtDataTable2.Clear();

dtDataTable2=

null;

The question is, We are releasing resources correctly or the problem may be the way I'm filling?
Thank you very much.

is in use 8 MB of those 15.The Close () the form we make the following:if;if;if;

Border & backgroundcolor RadScrollablePanel

I'm using the RadScrollablePanel in a DocumentWindow to have themable scrollbars when the content doesn't fit. Afaik the scrollbars of the DocumentWindow aren't themeable (yet).

Is it possible to have the panel to be "invisible", that is: disable border and backgroundcolor equal to the background color of the DocumentWindow?

Enums and Combobox

Hi,

What happen with the gridview and enums on the last release?
I've been using an custome made localized enum converter to convert my enums to the correct language.
I've used one of the gridcolumns to view this enum, but now (with the latest release) i get an converter error : "EnumConverter cannot convert from Jobmatch.EntityFramework.Entities.WorkdayTypeEnum."

This is the article i used when i created the LocalizedEnumConverter. http://www.codeproject.com/KB/cs/LocalizingEnums.aspx?msg=2281102

As i said, this worked nicely in the previous version of the GridView.

Regards
Svein Thomas

ShowItemCloseButton and preventing docking

I am putting my menu in a left side dock.

I would like to prevent them from closing this panel and prevent them from docking it to the top or the bottom.

ShowItemCloseButton is set to false...but the x is still there and they can close it...not sure what I am doing wrong there.

I can't find anything on the designer that would allow me to set which positions are allowed/not allowed.

Help!

Thanks,
David

[Solved] RadGridView with titlebar

Hi All,

is it possible to make/show a titlebar for the radgridview (like the titlebar of the forms)?
Every grid has a text property, but, as far as I know, that is invisible on the grid controls.

Regards,

Peter

2011 Q2 drag and drop with ALT key is not working?

Hi,

I am trying to implement the "copy" scenario of drag and drop using RadTreeView.
And I found a thread which mentioned that dragging with ALT key pressed will clone the node to the other RadTreeView control.
However, I can not make it happen either in my own project or in the demo project.
Is this feature broken or I missed somthing?

thanks.
