You can use "DataFormatString" property in asp:BoundField to format the date fields. Here is the sample code

ASP.NET

<asp:gridview id="GridView1" runat="server" xmlns:asp="#unknown">
    <columns>
        <asp:boundfield datafield="JoinDate" dataformatstring="{0: dd-MM-yyyy hh:mm tt }" />
    </columns>
    </asp:gridview>

you can also use the source code to change the date format using Gridviews RowDataBound event. Find the template control for your date and then convert the date to your required format in this event.

Here is the aspx code
<pre lang="HTML">
<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server"
onrowdatabound="GridView1_RowDataBound">
<columns>
<%--<asp:BoundField DataField="JoinDate" DataFormatString="{0: dd-MM-yyyy hh:mm tt }" />--%>
<asp:TemplateField HeaderText="Joining date">
<itemtemplate>
<asp:Label ID="lblJoinDate" Text='<%#Eval("joindate") %>' runat="server" />

</pre>

and this is the code behind in c#
<pre lang="c#">
protected void Page_Load(object sender, EventArgs e)
{
GridView1.DataSource = createDataSource();
GridView1.DataBind();
}

private DataTable createDataSource()
{
DataTable dt = new DataTable();
dt.Columns.Add("JoinDate", typeof(DateTime));
dt.Rows.Add(DateTime.Now);
return dt;
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblJoinDate = (Label)e.Row.FindControl("lblJoinDate");
DateTime joindate = Convert.ToDateTime(lblJoinDate.Text);
lblJoinDate.Text = joindate.ToString("dd-MM-yyyy hh:mm:ss tt");
}
}
</pre>

Hope it will help you

XML

Here is the aspx code
<pre lang="HTML">
<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server"
        onrowdatabound="GridView1_RowDataBound">
    <Columns>
        <%--<asp:BoundField DataField="JoinDate" DataFormatString="{0: dd-MM-yyyy hh:mm tt }" />--%>
        <asp:TemplateField HeaderText="Joining date">
            <ItemTemplate>
                <asp:Label ID="lblJoinDate" Text='<%#Eval("joindate") %>' runat="server" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
    </asp:GridView>
</pre>

and this is the code behind in c#
<pre lang="c#">
protected void Page_Load(object sender, EventArgs e)
    {
        GridView1.DataSource = createDataSource();
        GridView1.DataBind();
    }

    private DataTable createDataSource()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("JoinDate", typeof(DateTime));
        dt.Rows.Add(DateTime.Now);
        return dt;
    }
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            Label lblJoinDate = (Label)e.Row.FindControl("lblJoinDate");
            DateTime joindate = Convert.ToDateTime(lblJoinDate.Text);
            lblJoinDate.Text = joindate.ToString("dd-MM-yyyy hh:mm:ss tt");
        }
    }
</pre>
