I need to get the splitter width for all the windows in a raddock to default to a bigger area.
I tried editing the UI element tree from the smart tag and even tried it in code

((

Telerik.WinControls.UI.SplitterElement)(this.dockMain.GetChildAt(1).GetChildAt(0))).AutoSize = false;

 

((

Telerik.WinControls.UI.SplitterElement)(this.dockMain.GetChildAt(1).GetChildAt(0))).SplitterWidth = 15;

 

however although I get no exceptions , my splitter widths remain the default width.
Is there a different property that needs to be applied to change the splitter width ?

I am trying to use the property builder to add colums and their headers in the latest Telrik WinControls and either the property builder close while doing this or when i click to add a new colum it closes down without saving. I therefore can't save any new colums using the property builder.

Has anyone else encountered this?

Hey everyone, hope you can help with this request because I don't know how to quite word it correctly, but I'm going to try my best.

I'm wondering if there is a way to code the combo box so that when a user selectes a value...and the box closes again, If you reopen the box, the selected value is either at the top or bottom of the list?  

for example lets say your drop down contains the following:

1
2
3 Selected Value
.
.
.
.
20

And then you select 3.   The drop down will close with that value selected, and then if you click to drop down again, your list now looks like this:


3 Selected Value
4
5
6
7
8
.
.
.


Same in reverse, so like if 6 was selected, then it would look like this:

1
2
3
4
5
6 selected value.


I hope that kinda makes sense.

Thanks.

Hello,

Using Q1 2009 Demos...  
When we add a new row to the  child grid, the same value is updated in the last row.
When I click the right button on that row, an error appears.

Hey everyone.

I am upgrading my skills into winform development from asp.net and need a little help....I think asp.net is much easier when it comes to grids and data layout....but hey its only early days.

I have created a grid and I am wanting to add a couple of buttons to the right of the actual data however I am struggling...I dont want to use standard buttons I want to use images and have an onclick event on each of them.

My binding class looks like this


Within my win form I have this


If I run the above code it a runs fine....As you can see I have tried adding buttons....
What do I need to do to add the columns.....Ideally when I pressed either of them they would return the selected item ID i.e ItemID


Sorry if this is all asic stuff however still getting my head around win forms

Thank you for your help

How to remove inner grid header?

Hello,

I have an unbound grid with 30 columns and not more than few hundred rows. When the application is in full screen mode (grid takes almost whole screen), the grid is reacting quite slow. When using keyboard to navigate it takes up to 2 seconds to move to next cell even on a relatively fast PC (Intel Core 2 Duo, 1,86 Ghz, 2 GB RAM). It  happens only when navigating left/right, up/down works fine. I noticed that when going into edit mode then all visible rows are refreshed, then when leaving edit mode visible rows are refreshed, and finally when the focus moves to another column all visible cells are refreshed. There is quite a lot of cells to refresh and that seems to be causing the slowdowns. Is there any way to make the grid respond faster to keyboard actions (refresh only the affected cells/columns/rows) ?
I'm using Telerik Controls for WinForms (.net 2.0), tried it on 2008 Q3 SP2 and the newest demo 2009.2 729 (Jul 29, 2009)

Thanks in advance

I have a private instance of a collection of business objects on a form.  On form load, I fill the collection with data and bind it to a treeview.  In reaction to user input elsewhere on the form, I add and remove items from the collection.  At that point I need to refresh the binding of the TreeView.  I tried resetting the DataSource property and I've tried the Refresh and Update methods, but nothing I do makes the TreeView display the new data.

How do I do this?

I seem to have a small problem with the CellDoubleClick event with the GridView.  It seems that when I doubleclick anywhere in the header for each of the rows it processes the event.   How can a prevent this from happening?  Can the header for the GridView be disabled so that when a user doubleclicks any header it won't fire the event? 

Thanks
