Hide column of Gridview and change its Header text on Condition

Hide column of Gridview and change its Header text on Condition

Step 1:-Design web from .aspx page

   <div>

            <asp:GridView ID="gr" runat="server" AutoGenerateColumns="false" AlternatingRowStyle-BackColor="WhiteSmoke" Width="40%" OnRowDataBound="gr_RowDataBound">

                <HeaderStyle BackColor="#3366ff" Font-Bold="true" ForeColor="White" />

                <Columns>

                    <asp:TemplateField HeaderText="Name">

                        <ItemTemplate>

                            <asp:Label ID="lbl_Name" runat="server" Text='<%#Eval("Name") %>'></asp:Label>

                        </ItemTemplate>

                    </asp:TemplateField>

                    <asp:BoundField DataField="City" HeaderText="City" />

                    <asp:BoundField DataField="Phone" HeaderText="Phone" />

                    <asp:TemplateField HeaderText="Percentage">

                        <ItemTemplate>

                            <asp:Label ID="lbl_Perc" runat="server" Text='<%#Eval("percentage") %>'></asp:Label>

                        </ItemTemplate>

                    </asp:TemplateField>

                </Columns>

            </asp:GridView>

        </div>

 Step 2:-Logic on .CS page

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            //Bind Gridview

            bind_gr();

        }

       

    }

    public void bind_gr()

    {

        DataTable dt = new DataTable();

        dt.Columns.Add("Name");

        dt.Columns.Add("City");

        dt.Columns.Add("Phone");

        dt.Columns.Add("percentage");

        dt.Rows.Add("Kandy", "Delhi", "8802***2564", "54");

        dt.Rows.Add("Sam", "Hr", "545502*2544", "32");

        dt.Rows.Add("Izhar", "Up", "95802*2452", "90");

        dt.Rows.Add("Vineet", "Delhi", "88022564***", "31");

       

        gr.DataSource = dt;

        gr.DataBind();

    }

    protected void gr_RowDataBound(object sender, GridViewRowEventArgs e)

    {

        if (e.Row.RowType == DataControlRowType.DataRow)

        {

            //Hiding fourth coloum of griodview...

            gr.Columns[3].Visible = false;

           

            //Changing header text of first coloum

            gr.HeaderRow.Cells[0].Text = "kandy";

        }

    }

It will Look like :-
