I'm using RadGridView sample you have been provided called "209935_editablecomboingridviewaddingitems-sl"

I'm trying to add the string "C,M" to the combo box but if i'll press enter the selected item "C,M,Y,K" will be set, and not the new item I want to add.
How can I solve this issue???

 

<UserControl.Resources>
        <local:MyConverter x:Key="MyConverter" />
        <Style  x:Name="myStyle" TargetType="telerik:RadComboBox">
            <Setter Property="OpenDropDownOnFocus" Value="True"/>
            <Setter Property="IsFilteringEnabled" Value="True" />
            <Setter Property="CanAutocompleteSelectItems" Value="False" />
        </Style>
  
    </UserControl.Resources>
  
    <Grid x:Name="LayoutRoot" Background="White">
        <telerik:RadGridView x:Name="RadGridView1" AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewComboBoxColumn UniqueName="MyNumber" IsComboBoxEditable="True" 
                                                DataMemberBinding="{Binding MyNumber, Converter={StaticResource MyConverter}}" />
  
                <telerik:GridViewComboBoxColumn UniqueName="MyString" IsComboBoxEditable="True" EditorStyle="{StaticResource myStyle}"
                                                DataMemberBinding="{Binding MyString}" />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

Hi Shirly,

What you need to do is to manually set the SelectedItem of the ComboBox right after the new Item is added. This way you will be able to avoid that behavior. I found the mentioned project and modified it in order to achieve the desired scenario, please check the attachment.

Hope this work for you.
