How to create a basic ASP.NET GridView manually–Basic DataBinding

 

As I am working on some legacy systems and use to give support for them, where one cannot find predefined drag and drop controls, and somewhat have to tailor one for themselves.

Today I will share the experience of such practice with all of you (actually it is called manual data binding with a table using a Dataset object)

below is the code of an asp.net page

 

A simple page with only one table control as an example:

<asp:Table ID="tblPayment" runat="server" 
    Font-Names="arial, helvetica, sans-serif">
</asp:Table>

Now the code behind to bind a DataSet object might look alike below:

 

 trow = new TableRow();

            tcell = new TableCell();

            tcell.Width = 150;

            lblUserName = new Label();

            lblUserName.Text = "Name ";

            tcell.Controls.Add(lblUserName);

            trow.Cells.Add(tcell);

            // first cell finished

            // second cell

            tcell = new TableCell();

            tcell.Width = 5;

            lblColn = new Label();

            lblColn.Text = ":";

            tcell.Controls.Add(lblColn);

            trow.Cells.Add(tcell);

            // second cell finished

            // third cell

            tcell = new TableCell();

            lblName = new Label();

            userName = dsPaymentReceive.Tables[0].Rows[0]["username"].ToString();

            dsMember = new DataSet();

            gClsUserAdmin = new WSUserAdmin.WSUserAdmin();

            gClsGeneralFunction.SetUserAdminWebServiceUrl("WSUserAdmin.asmx", gClsUserAdmin);

            //string name = "";

            fName = dsPaymentReceive.Tables[0].Rows[0]["fname"].ToString();

            sName = dsPaymentReceive.Tables[0].Rows[0]["surname"].ToString();

            name = fName + " " + sName;

            lblName.Text = name.ToString();

            // End of Adding by ARYA 

            tcell.Controls.Add(lblName);

            trow.Cells.Add(tcell);

            //third cell

            tblPayment.Rows.Add(trow);

 

As above shows that we requested a DataSet Obj from a Service call, and then dynamically making new rows and cells, adding rows in the table defined in the aspx file.

 

We can do that in a for loop too  if the number of rows are greater than1.
