How to add the rows & columns in gridview problematically

n this tutorial i will show you that how can wee add rows & column in the gridview using coding or problematically
here are the steps....


1) Create a DataTable object to which than we will bind the GridView

DataTable dt = new DataTable();
2) IF you need two columns than create two DataColumn objects

DataColumn dc1 = new DataColumn("first", typeof(string));

DataColumn dc2 = new DataColumn("second", typeof(string));
DataColumn dc3 = new DataColumn("third", typeof(string));

Add it to the table

dt.Columns.Add(dc1);

dt.Columns.Add(dc2);
dt.Columns.Add(dc3);
3)Run the loop for as many rows you want to add. eg: 3 rows to be added.

for(int i=0;i<3;i++)// 3 = number of rows needed.

{
DataRow row1 = dt.NewRow();
int c = 0;
while (c < 3)
{
row1[c] = "some_data";
c++;
}
dt.Rows.Add(row1 );
}

Now iterate through each datacolumn and create a BoundField foreach column

foreach (DataColumn col in dt.Columns)

{
BoundField bField = new BoundField();
bField.DataField = col.ColumnName;
bField.HeaderText = col.ColumnName;
GridView1.Columns.Add(bField);
}

GridView1.DataSource = dt;
//Bind the datatable with the GridView.
GridView1.DataBind();
