I need to resort, in memory, a DataTable based on a column and direction that are coming from a GridView. The function needs to look like this:
public static DataTable resort(DataTable dt, string colName, string direction)
{
DataTable dtOut = null;
....
}
I need help filling in this function. I think I can use a Select statement but I am not sure how. I can't click on Comments because of this browser but you can show me an in-place or new DataTable solution, either one. For the people showing me pointers, please, I need a coded function similar to the one prototyped.
How about:
// ds.Tables[0].DefaultView.Sort="au_fname DESC";
public static void Resort(ref DataTable dt, string colName, string direction)
{
string sortExpression = string.Format("{0} {1}", colName, direction);
dt.DefaultView.Sort = sortExpression;
}
I assume "direction" is "ASC" or "DESC" and dt contains a column named "colName"
public static DataTable resort(DataTable dt, string colName, string direction)
{
DataTable dtOut = null;
dt.DefaultView.Sort = colName + " " + direction;
dtOut = dt.DefaultView.ToTable();
return dtOut;
}
OR without creating dtOut
public static DataTable resort(DataTable dt, string colName, string direction)
{
dt.DefaultView.Sort = colName + " " + direction;
dt = dt.DefaultView.ToTable();
return dt;
}
