OnSelectedIndexChanged for editin inplace Grid drop down list

[Jason]

I have a nice grid working, and in place add,edit and delete working great.

However I am now trying to get a drop down list to trigger the "OnSelectedIndexChanged" event so I can obtain the cost and sell price of the part and place it in the appropriate fields.

<Columns>
                                                                    <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn"
                                                                        CancelImageUrl="~/Images/cancel_16x16.png" EditImageUrl="~/Images/edit_16x16.png"
                                                                        InsertImageUrl="~/Images/update_16x16.png" UpdateImageUrl="~/Images/update_16x16.png"
                                                                        HeaderStyle-Width="50px">
                                                                        <ItemStyle CssClass="MyImageButton" />
                                                                    </telerik:GridEditCommandColumn>
                                                                    <telerik:GridDropDownColumn DataField="PartId" DataSourceID="qry_Parts" HeaderText="Part"
                                                                        ListTextField="Description" ListValueField="PartId" UniqueName="EditPartId" ColumnEditorID="GridDropDownColumnEditorParts"
                                                                        EnableEmptyListItem="False" HeaderStyle-Width="320px">
                                                                    </telerik:GridDropDownColumn>

Neither the GridBouncColumn or the referering ColumnEditor allow this event.

How can I achive this?

Thanks in advance.

Hello Jason,

Try setting DropDownControlType as RadComboBox and attach the event as shown below.
C#:

protected void grid_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name=="")
  {
    GridEditableItem item = (GridEditableItem)e.Item;
    RadComboBox combo = (RadComboBox)item["EditPartId"].Controls[0];
    combo.AutoPostBack = true;
    combo.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(combo_SelectedIndexChanged);
  }
}
 void combo_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
}

Do you have that solution in VB.

Thanks

[Jason]

In VB :

combo.SelectedIndexChanged = New RadComboBoxSelectedIndexChangedEventHandler(combo_SelectedIndexChanged)

does not work as "SelectedIndexChanged" is not available from list. "OnClientSelectedIndexChanged" is though.

Pls help.

Thanks.

Hello Jason,

Here is the code in VB.
VB:

Protected Sub grid_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode AndAlso e.Item.OwnerTableView.Name = "" Then
        Dim item As GridEditableItem = DirectCast(e.Item, GridEditableItem)
        Dim combo As RadComboBox = DirectCast(item("EditPartId").Controls(0), RadComboBox)
        combo.AutoPostBack = True
        combo.SelectedIndexChanged += New RadComboBoxSelectedIndexChangedEventHandler(combo_SelectedIndexChanged)
    End If
End Sub
Private Sub combo_SelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs)
End Sub

Shinu,

Thanks however I believe your conversion is not total correct. I can get this to compile ok, but when I run it , all get is a postback but nothing happens, it doesn't run the "combo_SelectedIndexChanged".

Protected Sub RadGridQuoteItemParts_ItemDataBound(ByVal source As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

        If e.Item.IsInEditMode And e.Item.OwnerTableView.Name = "" Then
            Dim item As GridEditableItem = DirectCast(e.Item, GridEditableItem)
            Dim combo As RadComboBox = DirectCast(item("EditPartId").Controls(0), RadComboBox)

            combo.AutoPostBack = True
            AddHandler combo.Load, AddressOf combo_SelectedIndexChanged

            'MsgBox(combo.SelectedValue & "handler added")
        End If

    End Sub

    Private Sub combo_SelectedIndexChanged(ByVal source As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs)

        MsgBox("selected")

    End Sub

Hi Jason,

Try wiring the event in RadGridQuoteItemParts_ ItemCreated event instead of in the ItemDataBound event.

[Jason]

Protected Sub RadGridQuoteItemLabour_ItemCreated(ByVal source As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

        If e.Item.IsInEditMode And e.Item.OwnerTableView.Name = "" Then
            Dim item As GridEditableItem = DirectCast(e.Item, GridEditableItem)
            Dim combo As RadComboBox = DirectCast(item("EditLabourRateId").Controls(0), RadComboBox)

            combo.AutoPostBack = True
            AddHandler combo.SelectedIndexChanged, AddressOf EditLabourRateId_SelectedIndexChanged

        End If

    End Sub

    Private Sub EditLabourRateId_SelectedIndexChanged(ByVal source As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs)

        Dim intLabourRateIdToLookup As Integer
        Dim strLabourRatePrices As String
        Dim arrLabourRatePrices() As String
        Dim combo As RadComboBox = DirectCast(source, RadComboBox)
        Dim editItem As GridDataItem = DirectCast(combo.NamingContainer, GridDataItem)
        Dim txtEditGridLabourCostRatePerHour As RadNumericTextBox = DirectCast(editItem("EditGridLabourCostRatePerHour").Controls(0), RadNumericTextBox)
        Dim txtEditGridLabourSellRatePerHour As RadNumericTextBox = DirectCast(editItem("EditGridLabourSellRatePerHour").Controls(0), RadNumericTextBox)
        Dim txtEditGridLabourGSTPercentageToApply As RadNumericTextBox = DirectCast(editItem("EditGridLabourGSTPercentageToApply").Controls(0), RadNumericTextBox)

        intLabourRateIdToLookup = e.Value
        'Get Cost and Sell prices
        strLabourRatePrices = returnCostSellPriceForSelectedLabour(intLabourRateIdToLookup)
        arrLabourRatePrices = strLabourRatePrices.Split(";")

        'Update Values
        txtEditGridLabourCostRatePerHour.Text = arrLabourRatePrices(0)
        txtEditGridLabourSellRatePerHour.Text = arrLabourRatePrices(1)
        txtEditGridLabourGSTPercentageToApply.Text = arrLabourRatePrices(2)

    End Sub
