Hi Frank,

 

Thanks for using Syncfusion Products.

 

Query:

Formatting Numeric Columns in a GridDataBoundGrid

You can just change the cell type for the columns in your databound grid.

For example.

this.gdbs.Binder.InternalColumns[1].StyleInfo.CellType = "Static";.

 

 For your specific cell type, you could use NumericUpDown, Currency, MaskedEdit, or even Static(if you format your value before you set it)

 

In addition to setting the CellType property,

 this.gdb.Binder.InternalColumns[1].StyleInfo.CellType,

you can also set the Format property and the CellValueTyle property.

 

 this.gdb.Binder.InternalColumns[1].StyleInfo.Format = "#.####"; //or "F4" or ???

this.gdb.Binder.InternalColumns[1].StyleInfo.CellValueType = typeof(double).

 

 

Please let us know, if you any concerns.

 

Regards,

ManiRatheenam S

Hello,

Hello,


I think that have a good solution:


With GridBound

  ' --- term to text ---

  .Binder.InternalColumns("steMyField01").StyleInfo.CellType = "Static"

  .Binder.InternalColumns("steMyField01").StyleInfo.CellValueType = GetType(System.String)

  ' --- byte to boolean

  .Binder.InternalColumns("steMyField02").StyleInfo.CellType = "CheckBox"

  .Binder.InternalColumns("steMyField02").StyleInfo.CellValueType = GetType(System.Boolean)

End With



My problem:

The value of the column 'steMyField02' in the database is 0 and 1 (Type Byte).


When I set:


  .Binder.InternalColumns("steMyField02").StyleInfo.CellType = "Static"

  .Binder.InternalColumns("steMyField02").StyleInfo.CellValueType = GetType(System.Boolean)

  

I get as result False and True in the grid but when I set: 


  .Binder.InternalColumns("steMyField02").StyleInfo.CellType = "CheckBox"

  .Binder.InternalColumns("steMyField02").StyleInfo.CellValueType = GetType(System.Boolean)

  

I get as result only unchecked fields!?


Have you the solution for right way?


Best regards,

Hi Frank,

 

Thanks for the update.

 

The reported scenario can be achieved by using “CheckBoxOptions” property. Please refer the code,

 

Code:

Me.gridDataBoundGrid1.Model.ColStyles(1).CellType = GridCellTypeName.[Static]

Me.gridDataBoundGrid1.Model.ColStyles(1).CellValueType = GetType(Boolean)

 

Me.gridDataBoundGrid1.Model.ColStyles(1).CheckBoxOptions = New GridCheckBoxCellInfo("1", "0", "", True)

Me.gridDataBoundGrid1.Model.ColStyles(1).CellType = GridCellTypeName.CheckBox

Me.gridDataBoundGrid1.Model.ColStyles(1).CellValueType = GetType(Boolean)

 

Please let us know if you have any concern.

 

Regards,

Muthukumar K

Hi Muthukumar,

excellent, your example works not (at my project) but it shows me the solution.

At my project works this:

Me.gridDataBoundGrid1.Binder.InternalColumns(1).StyleInfo.CheckBoxOptions = New GridCheckBoxCellInfo("1", "0", "", True)
Me.gridDataBoundGrid1.Binder.InternalColumns(1).StyleInfo.CellType = "CheckBox"
Me.gridDataBoundGrid1.Binder.InternalColumns(1).StyleInfo.CellValueType = GetType(System.Boolean)

Many thanks!
