I am having a problem with the RadGridView when setting the datasource to null.
I have to dynamically generate a table I use for datasource. As I add or subtract columns everything seems to be working. The problem comes when I remove the last displayed column, the view still shows the column with all the rows. Although if I click a row I get a RowNotInTableException. Am I doing something wrong?
The pertinent code is :

The pertinent code is :
dataGridView1.GridElement.BeginUpdate();
dataGridView1.DataSource = CalculateTable(...);
dataGridView1.GridElement.EndUpdate();
The CalculateTable method returns null if there is nothing to do. Should I return an empty table instead, or is it some update thing I am not doing?

AutoSize is set to true on my RadPanel. The AutoScrollMinSize does not shrink even if I set the MinSize to 0 because the underlying controls are wider than the I would like to know if it is possible to hide the Horizontal Scrollbar even if the underlying controls are too wide. I still want to have the Vertical Scrollbar enabled/visible. Does the RadPanel have a function that would allow me to disable the Horizontal ScrollBar?
Thanks.
Dennis

Open the WinControls examples application and then choose to view the TAB Drag & Drop example for TabStrip WinControl.
Perform a drag and drop.
Expected behaviour is that control that is dragged is placed at location indicated by the drop hint location.
Instead the dragged control is placed at new location but additionaly the control at the drop location is swapped with original location of dragged tab?!
This behaviour was working properly in older version of WinControls. We are seeing this error for the first time with Q3 release.

I need to create WinForm where I will rotate data separated by columns, and which will allow user to do sorting. Ideally I would rotate content of RADGridView. Is it possible?

Hey all,
I am using RadRibbonBar inside my windows application. I want to know if I can swap two tabs locations in runtime. i.e I have tab1 as the first tab in my RibbonBar and tab2 as the second tab in my RibbonBar, what I want to do is to change the tabs locations and to make tab1 as the second tab and tab2 as the first tab in the RibbonBar using a Button click event in runtime. Is this functionality available?
Thanks in advance

Hi,
I am finding more basic issues with the RadRibbonBar.
Please consider the following code:
Notice the try {} blocks? Well I have to do that, otherwise a NullReferenceException is thrown on both methods. Bizarrely, the image setting works, even though the exception was thrown. I've previously seen this when setting the colour of a contextual tab group.
Any progress on automatically setting (or even programmatically being able to do it) the first contextual tab when a contextual tab appears?

Please consider the following code:

| radMenuItem.Click += new EventHandler(radMenuItem_Click); | |

| RadMenuItem radSubMenuItem = new RadMenuItem("Web Site Content"); | |

Will future releases of the Telerik controls allow binary serialization of their collections and items making those collections.
Currently neither items nor item collections of any of the controls i've used
seem to be marked for serialization. Binary serialization allows a more
complete form of data persistence as well as allowing developers to add
customisation that we may need to our own serialization in addition to that.
The current xml serialization does not allow for any customisation and also
lacks a considerable number of object parameters that it currently serializes.
Could future releases pls allow nodes/node collections , listbox items and collections , combobox items and collections and all other control items and their collections to be marked for serialization.

I didn't want to hijack this other thread, but as it talks about performance it is related:
http://www.telerik.com/community/forums/thread/b311D-bbbmem.aspx
In that thread you state that you are reworking the gridview for better performance and we should see something in the next release (2008 Q1?).
For the most part the gridview performance isn't that bad in my project, but one area it is extremely poor is using the BestFit() method on a column. I like to present a stylish output to the user and with dynamic data drawn from the database it is pure guessing to set the columns to a defined width. So after assigning a datasource, I loop over the columns and call BestFit(). This is very slow. I've taken to only doing it to a few key columns, but it would be nice to have the whole grid formatted nicely.
I just wanted to make sure improving performance of this method was part of the plan for the reworking of this control.
Thanks,
Alex

I have a gridview bound to a BindingSource bound to a typed DataSet, with the member specified as one of my DataTables
.
I've updated the SQL for the dataset, but when I add columns to the gridview, I don't see those new columns in the DataField dropdown. Even if I type in the name of the field to bind to, the column is empty.
What do I need to do?
