Hello Team,

I have GridView on my page with following columns -
Emp_ID,
Emp_Name,
Emp_DOB

I have below code to refresh the same-

qry = "SELECT Emp_ID, Emp_Name, Emp_DOB FROM Employee_Master";
SqlCon.Open();
SqlDataAdapter adp = new SqlDataAdapter(qry, SqlCon);
System.Data.DataTable dt = new System.Data.DataTable();
adp.Fill(dt);
GridView1.DataSource = GetData();            
GridView1.DataBind();        
SqlCon.Close();

Problem : When I execute this - It will Create New Columns in GridView.
How I Want: I want to populate data to exesting columns only, which I have created in my gridview. This will help me to maintain the formatting such as Field Width, Wrap Text, etc.

Please help!!!!

Set AutoGenerateColumns="false" and then define columns in your grid with mappings to the fields expected to be shown. This way, even if the datasource has new fields it will not affect the grid. Grid will bind only those fields that you have mentioned in your column mappings.

Look at the columns fields section here: MSDN: GridView Class[^]
