[Solved] ComboBoxEditor - no edit mode

[Jack]

Is there a way to make the comboBoxEditor be editable?  I would have thought it had all the same options as the RadComboBox.

I want to have a drop down with a list of 1-4 but if the user types a 5 then that should be okay.

thanks

Hi Jack,

To have more customization options and to  avoid the limits of automatically generated ComboBox column I would recommend the following approach :

Use GridViewDataColumn instead of GridViewComboBoxColumn. Set the CellTemplate Property to a custom template containing a ComboBox. Within the template you may set whatever property of the ComboBox as well as bind to specific ComboBox events in order to accomplish custom specific logic.

Hi Pavel,

   I am also having the same problem. If possible could you please send me some sample on this. Below is the code which i have written in my mehod. Please help me ASAP.

   Dim StatusList As New List(Of String)
      StatusList.Add("Projected")
      StatusList.Add("Scheduled")
      StatusList.Add("Completed")
      StatusList.Add("Approved")
      StatusList.Add("Skip Approved")
      StatusList.Add("Skip Denied")


      'Dim oComboBox As New Telerik.Windows.Controls.RadComboBox()
      'oComboBox.ItemsSource = StatusList
      'oComboBox.IsEditable = True



      Dim comboBoxEditorSettings As New Telerik.Windows.Controls.ComboBoxEditorSettings()
      comboBoxEditorSettings.ItemsSource = StatusList

      DirectCast(Me.grdProducts.Columns(5), GridViewDataColumn).EditorSettings = comboBoxEditorSettings

Hi,

Please see the sample app. attached.
It demonstrates a way to customize the automatically generated ComboBox utilizing the CellEditStyle property of the editor settings.

Hi Pavel,

  Thanks a lot for your help. It's gr8.
 
  I am requetsing you for your help. I am binding the RadTimePicker to the RadGridView and populating the data. 
  My problem is. I am able to select the Time from the control. Suppose if I moved out from that cell, the time is changing to previous time. it's now showing my selected time. Could you please help me on this.

Here I have attached my code. Please have a look in to this.

<telerik:GridViewDataColumn HeaderText="StartTime" DataFormatString="{}{0:t}" DataMemberBinding="{Binding BeginDateTime}" IsResizable="False">
  <telerik:GridViewDataColumn.CellTemplate>
    <DataTemplate>
        <TextBlock Text="{Binding BeginDateTime, Converter={StaticResource FormatConverter}, ConverterParameter=\{0:t\}}"  />
    </DataTemplate>
  </telerik:GridViewDataColumn.CellTemplate>
  <telerik:GridViewDataColumn.CellEditTemplate>
    <DataTemplate>
        <telerikInput:RadTimePicker SelectedTime="{Binding BeginDateTime}" />
    </DataTemplate>
  </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

Once again thanks for your help.

Thanks & Kind Regards

Hello satish,

You need to add Mode = TwoWay for this Binding - in Silverlight by default this is OneWay. Your business object also should implement INotifyPropertyChanged.

Hi Vlad,

 Thanks for the response. I did the same thing eventhough it's not showing the selected time in the grid. Could you please look the following code.

<telerik:GridViewDataColumn HeaderText="StartTime" DataFormatString="{}{0:t}" DataMemberBinding="{Binding BeginDateTime, Mode=TwoWay}" IsResizable="False">
      <telerik:GridViewDataColumn.CellTemplate>
       <DataTemplate>
           <TextBlock Text="{Binding BeginDateTime, Mode=TwoWay, Converter={StaticResource FormatConverter}, ConverterParameter=\{0:t\}}"  />
       </DataTemplate>
     </telerik:GridViewDataColumn.CellTemplate>
      <telerik:GridViewDataColumn.CellEditTemplate>
          <DataTemplate>
              <telerikInput:RadTimePicker SelectedTime="{Binding BeginDateTime, Mode=TwoWay}" />
         </DataTemplate>
     </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

Please help me.

Thanks & Regards
Satish

Hi satish,

If your only goal is to display the DateTime value as a time, you do not need to redefine the CellTemplate at all. The DataFormatString should be enough to tell the column to display its values formatted as time.

I have attached the sample project that the above code snippet is from.

Please, take a look at it and let me know if you have any other questions or if this is not what you are trying to achieve. If this is the case, can you please attach your original project.

Hello satish,

I could not quite catch what the exact issue is.

It will be best if you send me a sample project (or if it will be easier -- you can modify the project that I sent you) and explain in great detail what are you trying to achieve and what is the exact problem.

In this way I will be able to help you fix your project as quickly as possible. I am looking forward to hearing from you.

All the best,
Ross
