If you have a look at the attached, what we are trying to achieve is the date across the bottom, then bars for each of the modules, so on the 10/12/2009, there would be three bars one for balancing, hospitality and membership.
Hope somebody can help

[Solved] Can a ToolWindow be always on top?

I would like a ToolWindow to always stay on top when it is floating. I don't see a property for AlwaysOnTop or TopMost on the ToolWindow class, so does anybody out there have some sneaky code that allows you to do this?

[Solved] Cancel a filter conditionally

I have a situation like this:
I need a filter for a column say ProdNumber==null, so it shows all products w/o a product number. In the grid i am enabling users to enter a product number and save. But since the filter is on as soon as the user save the record, the record disappears from the view based the filter. But the users would like to continue to see that record until they manually trigger the filter again. How can i do this?
How can i cancel the automatic filtering and provide a button or something to trigger the filtering?
I tried to use this , but did not get fired before the automatic filtering:

void radGV_FilterChanging(object sender, Telerik.WinControls.UI.GridViewCollectionChangingEventArgs e)

{

e.Cancel =

true;

}

Thanks
anu

force user text ToUpper() in TextBox Columnr?

I'm looking for an right approach to both limit and alter the text being typed in a textbox column?

For the given cell column, I'd need to limit the user input to a range of characters (A-E,0-9), but also auto-uppercase the values as they are being typed in? I've also tried to split the validation and uppercase portions in two separate events, but the real-time uppercase always seems to get me stuck.

I've looked at ValueChanging, as its raised for each keystroke, but changing the cell value within this event causes a stackoverflow, and changing the e.NewValue does not have any effect.

I've also tried CellFormatting - but that only formats the text after the edit is completed.

Thoughts?

RadGridView won't FullRowSelect

I've been going around and around with this. I have a RadGridView in which I want the user to be able to click rows, but not select individual cells. I basically want no cell highlighting.

I have the selection mode set to FullRowSelect - and I've tried setting this both through the property inspector and via code - and yet a click on any given cell will select that cell and not the row.

I've gone so far as to add an event-handler for the SelectionChanged event and trying to clear the selection there with RadGridView.ClearSelection() but the cell remains selected.

What am I missing here?

[Solved] Total number of rows in a group

Hi,

I'm sure this is a quick issue but i'm struggling to find a solution on my own. Basically I used to have it where I would create a group and have the total number of rows within that group inside the group head. I used to use the following code

private void radGridView1_GroupSummaryEvaluate(object sender, GroupSummaryEvaluationEventArgs e)

{

int contactsCount = e.Group.ItemCount;

e.SummaryItem.Name = contactsCount.ToString();

}

But now that i've returned to my project after a break and updated to the latest controls, this no longer seems to function. Have I made an error somewhere or has the procedure completely changed with the latest version?

Regards,

Guy

[Solved] Cell editing by pressing ,

Hi

I have a decimal Column in RadGridView with BeginEditMode = BeginEditOnKeystrokeOrF2 and using Danish culture.

When user presses ',' on the selected cell, cell goes to edit mode but ',' is not inserted in the cell. But if user now again presses comma, then it is inserted into the cell.

So if user wants to enter the value ,5 he has to press comma twice. Ofcourse he has no problom in entering 0,5

Note, this is when user enters to edit mode by pressing , not by pressing F2.

What should I do? Any help would be appreciated.

Thanks

Regards
