    Width="100%">
           <Columns>
            <asp:BoundField DataField ="Name" HeaderText ="Employee_Name" ReadOnly="true" />
            <asp:BoundField DataField ="Employee_ID" HeaderText ="Emp_ID" ReadOnly="true"/>
            <asp:BoundField DataField ="Department" HeaderText ="Department" ReadOnly="true"/>
            <asp:BoundField DataField ="Designation" HeaderText ="Designation" ReadOnly="true"/>
           </Columns>
       </asp:GridView>

this is the click event in the button

protected void Button1_Click(object sender, EventArgs e)
{
    dept.Text=Deptdrop.SelectedItem.Text;
    desLabel.Text = Desigdrop.SelectedItem.Text;
    DataTable dt = new DataTable();
    this.showinfogrid.Visible = true;
    dt.Columns.Add("Name");
    dt.Columns.Add("Employee_ID");
    dt.Columns.Add("Department");
    dt.Columns.Add("Designation");
    dt.Rows.Add(nameTextBox1.Text.Trim(), empidTextBox2.Text.Trim(), Deptdrop.SelectedItem.Text, Desigdrop.SelectedItem.Text);
    showinfogrid.DataSource = dt;
    showinfogrid.DataBind();

See this link : Dynamically adding and deleting rows from ASP.NET GridView[^]. It is all about what you are looking for.

Further,as suggested by Karthik[^],wrap your code inside update panel.

Check up this tutorial:

http://www.aspsnippets.com/Articles/Adding-Dynamic-Rows-in-ASP.Net-GridView-Control-with-TextBoxes.aspx[^]

To prevent page from being refreshed, add the gridview into UpdatePanel control.

Solution 1

Use the below code to add the new row in gridview.

C#

//showinfogrid.Rows[0].Cells.Clear();//clear the gird data
showinfogrid.Rows[0].Cells.Add(new TableCell()); 
showinfogrid.Rows[0].Cells[0].ColumnSpan = TotalColumns;// to merge
showinfogrid.Rows[0].Cells[0].Text = "No Record Found";

u can add the that code in "Button1_Click" event.

Note: If the data is available, add that code after binding or if the data not available add this code after adding the columns.

Hi

Put all your controls in an ajax update panel and try it..

sample code:

XML

<asp:UpdatePanel ID="up" runat="server">
        <ContentTemplate>
            <asp:ScriptManager ID="ScriptManager1" runat="server">
            </asp:ScriptManager>
            <asp:GridView ID="showinfogrid" runat="server" AutoGenerateColumns="False" Width="100%">
                <Columns>
                    <asp:BoundField DataField="Name" HeaderText="Employee_Name" ReadOnly="true" />
                    <asp:BoundField DataField="Employee_ID" HeaderText="Emp_ID" ReadOnly="true" />
                    <asp:BoundField DataField="Department" HeaderText="Department" ReadOnly="true" />
                    <asp:BoundField DataField="Designation" HeaderText="Designation" ReadOnly="true" />
                </Columns>
            </asp:GridView>
            <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
        </ContentTemplate>
    </asp:UpdatePanel>
