Set autogenerated GridView cell value in 2 Decimal place using C# and VB.Net in ASP.Net

Hi rakeshkuma,

You need to loop through all the cells and check if decimal value then round to 2 decimal.

Refer below sample.

HTML

<asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="true" OnRowDataBound="OnRowDataBound">
    <Columns></Columns>
</asp:GridView>

Code

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        System.Data.DataTable dt = new System.Data.DataTable();
        dt.Columns.AddRange(new System.Data.DataColumn[3]
        {
            new System.Data.DataColumn("Id",typeof(int)),
            new System.Data.DataColumn("Name",typeof(string)),
            new System.Data.DataColumn("Price",typeof(decimal))
        });
        dt.Rows.Add(1, "Apple", "120.225");
        dt.Rows.Add(2, "Banana", "48.569");
        dt.Rows.Add(3, "Orange", "50");
        this.GridView1.DataSource = dt;
        this.GridView1.DataBind();
    }
}

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        for (int i = 0; i < e.Row.Cells.Count; i++)
        {
            decimal value;
            if (decimal.TryParse(e.Row.Cells[i].Text.Trim(), out value))
            {
                e.Row.Cells[i].Text = Math.Round(value, 2).ToString();
            }
        }
    }
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim dt As Data.DataTable = New Data.DataTable()
        dt.Columns.AddRange(New Data.DataColumn(2) {
                            New Data.DataColumn("Id", GetType(Integer)),
                            New Data.DataColumn("Name", GetType(String)),
                            New Data.DataColumn("Price", GetType(Decimal))})
        dt.Rows.Add(1, "Apple", "120.225")
        dt.Rows.Add(2, "Banana", "48.569")
        dt.Rows.Add(3, "Orange", "50")
        Me.GridView1.DataSource = dt
        Me.GridView1.DataBind()
    End If
End Sub

Protected Sub OnRowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    If e.Row.RowType = DataControlRowType.DataRow Then
        For i As Integer = 0 To e.Row.Cells.Count - 1
            Dim value As Decimal
            If Decimal.TryParse(e.Row.Cells(i).Text.Trim(), value) Then
                e.Row.Cells(i).Text = Math.Round(value, 2).ToString()
            End If
        Next
    End If
End Sub
