Hello
I would create my own RadComboBox (for adding features) and add a button at right (see capture)
I create a control inherit of RadComboBox :

public class MyComboBox : Telerik.Windows.Controls.RadComboBox

{

}

And associate style :

<Style x:Key="MyComboBoxStyle" TargetType="Controls:MyComboBox">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="Controls:MyComboBox" >

<Grid x:Name="LayoutRoot">

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"/>

<ColumnDefinition Width="Auto"/>

</Grid.ColumnDefinitions>

<telerik:RadComboBox x:Name="PART_RadComboBox" Grid.Column="0"

ItemsSource="{TemplateBinding ItemsSource}"

SelectedItem="{TemplateBinding SelectedItem}"

SelectedValue="{TemplateBinding SelectedValue}"

DisplayMemberPath="{TemplateBinding DisplayMemberPath}"

SelectedValuePath="{TemplateBinding SelectedValuePath}">

</telerik:RadComboBox>

<telerik:RadButton x:Name="PART_RadButton" Grid.Column="1" Content="+"/>

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

But MyComboBoxStyle is never use, I think RadComboBox always override my style because if I inherit System.Windows.ComboBox it's work.
Can you help me ? Or I must create UserControl and rewrite all DependencyProperty of RadComboBox ?
Thanks in advance

PS : I use Telerik 2014 Q2.

Custom template with editable field

Hi,

I have a RadGridView with a custom template (as seen in the attachment).
How do I make the fields be editable?
Specifically, I want the description field to be editable when a user click on it. Just as a regular GridView with GridViewDataColumn.

Regards,
Daniel

Grouping issue in WPF radgridview, some groups will automatically expand

Hi telerik support,

- In radgridview, when I apply grouping, some groups will automatically expand even if i scroll data (using EnableRowVirtualization = true).
I just want to expand the group when i click header group.
- Other hand, when grouping I select a record and update this record in code, the issues is UI not updated so i must use method ReBind().
(with same step, if i don't group data, everything is okay)
- Please tell me some infomation about grouping in radgridview.

Thanks a lot.

Dynamic binding to a ComboBox Columm

I have a RadGridView that displays a list of dates.

Each date has a corresponding column called "Status" which is a ComboBox column.

My problem is that the ComboBox column list options vary depending upon the type of Date.

Is it possible to dynamically vary the itemsource per row based upon the date type?

I found this example which is close to what I need but am not sure if this can be implemented in the Telerik GridView.

Example: http://sekagra.com/wp/2013/04/dynamic-itemssource-for-combobox-in-a-datagrid/

Any assistance is Much Appreciated!

Create a text search for RadGridView (not filter)

Hi,

I have a requirement from our client to have a simple text search option available to them in the grid. I know that the grid filtering options cover most of this ground, but it really needs to be a search where they type and matches are made in the grid.

We were able to do this when we used Infragistics by customizing the group panel and making it into our search area (we have no requirement to use grouping). See attached screenshot.

Any help you could give me would be greatly appreciated!

No ErrorTemplate ?

It appears that RadTimePicker don't show anything (like red border and IDataErrorInfo.Error), is it normal ?

I wrote :
public partial class MyItem: IDataErrorInfo
{
public TimeSpan Duree { get; set; }

public string this[string columnName]
{
get
{
string result = null;
switch (columnName)
{
case "Duree":
if (Duree.Ticks <= 0)
result = "Un(e) Durée est requis(e)";
break;

default:
result = null;
break;
}
return result;
}
}

public string Error { get; private set; }
}

<telerik:RadTimePicker SelectedTime="{Binding MyItemInstanced.Duree, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}"
