DataView from DataViewManager

[rk]

Hi,

I am using a DataViewManager to display the dataset in a datagrid. Once
the rowfilter is applied, I would like to know the no. of rows returned
so that I can display it on the screen. I would like a way to get the
underlying DataView to get the count but I am unable to find it.

Here is what I am doing:

string filter = "...";
DataViewManager dvm = new DataViewManager (myDataSet);
dvm.DataViewSettings["table"].RowFilter = filter;
this.myDataGrid.SetDataBinding (dvm, "table");


thanks

rk,

Instead of binding to your DataViewManager, I would bind to the DataView
returned by a call to CreateDataView. Then, you can use the view to get the
count of the number of rows when the filter is applied.

Hope this helps.

Nicholas,

Thanks for the suggestion - it worked just fine. But I wanted to use
DataViewManager and I am wondering why there is no way to extract the
underlying DataView if the DataViewManager does create a dataview on
all the underlying tables?

Just wondering.
