How I can search rows in a datatable with a searchstring?

Question

I want to search rows in my DataTable.

I\'ve tried this:

 protected void imggastsuche_Click(object sender, EventArgs e) 
        {

I just made a extension method to the DataTable class for this. It returns a new Datatable containing only the rows you want.

public static DataTable SearchInAllColums(this DataTable table, string keyword, StringComparison comparison)
{
    if(keyword.Equals(""))
    {
        return table;
    }
    DataRow[] filteredRows = table.Rows
           .Cast()
           .Where(r => r.ItemArray.Any(
           c => c.ToString().IndexOf(keyword, comparison) >= 0))
           .ToArray();

    if (filteredRows.Length == 0)
    {
        DataTable dtTemp = table.Clone();
        dtTemp.Clear();
        return dtTemp ;
    }
    else
    {
        return filteredRows.CopyToDataTable();
    }
}

Usage:

DataTable dataTable = getData();
dataTable.SearchInAllColums(Keyword, StringComparison.OrdinalIgnoreCase);
