RadGridViewMaskBoxColumn - underscores appearing in field data after editing the field

[Lou]

Hi, I have a RadGridView with a GridViewMaskBoxColumn that I want to use to allow the user to be able to enter any text up to 16 characters.

I have the following settings at the moment for the GridViewMaskBoxColumn:

MaskType = Standard
Mask = &&&&&&&&&&&&&&&& 

When I double click on a cell I see that underscores are used to indicate spaces. That's fine, and I'm able to edit the data. However, the underscores are persisting in my data when I move my cursor to a different field (i.e. when I'm done editing).  In other words:

Data before editing: "12345678        "
View of data while editing: "12345678________"  (underscores used to indicate spaces)
Data after editing: "12345678________"  (underscores have become part of the data).

Is there a way to prevent this? I don't want the underscores to be in my data after I'm done editing it.

Thanks for any help,

-Lou

Hello Lou,

Thank you for writing.

The TextMaskFormat property controls whether the prompt characters will be included in the value. You can set this property to the column like this:

GridViewMaskBoxColumn col = new GridViewMaskBoxColumn();

col.TextMaskFormat = MaskFormat.IncludeLiterals;

Please let me know if there is something else I can help you with.

Hi Dimitar, this got me closer to what I need but I still have a problem.

With the setting you suggested (col.TextMaskFormat = MaskFormat.IncludeLiterals) I no longer get the underscores, which is good.

However, now when I type a space character as part of the string, that space is removed from the field.
So, the string "foo 123" becomes "foo123" when focus is lost from the field.
Is there a way to not have spaces removed? I want whatever I type to be reflected in the field value.

Thanks for your help,

Hello Lou,

Thank you for writing back.

I was able to reproduce the observed behaviour. Is is caused by an issue in our implementation. I have logged it in our Feedback Portal. You can track the item for status changes and add your vote for it here.

To workaround this issue you can create a custom editor:

public class MyRadMaskedEditBoxEditor : RadMaskedEditBoxEditor
{
    public override object Value
    {
        get
        {
            if (this.MaskTextBox.Mask == "&&&&&&&&&&")
            {
                return this.MaskTextBox.Value;
            }
            return base.Value;
        }
        set
        {
            base.Value = value;
        }
    }
}

You can change the default editor like this:

void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
{
    if (e.EditorType == typeof(RadMaskedEditBoxEditor))
    {
        e.EditorType = typeof(MyRadMaskedEditBoxEditor);
    }
}

Please note that you should change the value of the TextMaskFormat property to IncludeLiterals as well.

Your Telerik Points have been updated for this report.

Should you have any other questions do not hesitate to ask.

Thanks Dimitar, I implemented the fix and it seems to work.

Below is the equivalent code for the fix in VB.Net in case it's useful for others.

Modified control:

Imports Telerik.WinControls
Imports Telerik.WinControls.UI


Public Class MyRadMaskedEditBoxEditor
  Inherits RadMaskedEditBoxEditor

  Public Overrides Property Value As Object
    Get
      If (MyBase.MaskTextBox.Mask = "&&&&&&&&&&&&&&&&") Then
        Return MyBase.MaskTextBox.Value
      End If

      Return MyBase.Value
    End Get

    Set(value As Object)
      MyBase.Value = value
    End Set
  End Property
End Class

New handler:

Private Sub grd_EditorRequired(sender As System.Object, e As Telerik.WinControls.UI.EditorRequiredEventArgs) Handles grd.EditorRequired
  If e.EditorType Is GetType(RadMaskedEditBoxEditor) Then
    e.EditorType = GetType(MyRadMaskedEditBoxEditor)
  End If
End Sub
