    Hi to all,

    I would use same format to edit column and visual column for percent value

    I'm using formatstring "{0:P2}" to show percent value correctly (value passed by object is for example 0.06), this formatstring show me 6%, OK!

    But when I edit cell it shows me 0.06, are ther a way to edit value "6%", keeping 0.06 into my object?


    Then my data is 0.06, it shows 6 %, I enter in edit mode and It should show me "6" or "6 %" (masked? I don't know),

    I enter 6.5 %, and it store in my data 0.065

    Is it possible?

    01.Dim _Column As New GridViewDecimalColumn()
    03._Column.AutoSizeMode = BestFitColumnMode.AllCells
    04._Column.HeaderText = "Percentage"
    05._Column.FieldName = "Discount"
    06._Column.Name = "Perc01"
    07._Column.Width = 100
    08._Column.FormatString = "{0:P2}"
    09._Column.DecimalPlaces = 2
    10._Column.ThousandsSeparator = False

    Hello Potito,

    Thank you for writing. 

    GridViewDecimalColumn uses a spin editor which displays only numeric values. If you need to format the editor to display the percentage sign, I would recommend you to use a GridViewMaskBoxColumn:
    Dim maskBoxColumn As New GridViewMaskBoxColumn("%")     
    maskBoxColumn.MaskType = MaskType.Numeric
    maskBoxColumn.Mask = "P"
    maskBoxColumn.FormatString = "{0:P}"
    maskBoxColumn.DataType = GetType(Decimal)
    For index = 1 To 10
        Me.RadGridView1.Rows.Add(index * 0.1)

    I hope this information helps. Should you have further questions I would be glad to help.
