I can no longer drag a column header to the group by box at the top.  Not sure when this stopped working.  When I click on the column header it is highlighted, but I can not drag it.   Does it have something to do with the drag and drop of rows I added to my app. I am using your provided service for the row drag and drop.  I believe I have everything enabled.

                dgvFiles.ShowGroupPanel = true;
                this.dgvFiles.AllowSearchRow = true;
                dgvFiles.Columns[1].AllowGroup = false;  // prevent grouping of Path Column
                dgvFiles.Columns[2].AllowGroup = true;//filename
                dgvFiles.Columns[3].AllowGroup = true;// length
                dgvFiles.Columns[4].AllowGroup = true; // catagory

i'm trying to compare 2 listview items to check for duplicates

one listview is in a form and the other one is in a different open form

i get this error :

System.InvalidOperationException: 'Collection was modified; enumeration operation may not execute.'

how to solve this error please 

When I type text in the search box, several non-matching rows are selected.  The number that shows to the right in the search box, but the actual number of rows selected is wrong.  I am using the following event code to get the selected rows. I am writing the number of rows selected to the console.  I have attached a screenshot of the issues.

 private void TableSearchRow_SearchProgressChanged(object sender, SearchProgressChangedEventArgs e)
        {
            GridViewSearchRowInfo searchRow = sender as GridViewSearchRowInfo;

            if (e.SearchFinished && searchRow.CurrentSearchResultsCount > 0)
            {
                foreach (GridSearchResultCellInfo cellInfo in e.Cells)
                {
                    cellInfo.RowInfo.IsSelected = true;
                }
            }
            Console.WriteLine(dgvFiles.SelectedRows.Count().ToString());
        }

Hi Guys

I need to pass a list of addresss which i want to display on a bing map similar to 

currently I use the following for a single address string

 Dim request As Telerik.WinControls.UI.Map.Bing.SearchRequest = New SearchRequest()

        request.Query = addresses(0)
        request.SearchOptions.Count = 10
        request.SearchOptions.QueryParse = True

what  approach i should use for multiple address??

Ideally I would like to use a data table which lists an  address in each row of the datatable along with some additional data for displaying on a callout (no geo coordinates) and then add a pin for each address onto the map

 Many Thanks

Andre

Hello,

I am trying to figure out how to make the Suggested Actions not scroll off of the screen in Windows forms.

Can you help show how I can get these to be posted vertical?

Thanks -Tim

Hi, I need to retrieve the text contents of AutoCompleteBox in Javascript (client side).

I tried this but it just alerts me nothing (blank result):

<script>

function CheckOE() {
            alert(document.getElementById('RadAutoCompleteBox1').value);
        }

</script>

<telerik:RadAutoCompleteBox RenderMode="Lightweight" runat="server" ID="RadAutoCompleteBox1" ClientID="RadAutoCompleteBox1" 
            autopostback="true"
            DataSourceID="blah" DataTextField="blah" DataValueField="blah" InputType="blah" Width="100%"
            AllowCustomEntry = "false"
            DropDownWidth="150px"
            onfocusout="CheckOE()"
            >

Any idea?

Thanks!

I want to distinguish between: 

A) Tab close.

B) Tab being dragged out into a new parent window  

Both of the above call: TabRemoving, TabRemoved

What is the proper event or technique to distinguish between A and B?

I am using your drag and drop service between grids.  Code is working fine for 10 rows.  Lager multirow selections error out.  I have experimented and have determined that if the rows are not showing in the grid I get this error.  For example, if my grid visually shows 10 rows and I select all of those rows and drag them to another grid all works fine.

If I select the first row and scroll down to select the 11th row while holding down the shift key, all eleven rows are selected.  However dragging then to the other grid I get an error in the svc_PreviewDragDrop method on the line:      var dragGrid = rowElement.ElementTree.Control as RadGridView;
