why does the spreadsheet lose focus when you make an input? 

How can I guarantee that I only trigger a LostFocus event when I leave the control?

Hi,

I am using the 2011.2.11.712 build of the WinForms controls.  When I set the RadMaskedEditBox MaskType to "Email", it works correctly and shows the icon when the value is invalid.

But, how do I detect in code that the validation failed? 

I have a form where the user enters an email address and I want to detect that the user entered an invalid value and not allow the save but rather show an error message.

Thanks

First the problem I am trying to solve:  gridview's SearchRow by default uses "Contains" for GridViewTextBoxColumns.  I need to change this to "Starts With"

I searched the KB and found this article: https://docs.telerik.com/devtools/winforms/knowledge-base/starts-with-search-in-radgridview and its ALMOST perfect!

It was VERY easy to implement and it works...sort of :(

 

Ok so it works "sort of" and you get only the rows that "Start With" that match whatever you typed into the Search Row (I have AutomaticallySelectFirstResult = True.)

Now click the "next" or "previous" button on the search row...nothing happens or rather it happens in the blink of an eye:  The first row that matches is selected from the search.  Click Next and it deselects that first row...and then reselects it.  If you click the "Previous" button it will in fact jump to the very last match.  Click it again and it clears the selection, and re-selects the same row.  It does not crawl through the collection of found results :(

 

The expected behavior would be the grid selects the next row when you click the "Next" button.  Click this again and again the grid should select the next row that matches and so on.  Same for the "Previous" button only in reverse.  Finding a solution to this is my immediate problem.

 

More on the "Sort of" working new custom search - what the article describes is creating a class called "CustomSearchRow" and there's an overridden method contained within called "MatchesSearchCriteria" and this returns a Boolean that if the cell "StartsWith" returns True and False otherwise...here's why I say it "Sort of" works:  If you have a cell with "All Good People" and you search for "P" it WILL find this...that cell does NOT start with "P", it starts with "A" and should NOT be found.  If anyone knows a way around this your help would terrific!

Want to get rid of the Drag a column here to group above the column header text.  Do not need this feature.  Can not locate the setting for this.

We need the ability to use the underline field for each column instead of the column display name as the field in the export file.  Our column display names are built dynamically and it is possible that we can have two columns display names being the same. Their underline properties will be the different, therefore, we want to use that in the export.  

 

Any help would be great.

 

Thanks

I have a CardView running in Bound Mode.   I am trying to allow the user to select a choice via a double click.   The only double click event I see being raised is the overall CardView.  This just returns an X and Y click point.  How do I get from this to the databound item that was selected?
