How to change Cell Column Type depend on binding data

[SweNz]

Hello Telerik,

I need to change column type of cell from GridViewDynamicHyperlinkColumn to GridViewDataColumn from code behind or data trigger which depend on DataMemberBinding="{Binding status}"  that return "Yes" or "No"

eg. 
GridView1.ItemSource 
fileName = "xxx" , status = "Yes" 
fileName = "aaa" , status = "No"
expected result
      Column 0          Column 1
Row 0 :       xxx        :        Yes        
Row 1 :       aaa         :        No           

[row0,col1 (Yes)] should be DynamicHyperlinkColumn to open a file like XAML below
[row1,col1 (No)] should be DataColumn

XAML

<telerik:RadGridView x:Name="GridView1" AutoGenerateColumns="False">
    <telerik:RadGridView.Columns>
    <telerik:GridViewDataColumn DataMemberBinding="{Binding fileName}" Header="Filename" />
    <telerik:GridViewDynamicHyperlinkColumn DataMemberBinding="{Binding status}"
     Header="Upload Status"      NavigateUrlMemberPaths="status"
     NavigateUrlFormatString="{} file:///C:/{0}.xls" TargetName="_blank" />
   </telerik:RadGridView.Columns>
</telerik:RadGridView>

Please give me some advice.

Hi SweNz,

You should use a CellTemplateSelector in this case. Please check the help topic here.
You will have two templates - the first will contain a hyperlink button, the second will have only a textblock.
Depending on the value of the business object the SelectTemplate method will return either the first or the second template.

Hope this helps.

Hi Veselin,

Thank for your fastest response. Now I got my expect result GridView but I can't open my Excel file or any webpage when i click Fail hyperlink.

XAML

<telerik:RadGridView x:Name="GridView1" AutoGenerateColumns="False">
    <telerik:RadGridView.Columns>
    <telerik:GridViewDataColumn DataMemberBinding="{Binding fileName}" Header="Filename" />
    <telerik:GridViewDataColumn DataMemberBinding="{Binding status}"
     Header="Upload Status" CellTemplateSelector="{StaticResource myCellTemplateSelector} />
   </telerik:RadGridView.Columns>
</telerik:RadGridView>

RESOURCES

<UserControl.Resources>
        <my:MyCellTemplateSelector x:Key="myCellTemplateSelector">
            <my:MyCellTemplateSelector.failStatus>
                <DataTemplate>
                    <TextBlock Foreground="Red">
                       <Hyperlink NavigateUri="http://www.google.co.th">
                           Fail <!--file:///C:/Fail.xls -->
                       </Hyperlink>
                    </TextBlock>
                </DataTemplate>
            </my:MyCellTemplateSelector.failStatus>
            <my:MyCellTemplateSelector.otherStatus>
                <DataTemplate>
                    <TextBlock Text="{Binding status}"/>
                </DataTemplate>
            </my:MyCellTemplateSelector.otherStatus>
        </my:MyCellTemplateSelector>
    </UserControl.Resources>

C#

public class MyCellTemplateSelector : DataTemplateSelector
{
   public override System.Windows.DataTemplate SelectTemplate(object item, System.Windows.DependencyObject container)
   {
            if (item is ImpObj)
            {
                ImpObj obj = item as ImpObj;
                if (obj.status == "Fail")
                {
                    return failStatus;
                }
                else
                {
                    return otherStatus;
                }
            }
            return null;
        }
        public DataTemplate failStatus { get; set; }
        public DataTemplate otherStatus { get; set; }
    }

Hello SweNz,

Actually, in WPF you need to do some additional coding to make the hyperlink open a browser window (you can test with a hyperlink outside RadGridView and it will behaves the same).
Please check this post on how to do it.

Hi

I want declare a DataTemplate with a HyperlinkButton, it shows me the message that the HyperlinkButton is not public:

<loclink:CellLinkSelector.linkYes>
    <DataTemplate>
        <telerik:HyperlinkButton />
    </DataTemplate>
</loclink:CellLinkSelector.linkYes>

What i did wrong?

Hello Marcel,

Actually RadControls for WPF does not offer such a control.
