I have a Dynamic-Data application with a List.aspx main page listing data which can be filtered by country. The country table is used as a DynamicFilter as it is a foreignkey to the main table.

When I choose a state the DynamicFilter_FilterChanged method fires and it filters the main table properly but I'm trying to figure out how I can get the total number of rows that the filtering has produced.

I've looked at previous posts here with no luck.

Any ideas?

You can count when the Gridview on the list.aspx page is selected 

protected void GridDataSource_Selected(object sender, LinqDataSourceStatusEventArgs e)
{
    if (e.TotalRowCount > 0)
    {
        lblCount.Text = e.TotalRowCount.ToString() + ((e.TotalRowCount == 1) ? " item found." : " items found.");
    }
}

  • When does this method fire? I added this code and when I click the Country drop-down list and select a country the GridView gets filtered properly but this method never fires. – DevilDog Dec 11 '12 at 17:51
  • Sorry, wasn't included. This fires on the OnSelected Event on the LinqDataSource (or whatever data source) that populates the Gridview. – Ash Machine Dec 12 '12 at 21:34
  • I guess the Gridview datasource is not being selected because this method "GridDataSource_Selected" is not being fired? – DevilDog Dec 14 '12 at 21:36
  • Do you have OnSelected="GridDataSource_Selected" in your LinqDataSource tage? – Ash Machine Jan 09 '13 at 21:04
