Answer 1

Try this code:

private void txtSearch_TextChanged(object sender, EventArgs e)
{
    StringBuilder sb = new StringBuilder();

    foreach (DataColumn column in dv.Table.Columns)
    {
        sb.AppendFormat("{0} Like '%{1}%' OR ", column.ColumnName, txtSearch.Text);
    }

    sb.Remove(sb.Length - 3, 3);
    dv.RowFilter = sb.ToString();
    dgClientMaster.DataSource = dv;
}

Answer 2

You'll need to specify the columns you want to search, and separate with an OR clause, like this:

dv.RowFilter = "ClientName Like '%" + txtSearch.Text + "%' OR ClientNickName Like '%" + txtSearch.Text + "%'"; 

Also, you'll need to escape single quotes, or you will get a broken query or SQL injection issues.

You can try

dv.RowFilter = "Column1 + Column2 + Column3" + " Like '%" + txtSearch.Text + "%'";
