Hi,
I am working on rad gridview for winforms. I have a grid with four columns. The first columns is an id field, second column a display field. The third column is a hidden field that has two possible values(lookup, user entry). Based on this the fourth column should show a drop down list or a text box. If the value of the third column is "lookup", we have to get the id value from the id column, query a table with the id and fill the drop down with the resultant values. If the value of the third column is "user entry", we have to show a text box there where user can enter values. Upto this i have done but the problem is, the text box seems to be in locked mode initially when tried to enter data in it. If we try to enter the data after clicking some other columns , then it works fine. I am listing the code below.
Please help me to solve this.

I am new to RadGrid for WinForm, and have some basic questions:
1. Upon adding a new row to the grid, I want to write the value in code in one of the 10 cells. I tried by writing this code in the RowChanged event but did not work: radGridView1.CurrentRow.Cells["WeekNumber"].Value = radSpin1.Value;
How I can achieve this.
2. I don't want to use spinbutton Editor with a Decimal type column. Please let me know how to change the default Column Editor of a Decimal Type column?

I have a RadForm Dialog that sometimes does some lengthy operations.
In this case, the Form does not always repaint, is that the expected behaviour?
Do I always have to implement some Worker Thread pattern when working with RadForm?

I have set images to my dockable document forms (UserDockForm based, imported as local resources) and they display nicely in the tab, but not in the drop down menu when the tab area is filled - which I think would be expected.
What am I missing?

Is there as way to get the RadRibbonbar to behave like the MS Ribbonbar? The RadRibbonbar appears to have only 2 modes (expanded and not expanded) and when expanded the RadRibonbar uses valuable screen space. The MS Ribbonbar appears to have a 3rd mode where when the RibbonBar is popped open (single click) as opposed to expanded (double click), and it overlays the underlying form and does not use any screen space.

Hello Telerik,
I've read the following post: http://www.telerik.com/community/forums/winforms/dock/fixed-size-dockpanels.aspx
It mentions that in the Q2 release something should be implemented having fixed size dock panels.
The following is what I require:
3 dockpanels:
[A]
---
[B]
---
[C]
The height of A and C should be fixed.
the height of B should be filling the remaining space.
How can this quest be accomplished?
Kind regards,
Jack

I am having trouble finding a solution to this need. I have a radTabStrip on a form with one tab created at Design time. This one tab is [Add New] used for adding other tabs. I need to respond to both Right Click (mousedown) and Double click on the Dynamically created tabs. This is no problem on the tab created at design time because it is easy to create the event but can't seem to create an event for the dynamic tabs.
The examples I found in the documentation (responding to right click and double click) only deal with design time tabs. When I use the mouse down and click events for the RadTabStrip itself it respond to clicks on more than just the tabs, but on the control itself.
Any help (guidance) would be appreciated.
I am using VB.net in VS2008.
BTW: Your controls are great!

Hello Telerik Team,
I'd like to know if it would be possible not to show repeated values for any given column when the data is ordered by dat column.
For example, suppose I need to provide a grid wich consist on customers data.
Each customer could have serveral adresses and several Phone Numbers per address.
A typical view for this information would be like this:
Cust. 1 -- Addr. 1-1 -- Phone1-1
Cust. 1 -- Addr. 1-2 -- Phone1-2
Cust. 1 -- Addr. 1-3 -- Phone1-3
Cust. 2 -- Addr. 2-1 -- Phone2-1
Cust. 2 -- Addr. 2-1 -- Phone2-2
in this case I would like to present it more like a tree:
Cust. 1 -- Addr. 1-1 -- Phone1-1
-- Addr. 1-2 -- Phone1-2
-- Addr. 1-3 -- Phone1-3
Cust. 2 -- Addr. 2-1 -- Phone2-1
-- Phone2-2
May be using a tree would be better but I want to use the filter row feature to look up for a customer by any property.
Is this possible? Do you recomend another control instead?
Best regards.
Gonzalo
