I've noticed that Grid.Selection.SelectedRegions returns the dataset row number values whenever a paging-enabled virtual grid page changes. i.e the selection may be on a different page than the one on view.
I'm having problems generating elegant code for moving the regions from page to page so they select from the page of data that's on view, including cases where a full page of data has less rows than the original selection.
The help file isn't very explanatory,
radVirtualGrid1.VirtualGridElement.Selection.BeginSelection(3, 1, radVirtualGrid1.MasterViewInfo, true); radVirtualGrid1.VirtualGridElement.Selection.ExtendCurrentRegion(6, 3);
If I've several individual rows selected then how do I manipulate the grid.selection.selectedregions so that I can assign the whole set of regions? following is the code Im trying but Im having a real struggle understanding what Im doing.
01.
var selectionRegions = Grid.Selection.SelectedRegions;
02.
var offset = Math.Abs(e.NewIndex - Grid.PageIndex);
03.
var multiplier = e.NewIndex > Grid.PageIndex
04.
? PageSize * offset
05.
: -PageSize * offset;
06.
var newRegions = new List<
SelectionRegion
>();
07.
foreach (var region in selectionRegions)
08.
{
09.
var newRegion = new SelectionRegion(region.Top * multiplier, region.Left,
10.
region.Bottom * multiplier, region.Right, region.ViewInfo);
11.
newRegions.Add(newRegion);
12.
}
13.
Grid.Selection.SelectedRegions. <- and here is where everything goes horribly wrong :)
Hi all,
I've implemented a radgridview in my project, and I need one column to search, in this case, a barcode but I have two ways for search it. The barcode and a small code which are related between. So I've implemented a multicolumncombobox and a composite filter to do this. It works, but I have a problem in some cases. When the combobox has a lot of data, the filter which has the property autocompletemode as suggestappend, it is working too slow. For example, I press one key it takes too long time to appear in the column, it appears to be freeze.
Do you know how to improve this? Or there is another control to make this purpose?
Thanks in advance.

Hi
I have an issue with the validation of email addresses using when the mask type is set to EMail, it is not allowing the following style of email address "t.harris@working.group" (note this is not the exact email address of obvious reasons), it does work when i append .co.uk or .com on the end.
What are the validation criteria for this EMail validation ?
Do I have to use an edit mask instead ? If so can you give an example which will allow above email address as well as those in more "normal" formats ?
Regards
Toby
Hello All,
Is it possible to validate the text enter as the user types (ie validate on TextChanged) as opposed to validating as focus is changed?
Thanks!!
if you completely delete the contents in the editor and press the <Enter> key, then int.MinValue is returned.
Why? In this case, you must return either null or 0 or do nothing.
Hi,
I'm able to get the samples to work but I'm having trouble adding to my project. It seems that TreeViewElement_CreateNodeElement isn't firing.
Can anyone see what I might be missing? The code below just needs a radtreeview named tvProjectPath.
Thanks in advance!!

I was prompted to download a new version, did so.
Created a new project using option one from the dropdown. Could not add any controls to the default form. I thought it was strange that it said [Download] but tried any ways.
Next I created a new project with option 2, worked fine.
So my question is, how do I use option one marked as [Download] even though I already downloaded it and saw zero errors?
Thanks for your time with this matter.

Hello.
In my program I need to create a UserControl that contains Telerik Controls and place them on forms (using RadForm). Everything looks fine until you change the DPI settings in the system. Image with the result of the work of the form in the attached files. At the top of the screen, it's just on the form, at the bottom I'm using UserControl. Tell me how to fix it. For RadForm and UserControl, I set AutoScaleMode.DPI and also I need to use the font Segoe UI 9.75
I use Telerik 2018.2 with .Net 3.5 Below I gave examples of my code (Forms and controls). I very much rely on your help and advice.
