Answer 1

On datagridview mouseclick / cellcontent click 'events' provide code to get filled into textbox.

  textBox1.Text = datagridview.Cells[1].Value.ToString();

where '1' is cell index.

Answer 2

Try This..

 protected void btnSave_Click(object sender, EventArgs e) { if (btnSave.Text == "Save") { int ID = Convert.ToInt32(txtdriverId.Text); int name= Convert.ToInt32(txtdrivername.Text); string sqlstr = "insert into TB_DRIVER(driverId,drivername) values(" + ID + "," + name + ")"; SqlCommand cmd = new SqlCommand(sqlstr, con); con.Open(); int i = cmd.ExecuteNonQuery(); con.Close(); BindGrid(); btnSave.Text = "Save"; } if (btnSave.Text == "Update") { int ID = Convert.ToInt32(driverId.Text); int name= Convert.ToInt32(txtdrivername.Text); sqlstr = "update TB_DRIVER set driverId=" + ID + ", drivername=" + name + " where driverId=" + ID; SqlCommand cmd = new SqlCommand(sqlstr, con); con.Open(); int i = cmd.ExecuteNonQuery(); con.Close(); BindGrid(); btnSave.Text = "Save"; } } protected void GrdDrivers_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "Edit") { int ID = Convert.ToInt32(e.CommandArgument); ViewState["ID"] = ID; string str = "select * from TB_DRIVER where driverId = '" + ID + "'"; SqlCommand cmd = new SqlCommand(str, con); con.Open(); SqlDataReader dr = cmd.ExecuteReader(); if (dr.Read()) { txtdriverId.Text = dr[0].ToString(); txtdrivername.Text = dr[1].ToString(); } con.Close(); btnSave.Text = "Update"; } BindGrid(); } protected void GrdDrivers_RowEditing(object sender, GridViewEditEventArgs e) { } protected void GrdDrivers_RowDeleting(object sender, GridViewDeleteEventArgs e) { } public void BindGrid() { string sqlstr = "Select * from TB_DRIVER"; SqlDataAdapter da = new SqlDataAdapter(sqlstr, con); DataTable ds = new DataTable(); da.Fill(ds); GrdDrivers.DataSource = ds; GrdDrivers.DataBind(); } 

 <asp:GridView ID="GrdDrivers" runat="server" AutoGenerateColumns="false" HorizontalAlign="Center" OnRowCommand="GrdDrivers_RowCommand" OnRowDeleting="GrdDrivers_RowDeleting" OnRowEditing="GrdDrivers_RowEditing"> <Columns> <asp:TemplateField HeaderText="Driver ID"> <ItemTemplate> <asp:Label ID="lblDriverID" runat="server" Text='<%# Bind("DriverID") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Driver Name"> <ItemTemplate> <asp:Label ID="lblDrivername" runat="server" Text='<%# Bind("Drivername") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="lbtnEdit" runat="server" CommandName="Edit" Text="Edit" CommandArgument='<%# Eval("DriverID") %>'></asp:LinkButton> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> 

Answer 3

inside gridview button:

   <asp:LinkButton runat="server" ID="lnkEdit" OnClick="lnkEdit_Click" Text="Edit"></asp:LinkButton>

on cs page:

  protected void lnkEdit_Click(object sender, EventArgs e)
    {
        GridViewRow row = (GridViewRow)((LinkButton)sender).NamingContainer;

        txt1.Text = row.Cells[0].Text;
        txt2.Text = row.Cells[1].Text;
    }
