[Solved] Only first item reacts to grid_ItemCommand

[Soren Michelsen]

Hello,

I need to modify a server control from within my grid's ItemCommand event handler. The example below is simplified as much as I can.

Below, I  have an asp:label control inside a NestedItemView in my grid. The label's text property is set in my markup code.

When i expand the row (making the nested view visible), I want to modify the label.text property.

With the code below, when I expand the FIRST row in my grid, the label's text property is modified as it shoud. When I expand other rows, their labels' text properties are not modified.

I know this is a dumb example, but my real-world problem is too muddy to explain here. :-)

Protected Sub radGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles radGrid1.ItemCommand

        Dim nv As GridNestedViewItem = radGrid1.MasterTableView.GetItems(GridItemType.NestedView)(0)

        Dim tmpLabel As Label = CType(nv.Controls(1).Controls(0).FindControl("lblTest"), Label)

        tmpLabel.Text += "_bob"


    End Sub

Any help appreciated.

Hi Jeppe,

Try out the following code snippet to achieve the desired scenario.

VB:

    Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs)
        If e.CommandName = "ExpandCollapse" Then
            Dim currentItem As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim nv As GridNestedViewItem = DirectCast(currentItem.ChildItem, GridNestedViewItem)
            Dim tmpLabel As Label = DirectCast(nv.FindControl("lblTest"), Label)
            tmpLabel.Text += "_bob"
        End If
    End Sub

Regards

Shinu,

Close, but no cigar :-)

Here is my completed code, which calls an instance of a utility class that I made.
This instance returns a webChartViewer, that I then place in the nested view.

If e.CommandName = "ExpandCollapse" Then

            Dim currentItem As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim nv As GridNestedViewItem = DirectCast(currentItem.ChildItem, GridNestedViewItem)
            Dim tmpLabel As Label = DirectCast(nv.FindControl("lblTest"), Label)

            Dim myChartViewer As ChartDirector.WebChartViewer
            myChartViewer = DirectCast(nv.FindControl("WebChartViewer1"), ChartDirector.WebChartViewer)

            Dim wd As <...custom util object ...>
            wd.GetChartWeb(myChartViewer, "MyChartTitle", tmpLabel.Text)
            'getChartWeb parameters
            '1: ChartDirector.WebChartViewer instance
            '2: TitleText for the chart
            '3: ID for records in database to be charted

        End If

Now what happens, is that the "last clicked" item displays my graph, but not the previously clicked items.
To see how it now (not) works, go here: http://www.stmtest.net/grid.wmv

I need all expanded rows to display the chart.
