Hi,

I'm new to RadControls so forgive me if it is a basic misunderstanding, The problem I'm having is understanding to how to layout my Windows Forms. I am dynamically adding RadControls Checkboxes to the RadPanel. However, after adding them, I see all of them next to each other and behind one another. I would like each of them to be in a new line. Please advice on how to achieve this.

Regards,
JB

I am using GridView for Winforms and the data is bound using a dataset. One of the columns in the dataset's table is an integer column. I have enabled Filter's for this column in GridView and this shows up as a funnel. When I right click on the funnel, there is a context menu with all the filtering options (No filter,Equals,Not Equals etc). When I click on the "Between" menu item in this context menu, the application crashes with the System.Argument exception {"Not enough values."}. The complete stack trace below.
How can we fix this behaviour, Is there any way to programatically disable some of the menu items.

The What's New for Q3 2008 says that it's now possible to layout the gridview in an HTMLView.  I don't see any documentation on how to do this.  Has anyone figured this out yet? Are there samples somewhere?

Hi, I'm using GridViewAutoSizeColumnsMode.Fill which looks great however I want a couple of columns to have a fixed width that stays the same, and the rest to be sized appropriately by the grid.

I've tried fixing the two columns by setting their width manually with AllowResize false as well as the [Max]MinWidth... but the 
GridViewAutoSizeColumnsMode.Fill  overrides this and resizes the fixed columns.
 
This is most noticable when you drag one of the non-fixed columns to the group bar - I want fixed width columns to stay the same size and the remaining floating width columns to expand dynamically to fill.

If it's not possible for the Fill to account for fixed width columns (ideal solution/feature) then manually i could calculate the sizes myself if there is some way of knowing the width available in my grid -- obviously it changes depending on whether there is a vertical scroll bar present.

Hi,
I have a RadGridView that is populated by dynamic SQL.  When I click a checkbox field and click 'Save' the checkbox reverts back to off.  Any ideas ?

Thanks,
Derek.

Hi,

I've seen that since the Q1 2008 Release, RadGridView supports multi-lined text in rows. On my side it displays the line break correctly but the row does not scale to fit the text. With that the text on the second row in my Cell is cut off by the next row.

Another problem:
I bind the GridView by giving it a DataTable as DataSource. There is one column in my DataTable that gets shown in the grid but not its vlaues, wich are there in the DataTable. All other columns from the DataTable are displayed properly. Is it somehow not engough to do grid.DataSource = DataTable? Wenn I manualy change a value of this column inside the GridView while debugging it works fine.

Hi, is it possible to use the conditional format object to format rows based on a checkbox value?  if the value is true I want to apply a format, like the excerpt from the documentation above.  When I've tired with equal/greater than 0/1 it just raises an exception.  If it's not possible in this manner, can you consider adding a IsTrue/IsFalse ConditionType.

I also tried to achieve what I wanted by:  
But this didn't work... initially i through it did but once I added more rows and started scrolling up and down then everything just started getting hilighted in red!

ps the help page ms-help://telerik.winforms.8.0/telerik.winforms/topic24361.html has &amp etc errors in the c# example.

Hello,

I'm trying to change the default labels on the XAxis from 1,2,3,4,5 etc and use the value from one of the fields in my bound table? I've seen examples that should do the trick, but I've tried and I can't get those labels to change, even when attempting to hard code values into them.

Please advise.

Thanks,

Hi,

I'm creating an WebEditor with the Ribbonbar in Vb.net.

My problem is, that always if I press Alt, the Ribbonbar

gots the focus. That's a big problem, because

the user can't write chars like "{" or "}", wich are

very important for writing Website ( for Example in PHP ).

Can I deactivate it, or is there any workaround?

Is there any way to turn off the sound on the grid which occurs when a user is adding/changing a column and tabbing out of it.  It also beeps when the new row is added.  This is highly irritating!!!  How do I turn it off?  Thanks!
