Adding rows when GridView is filtered.

[Thomas Van den Bossche]

Dear Sir/Madam,

Is it possible to add rows when a filter is applied to the GridView?

1. I've added a filter programmatically

FilterExpression filterDriver = new FilterExpression();
filterDriver.Predicates.Add(
             FilterExpression.BinaryOperation.AND,
             GridKnownFunction.Contains,
             GridFilterCellElement.ParameterName );

filterDriver.Parameters.Add( GridFilterCellElement.ParameterName, varFilter );
gridAssigned.Columns[ COLUMN_DRIVER ].Filter = filterDriver;

2. While this filter is active, I want to add a new row programmatically.

GridViewDataRowInfo newRow = gridAssigned.Rows.NewRow();
[...]
gridAssigned.Rows.Add( newRow );

But this doesn't work. I also added

gridAssigned.MasterGridViewTemplate.Update( GridUINotifyAction.RowsChanged );

but without success.

Thanks in advance!

Hi Thomas Van den Bossche,

You can add row/rows to RadGridView when a filter is applied. Newly added rows will be visible only when its data fill the filter criteria. We found some problems with NewRow() method when used in this scenario. The fix will be available for next our release. Currently you can use Add(params object[] values) in your situation:

this.radGridView1.Rows.Add("20", 30, "40");
this.radGridView1.MasterGridViewTemplate.Update(GridUINotifyAction.RowsChanged);

All the best,
