Hello,

I have an MDI App using a DockingManager. The DockingManager is in the main Form. Rather than using AutoDetectChildForms and create DocumentPanes automatically by MDIChild Forms additions to the main Form, I prefer using custom DocumentPanes that I add programmatically to the DockingManager (because the AutoDetectChildForms feature clears the main Form's MDIChildren collection, and its a pity).

It works well... But !... any RadGridView designed on a custom DocumentPane doesn't fill with datas and doesn't display anything. (Even with this simple sample, 
List<string> myList = new List<string>();
myList.Add("One");
myList.Add("Two");
myList.Add("Three");
radGridView1.DataSource = myList;
)

Of course, I checked that the program does execute the lines above, the DataSource is well defined but the grid doesn't display anything. If I put the grid on a simple form, it works, of course.

What's going wrong with that ?!

When we are adding a colum in gridview its visible like a  simple column in grid.
Can we show as textbox clearly in gridview as we show in ASP Grid?
If so how?
I have tried cellfomatting and rowformatting, but its not upto the mark.
Please suggest me how can we achive this.

Telerik team,

I was hoping someone could assist me with a problem I am having?
I currently have a radlistbox that I am using as a log window, which is working and looking very well until now. It seems that all the radlistbox items inside all have to be the same height. for example if I log a simple "hello" looks great but if i add another item into the listbox that says     "hello" [newline]
                                                                    "how" [newline]
                                                                    "are" [newline]
                                                                     "you"
the second item is now the same size as the first one.
This comes as a big problem when trying to log exception data and stacktraces.

Any help would be appreciated, thank you.

I am experiencing an issue with RadTreeView giving me an error in Visual Studio that is to the effect of the following:

System.ArgumentException "Control does not support transparent background colors."

I have a split container control, which is a slider control that allows me to resize the panel that contains the RadTreeView. I notice whenever I resize the panel so that the text on a node is not visible, this exception will appear. Here is the stack trace from the error:

I am unsure if there is a value in text that I have not yet but I'm sure it isn't. I notice the tree automatically gives me a vertical scroll bar and I can scroll up and down without any issues. Maybe this issue can be resolved if I can implement a horizontal scroll bar in my application whenever the panel is resized?

Your help is greatly appreciated, thank you

Dear All,

Can any one tell me how to have the theme in the Resource and use it?

Thanks a lot in advance.

Hi

I am new to the radGridView windows control, may I ask a couple of questions?

1. I have a data source of 20 columns/properties, but i only require to display 5 of them in the grid. I have manually added the columns that I require to the grid. When binding to the data source all of the remaining columns are loaded as well, how can I stop this auto generation of columns?

2. In the Property Builder design view of the grid I, have created a view and added the required columns. Can I add another view and add another set of columns (all from the same data source)?

Thanks

P

Dear All,

Actually, I have an application, which will configure the grid settings.

After all the configuration, it has to show the preview of the grid.

For this I am creating a sample data set in the application and binding the same to the grid.

It also has a Image column and for this image has to be taken from the application and a tool tip has to be from the other field.

Can any one tell me to achieve this?
 
Thanks a lot in advance.

Hi,

how can I programatically set Height of DocumentPane's tabs, docked in DockingManager?

Also, when I add some DocumentPane with multiline text e.g. "Some\r\ntab\r\nitem" then the tab's height is not as height as necessary.

TIA

Hello,

I am evaluating RadControls for Winforms (specifically RadGridView).

My needs are simple. There is no database at the moment. I need to dynamically add rows or replace any of the existing rows with new contents. There will be no more than 100 rows.

Can I use RadGridView for such simple purposes? I get the impression that the grid control can do very complex things but I am not sure how to do simple things.

Is there sample code available that will illustrate how to use the grid for simple needs such as above?

Thank you in advance,

Hi Telerik,
I did used telerik treeview last year, and I checked the incremental search functionality, which was working fine. But just few days back I developed a prototype for my client to get telerik evaluated by them with Q2 2008 WinControl. And in this when I checked the incremental search functionality I didnt found it working fine ( or as fine as it was earlier).

Right now what happens is that the treeview get the first letter only and selects the first available node. For example if I type "ABC" the search will select the first node starting with "A" and but never considers "B and C". Please do re test the behavior, Probably I am wrong so please tell me.

Regards,
Haroon.
