How to set default value to TimeSelector inside GridView when value is null using C# and VB.Net in ASP.Net

Hi pir,

There is no concept of viewing empty data. You can assign 0 so that it will display as 12:00:00 AM

HTML

<div>
    <asp:ScriptManager runat="server" />
    <asp:GridView runat="server" ID="GridView1" OnRowDataBound="DataBound" AutoGenerateColumns="false">
        <Columns>
            <asp:BoundField DataField="Id" HeaderText="Id" />
            <asp:BoundField DataField="Name" HeaderText="Name" />
            <asp:TemplateField HeaderText="Time">
                <ItemTemplate>
                    <asp:HiddenField ID="hfTime" runat="server" Value='<%#Eval("COME_OUT") %>' />
                    <cc1:TimeSelector ID="tsTime" runat="server">
                    </cc1:TimeSelector>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
</div>

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)), new DataColumn("Name"), new DataColumn("COME_OUT") });
        dt.Rows.Add(1, "John Hammond", "12:35 PM");
        dt.Rows.Add(2, "Mudassar Khan", "12:35 AM");
        dt.Rows.Add(3, "Suzanne Mathews", "");
        dt.Rows.Add(4, "Robert Schidner", "08:35 PM");
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}

protected void DataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        string hfTime = (e.Row.Cells[2].FindControl("hfTime") as HiddenField).Value;
        MKB.TimePicker.TimeSelector tsTime = e.Row.FindControl("tsTime") as MKB.TimePicker.TimeSelector;
        MKB.TimePicker.TimeSelector.AmPmSpec am_pm;
        if (hfTime == "")
        {
            tsTime.SetTime(0, 0, 0);
        }
        else
        {
            DateTime dt = DateTime.Parse(hfTime);
            if (dt.ToString("tt") == "AM")
            {
                am_pm = MKB.TimePicker.TimeSelector.AmPmSpec.AM;
            }
            else
            {
                am_pm = MKB.TimePicker.TimeSelector.AmPmSpec.PM;
            }
            tsTime.SetTime(dt.Hour, dt.Minute, am_pm);
        }
    }
}

VB.Net

Protected Sub Page_Load(sender As Object, e As EventArgs)
	If Not Me.IsPostBack Then
		Dim dt As New DataTable()
		dt.Columns.AddRange(New DataColumn(2) {New DataColumn("Id", GetType(Integer)), New DataColumn("Name"), New DataColumn("COME_OUT")})

		GridView1.DataBind()
	End If
End Sub

Protected Sub DataBound(sender As Object, e As GridViewRowEventArgs)
	If e.Row.RowType = DataControlRowType.DataRow Then
