Question

I need to filter a gridview that retreives filtered data from a table. Therefore I bound the gridview to a dataset. Now i can’t seem to find a solution to filter it further.

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
    {
        DataSet ds = new DataSet();
        SqlConnection myCon = new SqlConnection(connectionstring);
        SqlDataAdapter adapter = new SqlDataAdapter(cmd, myCon);
        adapter.Fill(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();
    }
}
protected void Button1_Click(object sender, EventArgs e)
{
//need to insert code here for filtering GridView1 based on TextBox1.Text        
}

Thanks for the help.

Try this:

protected void Button1_Click(object sender, EventArgs e)
{

    DataSet ds = new DataSet();
    SqlConnection myCon = new SqlConnection(connectionstring);
    SqlDataAdapter adapter = new SqlDataAdapter(cmd, myCon);
    adapter.Fill(ds);
    DataView view = new DataView();
    view.Table = ds.Tables[0];
    view.RowFilter = "ColumnName = " + TextBox1.Text.Trim();
    GridView1.DataSource = view;
    GridView1.DataBind();
}

• you have to refactor your code.
