Hi,
when I try to perform filter operation in a button event handler the FireCommandEvent method causes an exception.
protected void Filter_Click(object sender, EventArgs e)
{
RadGrid grd = grid;
grid.MasterTableView.FilterExpression = "([Capture] LIKE 'Kind%')";
GridColumn column = grid.MasterTableView.GetColumnSafe("Capture");
column.CurrentFilterFunction = GridKnownFunction.Contains;
column.CurrentFilterValue = "Kind";
grd.EnableLinqExpressions = false;
GridDataItem item = (grid.MasterTableView.GetItems(GridItemType.Item)[2] as GridDataItem);
item.FireCommandEvent("Filter", new System.Web.UI.Pair("Kind", "Capture"));
grid.Rebind();
}
Here is the exception:
An exception of type 'System.NullReferenceException' occurred in Telerik.Web.UI.dll but was not handled in user code
at Telerik.Web.UI.GridColumn.RefreshCurrentFilterValue(GridFilteringItem filteringItem, String functionName)

How can I get it solved?
Thanks in advance.
