how fix?

I'm using the Fluent dark theme.  Works fine with crystal.

Hello,

I have telerik version 2014.1.331.40. I want to make a ComboBox filter in FilterRow mode in the RadGridView control. I need it to work exactly like the Textbox does, only with the ComboBox instead. I tried editing the control template of StringFilterEditor, but then I lose all functionality and when I try to bind the DisplayMemberPath, it doesn't work or when it does through code behind, it is very slow while I type what I want to Filter (I need to do Filter as you type which I did with the Textbox) (I use a large amount of Data).

Please help,

Bar.

I use a RadGridView for displaying data from a database. I'm on .NET Core 3.0 and use Telerik UI for WPF 2019_3_1023 NuGet NoXaml Version oft the controls. 

I have encountered a strange behaviour when i do grouping for some columns. The group header row is displayed correctly with the expander button on the left side, followed by the grouping information. The strange thing is, that clicking on the expander icon (arrow down) doesn't expand the grouped rows. Only clicking the text representing the items the grid is grouped after expands the row to show the grouped rows. I have some implicit styling applied (mainly colors, font and row height of the grid) and use the material design. Even after removing the implicit stylings, the grid behaves strange. Can't geht the expander button to work, which is annoying for customers, as they expect that the icon responds to clicking (as seen in the Telerik Demo app for example). Is it possible that the styling could affect the expander button behaviour?

 

Thanks,

Martin

Hello  we are facing problem while exporting direct from RadGridView to Excel. After exporting data, three problems are there in excel sheet.

1. Phone numbers are getting chopped off [Like "8.70772E+11" instead of "870772001799"]

[Instead of In DataTable PHONENUMBER is in String type]

2. Phone numbers are displaying as Right Align [Instead data type is String]     

[Images given "Image .XLS file after exported .png"]

3. Group name is not showing in Excel sheet  [Only first group is not showing]

Please advice.

Screenshot are given & the used code given bellow.  

private void Button_export_Click(object sender, System.Windows.RoutedEventArgs e)
        {
 
            string extension = "xls";
            string selectedItem = "Excel";
 
            ExportFormat format = ExportFormat.Html;

            SaveFileDialog dialog = new SaveFileDialog();
            dialog.DefaultExt = extension;
            dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, selectedItem);
            dialog.FilterIndex = 1;
 
            if (dialog.ShowDialog() == true)
            {
                using (Stream stream = dialog.OpenFile())
                {
                    GridViewExportOptions options = new GridViewExportOptions();
                    options.Format = format;
                    options.ShowColumnHeaders = true;
                    
                    options.Encoding = Encoding.UTF8;
                    radGridViewSearch.Export(stream, options);
                }
            }

            MessageBox.Show("Successfully Exported");
 
        }

Hi,

     I'm using RadGridView to show List of objects. Suppose one row contains a common cell(GridViewDataColumn) and a combobox cell（GridViewComboBoxColumn）. After I edited the  common cell everything goes well, but while the combobox cell edited the RowEditedEnded event will be raised. In fact I stll need to edit other cells. Any suggestions to prevent this?

Thank you!

Hello,

 

I merged themes in Application.Xaml like this

And this is working correctly, but as soon as I merge this file (which I need for my project) every ordinary button in my project merges this Expression dark theme (which I do not want).

 

 I am aware that merging System.Windows with this theme changes button style but in this case it is not merged, and it still looks different.

So, two questions:

1.) How do I merge Telerik.Windows.Controls.Navigation with this Theme without merging ordinary buttons also with this theme?

2.) Is there any way I can merge this theme to System.Windows this but only to tooltips and scrollbars?

 

Thank you

 

Hello All.

I've a GridView with a checkbox column 



Now it seems the binding is updated only on lost focus (for example, when clicking on another cell/row) and not according to the UpdateSourceTrigger= PropertyChanged.

This is a problem for me, since I've a menu bar which has commands (like delete) which work on the selected rows, and when the menu item is clicked, the Checkbox binding isn't yet updated. Basically you have to select the checkbox, click on the grid outside the checkbox, and only then click on the menu item.Is there indeed a problem here, or am I doing something wrong? Should I simply use GridViewDataColumn with checkbox instead of GridViewCheckBoxColumn?

Yours,
Roee

Given the following (simplified) class...

    class SearchResultsViewModel
    {
        public IList Results { get; }
        public SearchCriteria Criteria { get; }
    }

And the following (also simplified) WPF DataTemplate's...

    <DataTemplate DataType="{x:Type viewModels:SearchCriteria}">
        <StackPanel>
            <!-- Various controls used to display/edit  the SearchCriteria class properties-->
        </StackPanel>
    </DataTemplate>

    <DataTemplate DataType="{x:Type viewModels:SearchResultsViewModel}">
        <telerik:RadDocking>
            <telerik:RadDocking.DocumentHost>
                <telerik:RadSplitContainer>
                    <telerik:RadPaneGroup>
                        <telerik:RadDocumentPane Visibility="Collapsed"
                                                 CanUserClose="False">
                            <telerik:RadBusyIndicator BusyContent="{Binding Path=BusyContent}"
                                                      IsBusy="{Binding Path=IsBusy, Mode=OneWay}">
                                <telerik:RadGridView ItemsSource="{Binding Path=Results}" />
                            </telerik:RadBusyIndicator>
                        </telerik:RadDocumentPane>
                    </telerik:RadPaneGroup>
                </telerik:RadSplitContainer>
            </telerik:RadDocking.DocumentHost>
            <telerik:RadSplitContainer InitialPosition="DockedLeft">
                <telerik:RadPaneGroup IsContentPreserved="True">
                    <telerik:RadPane CanUserClose="False"
                                     CanFloat="False"
                                     DataContext="{Binding Path=Criteria}"
                                     Header="Search Criteria"
                                     IsPinned="False">
                        <ContentPresenter Content="{Binding}" />
                    </telerik:RadPane>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
        </telerik:RadDocking>
    </DataTemplate>

When I display the SearchResultsViewModel (using a ContentPresenter), I see - as expected - a list of the results along with a tab on the left of the page with the header "Search Criteria"; however when I then click on the tab to open the associated panel and view the properties of the "SearchCriteria" class I see a repeat of the whole "SearchResultsViewModel" DataTemplate instead of just the properties of the "SearchCriteria" using its own DataTemplate. This then repeats recursively so each time I click on the tab it opens yet another copy.

I have also tried setting "Content={Binding Path=Criteria}" on the "ContentPresenter" instead of setting the "DataContext={Binding Path=Criteria}" on the "RadPane" but this makes no difference.

I use the DataTemplate for the "SearchCriteria" elsewhere within the application and it is called upon based upon the DataType being shown rather than any specific reference to the specific template so I do not want to have to give the template an "x:Key" and then reference it specifically here either but then I do not expect to have to do this as it works elsewhere.

What am I doinng wrong to make the ContentPresenter within the second DataTemplate show the "SearchCriteriaViewModel" DataTemplate instead of the "SearchCriteria" DataTemplate?

     Hello,

NOTE:
