Set default date on TextBox inside ASP.Net GridView using C# and VB.Net

Hi lingers,

It can be done in two ways.

1. Using ASPX page

HTML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Font-Names="Candara" Width="100%">
    <Columns>
        <asp:BoundField DataField="orderid" HeaderText="id" ItemStyle-Width="30" />
        <asp:BoundField DataField="purchaseorderno" HeaderText="PO NO" ItemStyle-Width="100" />
        <asp:BoundField DataField="quantity" HeaderText="Quantity" />
        <asp:TemplateField HeaderText="Date" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:TextBox ID="txtdate" runat="server" Width="200"
                    Text='<%#DateTime.Today.ToString("MM/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture) %>'></asp:TextBox>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Waybill">
            <ItemTemplate>
                <asp:TextBox ID="txtwaybill" runat="server" Width="100"></asp:TextBox>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Comment">
            <ItemTemplate>
                <asp:TextBox ID="txtcomment" runat="server" Width="100"></asp:TextBox>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Baseno" ItemStyle-Width="200">
            <ItemTemplate>
                <ul id="myTags" class="myTags">
                </ul>
                <asp:HiddenField ID="hfIds" runat="server" />
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
    </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("orderid"),
            new System.Data.DataColumn("purchaseorderno"),
            new System.Data.DataColumn("quantity") });
        dt.Rows.Add(1, 11, 10);
        dt.Rows.Add(2, 12, 5);
        dt.Rows.Add(3, 13, 17);
        dt.Rows.Add(4, 14, 8);
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}

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("orderid"),
                            New Data.DataColumn("purchaseorderno"),
                            New Data.DataColumn("quantity")})
        dt.Rows.Add(1, 11, 10)
        dt.Rows.Add(2, 12, 5)
        dt.Rows.Add(3, 13, 17)
        dt.Rows.Add(4, 14, 8)
        GridView1.DataSource = dt
        GridView1.DataBind()
    End If
End Sub

2. Using OnRowDataBound event

HTML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Font-Names="Candara" Width="100%"
    OnRowDataBound="OnRowDataBound">
    <Columns>
        <asp:BoundField DataField="orderid" HeaderText="id" ItemStyle-Width="30" />
        <asp:BoundField DataField="purchaseorderno" HeaderText="PO NO" ItemStyle-Width="100" />
        <asp:BoundField DataField="quantity" HeaderText="Quantity" />
        <asp:TemplateField HeaderText="Date" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:TextBox ID="txtdate" runat="server" Width="200"></asp:TextBox>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Waybill">
            <ItemTemplate>
                <asp:TextBox ID="txtwaybill" runat="server" Width="100"></asp:TextBox>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Comment">
            <ItemTemplate>
                <asp:TextBox ID="txtcomment" runat="server" Width="100"></asp:TextBox>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Baseno" ItemStyle-Width="200">
            <ItemTemplate>
                <ul id="myTags" class="myTags">
                </ul>
                <asp:HiddenField ID="hfIds" runat="server" />
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" />
        </asp:TemplateField>
    </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("orderid"),
            new System.Data.DataColumn("purchaseorderno"),
            new System.Data.DataColumn("quantity") });
        dt.Rows.Add(1, 11, 10);
        dt.Rows.Add(2, 12, 5);
        dt.Rows.Add(3, 13, 17);
        dt.Rows.Add(4, 14, 8);
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        (e.Row.FindControl("txtdate") as TextBox).Text = 
            DateTime.Today.ToString("MM/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture);
    }
}

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("orderid"),
                            New Data.DataColumn("purchaseorderno"),
                            New Data.DataColumn("quantity")})
        dt.Rows.Add(1, 11, 10)
        dt.Rows.Add(2, 12, 5)
        dt.Rows.Add(3, 13, 17)
        dt.Rows.Add(4, 14, 8)
        GridView1.DataSource = dt
        GridView1.DataBind()
    End If
End Sub

Protected Sub OnRowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    If e.Row.RowType = DataControlRowType.DataRow Then
        TryCast(e.Row.FindControl("txtdate"), TextBox).Text = 
            DateTime.Today.ToString("MM/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture)
    End If
End Sub
