Hi DevExpress Team,
how to do concatenation in column header of WPF GridControl using xaml.
<dxg:GridColumn Name="CommandMapped" dxgext:BandedViewBehavior.Row="0" dxgext:BandedViewBehavior.Column="0" dxgext:BandedViewBehavior.ColumnSpan="4" dxgext:BandedViewBehavior.IsBand="True"
Header="{Binding Path=View.FocusedRow.Name, StringFormat='{}{0:CommandsMappedTo}'}">
Thanks,
Sasidhar Muvvala
Hello Sasidhar,
For string concatenation use MultiValueConverter. I have created a simple example of how to solve this issue:
C#public class StringConcatenator : IMultiValueConverter {
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) {
return String.Concat(values);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture) {
return new string[] {};
}
}
XAML<sys:String x:Key="mappedToString">CommandsMappedTo: </sys:String>
<dxs:StringConcatenator x:Key="stringConcatenator"/>
<dxg:GridColumn FieldName="Name">
<dxg:GridColumn.Header>
<MultiBinding Converter="{StaticResource stringConcatenator}">
<Binding Source="{StaticResource mappedToString}"/>
<Binding Path="View.FocusedRow.Name" RelativeSource="{RelativeSource Self}"/>
</MultiBinding>
</dxg:GridColumn.Header>
</dxg:GridColumn>
A full project is located in the attached archive.
Hi,
You can use the following binding:
XAML<dxg:GridColumn FieldName="Name" Header="{Binding FieldName, Converter={local:Converter}, RelativeSource={RelativeSource Self}}"/>
I've attached a sample demonstrating this approach.
Hope this helps.
Hi Sasidhar,
Thanks for the clarification. I understand what you mean. You are right, you can use the StringFormat property in the binding to add a static string to the resulting value. I've found a link that describes the use of the StringFormat: Trying out Binding.StringFormat. Once you look over it, please let me know if you need further assistance.
i am using devexpress grid control… the gridroles is mastergrid…it is not throwing any error…
when i used the first approach it is not showing any text
when i tried the second approach string concatenation is not working but the dynamic value which is dynamically binded is displaying correctly but its not getting concatenated with the static string
Hello,
You can find the sample project in the last answer on this page. Please take a moment to review it and let us know if you need further clarification.

Hi,
As I can see in your code snippet, you created a Band column, and this column spans several columns. I'm afraid that the issue is not clear to me. Would you please explain it in greater detail, or provide me with a sample project? I am looking forward to your reply.
i have one static value and one dynamic value, i want to bind these two values together in the Header of GridColumn
