I want to round the corners on a RadComboBox, but I don't want to go through and edit the template for it. Is there way to do that without going through the hassle of doing that? Potentially just using a setter property or something to do it on the xaml side?

thanks.

Using CellStyle

Hello,

I have a RadGridView, it has 7 columns with boolean data. I want to disable each cell with a true value.

I created a style and a converter, I add the style at runtime using the grid DataLoaded event:

<Style x:Key="myCellStyle" TargetType="{x:Type telerik:GridViewCell}">

<Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource Self}, Converter={StaticResource myConverter}}" />

</Style>

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

            GridViewCell cell = (GridViewCell)value;



            if(cell.Value == null)

                return true;

            else

                return (bool)cell.Value;

}

private void grid_DataLoaded(object sender, EventArgs e)

{

foreach (Telerik.Windows.Controls.GridViewColumn col in gridCheck.Columns)

{

col.CellStyle = (Style)this.Resources["myCellStyle"];

}

In the converter I get a GridViewCell object in the value parameter, but the GridViewCell.Value property is always null.

How can I pass the value of the cell to the converter?

Thanks in advance,

Alberto

Validation on Spreadsheet

I have a spreadsheet control I am going to use for data input. Some cells will need data validation which will pop up a message about the error, and put the red circle around it. I have the spreadsheet control on the form and set my Imports statements, I do not have a ribbon bar on the form. We do not want to allow the users to change the form, just input data. When I put in the following line:

Dim context as new NumberDataValidationRuleContext...

I get type not defined. I will need to apply different rule types to different cells, some whole numbers, some decimals, some letters all with ranges. For example 8-12 for hole numbers, .5-3.0 for decimal, A-B for letters.

I looked through the documentation and must have missed something. How do I apply Validation to cells to ensure they are within the ranges?

Add control to pane header

Hello,

I am trying to add some control to the pane header, I saw this documentation about that, it seems that it's not very complicated using the TitleTemplate property.
The difference in my project is that I am creating the RadPane at runtime. Is it possible to programatically add a control to the pane header? Also I would like to add events to that control.

Thanks in advance,

Alberto

Upgrade to 2015.1.225.45 missing references

I just updated to version 2015.1.225.45 and now I get these error messages:

The type reference cannot find a public type named 'PickerTextBox'. Line 2096 Position 74. D:\Source\WPFPartsCatalogUpload\WPFPartsCatalogUpload\Themes\Telerik.Windows.Controls.xaml

The name "RadRangeControl" does not exist in the namespace "clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls". D:\Source\WPFPartsCatalogUpload\WPFPartsCatalogUpload\Themes\Telerik.Windows.Controls.xaml

I don't use either of these controls in my application. The errors are showing up in the dll's XML; Telerik.Windows.Controls.xaml

Any clues on how to resolve this are greatly appreciated!

ColumnChooser for GridView in a TabControl

Hello,

I have a RadTabControl. Inside every tab there is a UserControl with RadGridView. I want to add a RadDropDownButton with Column Chooser for the GridViews. Like this: http://docs.telerik.com/devtools/wpf/controls/radgridview/how-to/show-hide-columns-outside-of-the-radgridview.html I tried placing it in RadGridView.ControlPanelItems and everything works fine, but it takes a whole row for just one control. Can I put it in RadTabControl.AdditionalContent? How should I bind the Columns property right?

Disabled items can be selected with shift-click

I have a RadGridView with SelectionMode="Extended". The bound items have an IsEnabled property, and the rows are enabled or disabled using this property by modifying the style as follows:

    <uxt:UxtWindow.Resources>
        <Style TargetType="{x:Type telerik:GridViewRow}" BasedOn="{StaticResource GridViewRowStyle}">
            <Setter Property="IsEnabled" Value="{Binding Path=IsEnabled}"/>
        </Style>
    </uxt:UxtWindow.Resources>

This is fine in so far as the disabled rows are correctly displayed greyed-out, if I click on a disabled row it is not selected and if I click on a disabled row with Control held down it is also not selected. The problem is that if I click on a row above a disabled row, hold down Shift and then click on a row below the disabled row, all the rows between the two clicked-on rows are selected including the disabled row.

Is this a bug and is there anything I can do about it?

Hello!

Is there a way to set cell B invalid in cell-A-validation?

For example:
cell A - customer-ID
cell B - country

1. User sets the country (B) to Germany
2. User changes the customer-ID (A) <- this customer-ID does not allow Germany
3. Cell B should now be set invalid

kind regards

High contrast theme ?

Hey all.

I was just playing around with the new Office inspired templates (they look great !), and have a query.
When I set the Windows Theme to high contrast, the Telerik application does not follow suit, which is an issue where accessibility is concerned.

I've attached a screenshot to illustrate my point.
