How to get another DataTable from original DataTable?

[nhatvhm]

Here, it is source code

public DataTable SearchField(string strSearch, string strFieldName)
{
DataTable dt = new DataTable();

        foreach (DataRow dr in data.Rows)
        {
            string strT = dr\[strFieldName\].ToString();
            if (stringSearchMP(strSearch, strT) != -1)
            {
                DataRow row = dr;
                dt.ImportRow(row);
            }
        }
        return dt;
    }

I don't know to cause why my function return null. Because, DataGridView.DataSource = dt can't show data. Anyone help me?:confused: Anyway, thanks so much!!!

maybe you need ot clone the table structure from source datatable,like 'dt=data.Clone()',then import rows.

I think you mistake and omit line dt = data.Clone() before foreach(DataRow dr in data.Rows)
