Hi, everyone. For example, I have such chunk of code:

Why style for telerik:RadTabItem (lines 14-18) is not working at all ? Thanks in advance !

Hello,

I'm using IsolatedStorageProvider to save/load RadGridView settings in my application and I also wanted to provide the ability to serialize/deserialize settings when the application gets updated to a newer version of Telerik controls. If I were to use PersistenceManager, this would be possible via PersistenceManager.AllowCrossVersion property, but I cannot find anything similar when using IsolatedStorageProvider.

How can assembly upgrades be handled with IsolatedStorageProvider?

Hi,

Please have a look at the attachments.

When I launch the view, the MultiColumnComboBox is displayed as in issue 1.  When I increase the width of the view, I is displayed as in issue 2.

I do not understand why I have issue 1 as there is clearly enough space to display the content of the selectionbox at startup.

Any ideas ?

Regards,
Hans

I want to change the Header row mouse over/selection background color and I am not getting any properties for that in wpf rad grid view.

please help.

Hi,

I'm using the RadMaskedNumericInput with Mask="#6.2".  SelectAll() is called when the control gets the focus.  This works fine as long as the value of the binded property is not zero.  In this case, only the decimals and decimal point get selected, but not the zero digit before the decimal point (see attachment), which is very annoying behavior for the end user.

Regards,
Hans

Hi,

Could you please help me to figure out how to define columns and properties for all-level nested tables in hierarchical gridview?

I'm referring to pages:

https://docs.telerik.com/devtools/wpf/controls/radgridview/hierarchical-gridview/basic-hierarchies

https://docs.telerik.com/devtools/wpf/controls/radgridview/hierarchical-gridview/how-to/access-child-gridview

But columns and properties AutoGenerateColumns and ShowGroupPanel are applied only for first child table and second-level table and deeper is not affected by that property.

I have a bit of a programming challenge…

We have a form that has a RadGrid whose itemsource is bound to collection.  That collection includes a Boolean field named ‘Selected’.
The form also has a ‘Select all’ button.

The user filters the grid based on customer, so it is displaying only 10 of the 50 items in the collection.

When they click the ‘Select all’ button, they want the items Selected property to be true for only the 10 records that are displayed in the grid.

If I can get a collection of just the rows displayed in the grid I could roll through both collections to locate matches.   I haven’t figured out a way to get the ‘filtered’ collection, and wonder if there is a more efficient way to accomplish the task.

Any ideas would be greatly appreciated.

Thanks in advance,
Lou

              if (ribbon.SelectedItem is RadRibbonTab)
                {
                    //keepBackstageOpen = false;
                    //MasterRadRibbonView.IsBackstageOpen = false;
                    System.Diagnostics.Debug.WriteLine("RadRibbonTab");
                }
                else if (ribbon.SelectedItem is RadRibbonBackstage)
                {
                    //keepBackstageOpen = true;
                    //MasterRadRibbonView.IsBackstageOpen = true;
                    System.Diagnostics.Debug.WriteLine("RadRibbonBackstage");
                }

        }

If I click on the backstage, this always triggers as a tab (the last one selected), and not as the backstage...which is causing me many problems.

Any advice ?

Good morning, i had a issue when a try to move the RadPane that contains the RadGridView only when i use the theme VisualStudio2013. I try everything, with  any other theme work just fine. Pop into Output window in Visual Studio the following binding error for each column i have int the RadGridView, and it slows the application in a way that is very painful :

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor AncestorType='Telerik.Windows.Controls.GridView.DataCellsPresenter', AncestorLevel='1''. . BindingExpression:Path=Foreground; DataItem=null; target element is 'ContentControl' (Name='PART_ContentPresenter'); target property is 'Foreground' (type 'Brush')

I try taking of styles of header cells and such, but does not work. The others themes works with custom styles and without it.
