GridViewDecimalColumn

GridViewDecimalColumn allows decimal data to be displayed and edited. GridViewDecimalColumn can be bound to fields of any numeric type.

Add GridViewDecimalColumn to the grid.

• C#
• VB.NET

GridViewDecimalColumn decimalColumn = new GridViewDecimalColumn();
decimalColumn.Name = "DecimalColumn";
decimalColumn.HeaderText = "Unit Price";
decimalColumn.FieldName = "UnitPrice";
decimalColumn.DecimalPlaces = 3;
radGridView1.MasterTemplate.Columns.Add(decimalColumn);

Dim decimalColumn As New GridViewDecimalColumn()
decimalColumn.Name = "DecimalColumn"
decimalColumn.HeaderText = "Unit Price"
decimalColumn.FieldName = "UnitPrice"
decimalColumn.DecimalPlaces = 3
RadGridView1.MasterTemplate.Columns.Add(decimalColumn)

Setting a default value for empty cells

You may provide a default value using the following code:

• C#
• VB.NET

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    GridSpinEditor spinEditor = this.radGridView1.ActiveEditor as GridSpinEditor;
    if (spinEditor != null)
    {
        if (spinEditor.Value == null)
        {
            spinEditor.Value = 0.0;
        }
    }
}

Private Sub RadGridView1_CellEditorInitialized(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs)
    Dim spinEditor As GridSpinEditor = TryCast(Me.RadGridView1.ActiveEditor, GridSpinEditor)
    If spinEditor IsNot Nothing Then
        spinEditor.Value = 0
    End If
End Sub

 Disable the up and down buttons of the spin editor

The code below demonstrates how you can disable the up and down arrow buttons. Using the commented code you can completely hide them.

• C#
• VB.NET

void radGridView1_CellEditorInitialized1(object sender, GridViewCellEventArgs e)
{
    GridSpinEditor spinEditor = this.radGridView1.ActiveEditor as GridSpinEditor;
    ((RadSpinEditorElement)spinEditor.EditorElement).ShowUpDownButtons = false;
}

Private Sub RadGridView1_CellEditorInitialized1(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs)
    Dim spinEditor As GridSpinEditor = TryCast(Me.RadGridView1.ActiveEditor, GridSpinEditor)
    If spinEditor IsNot Nothing Then
        Dim element As RadSpinEditorElement = spinEditor.EditorElement
        element.ShowUpDownButtons = False
    End If
End Sub

Setting decimal places

The rich API of RadGridView allows you to define one value for the decimal places that should be shown in the spin editor of the column and another value for the cells of the column.

Setting decimal places to the spin editor

You can define how many places after the decimal point the value in the spin editor should have by setting the DecimalPlaces property of GridViewDecimalColumn:

• C#
• VB.NET

decimalColumn.DecimalPlaces = 3;

decimalColumn.DecimalPlaces = 3

Setting decimal places to the column cells

In order to define how the values should be displayed by the cells of the GridViewDecimalColumn in the sense of their decimal places, we should set the FormatString property of the column:

• C#
• VB.NET

decimalColumn.FormatString = "{0:N2}";

decimalColumn.FormatString = "{0:N2}"
