textbox column with formated

Hi, Hengky,

In case you don't want to use a GridViewMaskBoxColumn , please have in mind that RadGridView offers the CellFormatting event which gives you the possibility to display any text in the cell by setting the CellElement.Text property to the desired text.

Thus, considering the cell's Value, you can format the CellElement.Text according to your needs.

I hope this information helps.

Hello, Hengky,

You can set any custom formatted text that you want to the Text property of the CellElement in CellFormatting event. For more information about formatting text please refer to the following MSDN articles:
https://docs.microsoft.com/en-us/dotnet/api/system.string.format?view=netcore-3.1 
https://docs.microsoft.com/en-us/dotnet/standard/base-types/custom-numeric-format-strings?redirectedfrom=MSDN#the--custom-specifier-1 
https://docs.microsoft.com/en-us/dotnet/api/system.string.substring?view=netcore-3.1 

Here is a sample demonstration:

 private void RadGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
 {
     if (e.CellElement.RowIndex > -1)
     {
         if (e.CellElement.ColumnIndex == 0)
         {
             e.CellElement.Text = string.Format("{0:##-##.00}", (double)e.CellElement.Value);
         }
         else
         {
             e.CellElement.ResetValue(LightVisualElement.TextProperty, ValueResetFlags.Local);
         }
     }
 }

I hope this helps. Should you need further assistance do not hesitate to ask.

if i just replace to .... , GridViewMaskedColun ... it;s getting error . 

Thanks Des... 

Hello, Hengky,   

If the column doesn't cast to GridViewMaskBoxColumn successfully, this means that it is most probably of another type, e.g. GridViewDecimalColumn. Please make sure that the column is the expected type before converting it to GridViewMaskBoxColumn. Otherwise, you can remove the already existing column and add a new one as below: 

        Me.RadGridView1.MasterTemplate.Templates(0).Columns.Remove("UnitPrice")
        Dim maskBoxColumn As New GridViewMaskBoxColumn() 
        maskBoxColumn.FieldName = "UnitPrice" 
        maskBoxColumn.MaskType = MaskType.Numeric
        maskBoxColumn.Mask = "C" 
        maskBoxColumn.FormatString = "{0:C}"
        maskBoxColumn.DataType = GetType(Decimal)
        Me.RadGridView1.MasterTemplate.Templates(0).Columns.Add(maskBoxColumn)

I have attached my sample project for your reference.
