DataView.RowFilter doesn't work for a DataTable from a DataSet ?

Question

0.00/5 (No votes)

See more:

I tested DataView.RowFilter and it works OK when the DataView is obtained from a single DataTable (created by DataTable constructor or filled by an adapter). However it doesn't work for a DataTable obtained from a DataSet (DataSet.Tables[index/TableName]). Could you please tell me how to make it work?

Or if possible, please give me another way to filter rows in a DataTable which is as an element of a DataSet???

Thank you!

Hi,
You can take an array of DataRow and use select method from the DataTable.
The code is explained below:

suppose you have a DataTable and let us say you have a column Age, on which you want apply filter,

dt is your DataTable.

DataRows[] drArrRow=dt.Select("Age =" + txtFilter.Text);

lets take another DataTable dtFilter and lets clone it from the dt DataTable

DataTable dtFilter = dt.Clone();

foreach (DataRow d in drArrRow)
{
dtFilter .ImportRow(d);
}
dataGridView1.DataSource = dtFilter;
//Re-Bind your DataGridView for the filtered result.

you are done with your filtered result.

Solution 2

Check this
DataSet ds=getDataSet();
DataView dv = ds.Tables[0].DefaultView;
dv.RowFilter = "ID=12";
DataTable dt = dv.ToTable();

Of course, that's what I did, I also tried DataSet.DefaultViewManager.DataViewSettings["tableName"].RowFilter = "..." and of course this is likely the same to your solution, can't understand why it doesn't work, except the DataGridView's DataSource is a DataTable, a BindingSource, but in my case, it is a DataSet (and use DataMember to specify what table it's bound to). Thanks!
