Hello. I'm new to using Telerik and I'm experiencing strange behavior when editing data in the RadGridView control. I have a GridViewMaskedInputColumn and I lose the first character if I start editing the content of the cell by pressing 2 or more keys in quick succession. I've searched and searched these forums (as well as Telerik's guides and Google), but I could not find anything that helped. Please forgive me if I overlooked something.

My project currently using version 2018.1.122.45 of Telerik's WPF suite. 

Here's a snippet of my XAML, please let me know if more detail is needed. 

<telerik:RadGridView Name="MainGridView"
                   AutoGenerateColumns="False"
                   CanUserDeleteRows="False"
                   CanUserInsertRows="False"
                   CanUserReorderColumns="True"
                   CellValidating="MainGridView_CellValidating"
                   IsBusy="{Binding IsGridRefreshing}"
                   IsFilteringAllowed="False"
                   IsSynchronizedWithCurrentItem="True"
                   EditTriggers="TextInput"
                   RowIndicatorVisibility="Collapsed"
                   SelectionMode="Single"
                   SelectionUnit="FullRow"
                   ShowGroupPanel="False"
                   ShowSearchPanel="True"
                   ItemsSource="{Binding Path=DetailGridVM.TblDetailGrid}"
                   SelectedItem="{Binding Path=DetailGridVM.SelectedDetail, Mode=TwoWay}">
     
        <telerik:GridViewMaskedInputColumn Header="Vendor Number"
                                          Mask=">a6"
                                          MaskType="Standard"
                                          Name="GV_Column_VendorNumber"
                                          Width="65"
                                          DataMemberBinding="{Binding VendorNumber, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
 
            <telerik:GridViewMaskedInputColumn.HeaderCellStyle>
                <Style TargetType="telerik:GridViewHeaderCell">
                    <Setter Property="TextAlignment" Value="Center"/>
                    <Setter Property="TextWrapping" Value="Wrap"/>
                    <Setter Property="Background" Value="#FF9AE1B4"/>
                    <Setter Property="Foreground" Value="Black"/>
                </Style>
            </telerik:GridViewMaskedInputColumn.HeaderCellStyle>
             
            <telerik:GridViewMaskedInputColumn.EditorStyle>
                <Style TargetType="telerik:RadMaskedTextInput">
                    <Setter Property="SelectionOnFocus" Value="SelectAll"/>
                </Style>
            </telerik:GridViewMaskedInputColumn.EditorStyle>
        </telerik:GridViewMaskedInputColumn>
     
</telerik:RadGridView>

 

Please note that the "Mask" property for the column object doesn't actually contain the ">" sign. It uses the correct notation as demonstrated in Telerik's guide, I just can't figure out how to escape it in this forum. 

Thank you for any assistance.

Hello Alex,

Thank you for the provided code snippet. I can confirm that I was able to replicate the undesired behavior at my end.

This does seem like a bug at our end and I have thus logged a new bug report in our feedback portal regarding it. As a thank you for your help in addressing it, I've awarded you with some Telerik points.

I'm afraid, however, that I cannot offer a viable workaround at this point. What I can suggest is to follow the feedback item to get notified once a fix for this issue is introduced.

Nonetheless, if I can be of any other assistance, please let me know.

Regards,
Dilyan Traykov
