GridViewMaskBoxColumn negative values

[gabi]

I write the program in VB.
I have a RadGrid with some GridViewMaskBoxColumns with Mask="n3" and MaskType=Numeric.
When i put negative values in that cell afer i finish the edit the minus symbol disappears.
How can i put negative values in those cells?

Hello gabi,

There is an issue which concerns the usage of negative values in a numeric GridViewMaskBoxColumn. We will address it in a future version.

You can workaround the issue by using a custom RadMaskedEditBoxEditor. Please create it as discussed in this forum thread. Use the following code to handle the minus symbol:

public override void BeginEdit()
{
    base.MaskTextBox.KeyUp += new KeyEventHandler(MaskTextBox_KeyUp);
    base.BeginEdit();
}

public override bool EndEdit()
{
    base.MaskTextBox.KeyUp -= new KeyEventHandler(MaskTextBox_KeyUp);
    return base.EndEdit();
}

void MaskTextBox_KeyUp(object sender, KeyEventArgs e)
{
    if (e.KeyValue == 109)
    {
        base.MaskTextBox.MaskEditValue = -Convert.ToDecimal(base.MaskTextBox.MaskEditValue);
    }
}

I hope this helps.
