Hi

  I have below Gridview. There is value in Session Date but it is showing ""

<div class="table-responsive">
                                        <asp:GridView ID="grdPlanning" class="table table-bordered" runat="server" OnRowDataBound="gr_RowDataBound" OnRowCommand="grdPlanning_RowCommand" AutoGenerateColumns="true">
                                            <Columns>
                                                <asp:TemplateField HeaderText="Session Date">
                                                    <ItemTemplate>
                                                        <asp:TextBox ID="txtSessionDate" runat="server" CssClass="form-control daterange-single" Text=''></asp:TextBox>
                                                    </ItemTemplate>
                                                </asp:TemplateField>
                                            </Columns>
                                        </asp:GridView>
                                    </div>

foreach (GridViewRow gr in grdPlanning.Rows)
                {
                    if (gr.RowType == DataControlRowType.DataRow)
                    {
                        if (gr.Cells[0].Enabled == true)
                        {
                            sessionDate = (gr.FindControl("txtSessionDate") as TextBox).Text.Trim();
}
}
}

Thanks
