how can I fill gridview dynamic with textboxes ,dropdownlists ?

public partial class _Default : System.Web.UI.Page

{

#region constants

const string NAME NAME ;

const string ID ID ;

#endregion


protected void Page_Load(object sender EventArgs e)

{

loadDynamicGrid();

}


private void loadDynamicGrid()

{

#region Code for preparing the DataTable


//Create an instance of DataTable

DataTable dt new DataTable();


//Create an ID column for adding to the Datatable

DataColumn dcol new DataColumn(ID typeof(System.Int32));

dcol.AutoIncrement true;

dt.Columns.Add(dcol);


//Create an ID column for adding to the Datatable

dcol new DataColumn(NAME typeof(System.String));

dt.Columns.Add(dcol);


//Now add data for dynamic columns

//As the first column is auto-increment we do not have to add any thing.

//Let's add some data to the second column.

for (int nIndex 0; nIndex < 10; nIndex++)

{

//Create a new row

DataRow drow dt.NewRow();


//Initialize the row data.

drow[NAME] Row- + Convert.ToString((nIndex + 1));


//Add the row to the datatable.

dt.Rows.Add(drow);

}

#endregion


//Iterate through the columns of the datatable to set the data bound field dynamically.

foreach (DataColumn col in dt.Columns)

{

//Declare the bound field and allocate memory for the bound field.

BoundField bfield new BoundField();


//Initalize the DataField value.

bfield.DataField col.ColumnName;


//Initialize the HeaderText field value.

bfield.HeaderText col.ColumnName;


//Add the newly created bound field to the GridView.

GrdDynamic.Columns.Add(bfield);

}


//Initialize the DataSource

GrdDynamic.DataSource dt;


//Bind the datatable with the GridView.

GrdDynamic.DataBind();

}
