Data of different type in the same column

[jeremy]

Hi,
   One column which type is GridViewMaskedTextBoxColumn in my Columns of RadGridView, User can input data of  three types, string like "22232//abcd", integar like 123, double like 123.00. I user PreparingCellForEdit Event to initialize the EditingElement which is RadMaskedTextBox,

private void rgv_PreparingCellForEdit(object sender, GridViewPreparingCellForEditEventArgs e)

       {

           if (e.Column.UniqueName == "IsRadMaskedTextBoxColumn")

           {

               RadMaskedTextBox tbNumbersArea = e.EditingElement as RadMaskedTextBox;

               

               if (e.Row.DataContext != null && e.Row.DataContext is CustSetbihyoItem)

               {

                   CustSetbihyoItem custItem = e.Row.DataContext as CustSetbihyoItem;

                   if (custItem.Unit == DicUnit[0] || custItem.Unit == DicUnit[2])


                   {

                       tbNumbersArea.MaskType = MaskType.Numeric;  //Input integer


                       tbNumbersArea.Mask = "d";

                       tbNumbersArea.Value = 1;

                   }

                   else if (custItem.Unit == DicUnit[10])

                   {

                       RwNumberArea RwNumberArea = new RwNumberArea();  //One child window be show


                       RwNumberArea.ShowDialog();

                   }

                   else 

                   {

                       tbNumbersArea.MaskType = MaskType.Numeric;  // Input Double


                       tbNumbersArea.Mask = "n2";

                       tbNumbersArea.Value = Menseki;  //the default is 100.00


                   }

                }

           }

       }

when I input the 200.00 according to the third condition(look the code), the  mask of RadMaskedTextbox is "n2", but when I finish editing , it displays 200, I need 200.00, how to solve it ?
Kind Regards

Hi jeremy,

This would be the expected behavior since the mask type is defined only for the editing element. In fact the GridViewMaskedTextBoxColumn ensures that the RadMaskedTextBox will be used while in edit-mode, not in view-mode. What you may try to do is to set the DataFormatString property of the column:

<telerik:GridViewMaskedTextBoxColumn UniqueName="RadMaskedTextBoxColumn"
                                   DataMemberBinding="{Binding StadiumCapacity}"
                                   DataFormatString="{}{0:N2}"/>

On a side note, I would recommend you to set value using the underlaying data item's properties, not by using a visual element - the editing element in this case. 

Best wishes,
