Triggering events of series of dynamic sliders

Hi, I am using a database query to setup a series of dynamic sliders within a panel. In the PreRender, the following code successfully generates the sliders:

For Each LocRec In LocRecs

Dim LocationSlider As New RadSlider()

Dim LocationLabel As New Literal

LocationLabel.Text = "<br />" & LocRec.LocationName & "<br />"

LocationSlider.ID = "LocationSlider" & CStr(LocRec.LocationID)

LocationSlider.Width = 300

LocationSlider.AutoPostBack = True

LocationSlider.MinimumValue = 0

LocationSlider.MaximumValue = 1000

LocationSlider.OnClientSlide = "OnClientSlide"

LocationSlider.OnClientValueChanging = "OnClientValueChanging"

LocationSlider.AnimationDuration = 400

AddHandler LocationSlider.ValueChanged, AddressOf LocationSlider_ValueChanged

Panel1.Controls.Add(LocationLabel)

Panel1.Controls.Add(LocationSlider)

Next

The problem is that the event, LocationSlider_ValueChanged never gets triggered:

Public Sub LocationSlider_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs)

'Write slider settings to the database

'This routine never gets executed

End Sub

Why? How can I capture the valuechanged event?

Thanks.

Using ContextMenu with DropDownExtender

Is there an example on how to use the ContextMenu with a DropDownExtender?

RIght now, I am using the Menu control in this instance, with a Vertical flow, however, I am not getting the look and feel that I want. The top level menu looks different then the child items. I figure if I could use a ContextMenu instead, this might result in a better look.

Could anyone provide a sample or a suggestion?

[Solved] Refresh parent grid when detail grid updates

I have a RadGrid with a master table and a details table in a hierarchy. The master shows totals from the data in the details table.

I can edit a row in the details grid and save it without problems. But the total on the master row is then incorrect. I added code to rebind, which works, but then the details grid won't go out of edit mode.

In ItemCommand I check to see if it is the detail table, then do this:

e.Item.OwnerTableView.ParentItem.OwnerTableView.Rebind()

I also tried that line in the Item_Updated event, with the same result.

So how do you cause the master grid to refresh and get the detail grid to exit edit mode?

Thanks

RadCalendar navigates RadScheduler

Hi there,

We have a RadCalendar and a RadScheduler on a page. We need to change the selectdate for the radscheduler when the user clicks on the navigation controls on the radcalendar. But the RadCalendar does not have a navigationComplete event to trigger the event. How should this be handled?

We tried putting it in the PreRender event but it was causing the Scheduler to get reset when we did:
radscheduler.selecteddate=radcalendar.selecteddate

Thank you !

[Solved] ItemDataBound when using DetailTables

In a RadGrid I have one DetailTable that is populated in the DetailTableDataBind event. In the ItemDataBound I set some attributes which works fine until the expand icon is clicked (see error below).
How do I detect (in the ItemDataBound event) that it is the DetailTable that is being databound?

Grid structure:

<telerik:RadGrid ID="rg" runat="server" AutoGenerateColumns="False">

<MasterTableView DataKeyNames="key">

<Columns>

<telerik:GridBoundColumn DataField="key" HeaderText="key" UniqueName="key" />

<telerik:GridBoundColumn DataField="value" HeaderText="value" UniqueName="value" />

<telerik:GridTemplateColumn UniqueName="SelectColumn" AllowFiltering="false">

<HeaderTemplate><asp:CheckBox runat="server" ID="chkAll" ToolTip="Toggle all" /></HeaderTemplate>

<ItemTemplate><asp:CheckBox runat="server" ID="chkItem" /></ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<DetailTables>

<telerik:GridTableView AutoGenerateColumns="true" Name="details" HierarchyLoadMode="ServerOnDemand" />

</DetailTables>

</MasterTableView>

</telerik:RadGrid>

ItemDataBound

Protected Sub rg_ItemDataBound(ByVal sender As Object,

ByVal e As GridItemEventArgs) _

Handles rg.ItemDataBound

Select Case e.Item.ItemType

Case GridItemType.Header

Dim ghi As GridHeaderItem = CType(e.Item, GridHeaderItem)

Dim chkAll As CheckBox = ghi.FindControl("chkAll")

chkAll.Attributes.Add("onclick", "TogglePending(this);")

Case GridItemType.AlternatingItem, GridItemType.Item

Dim gdi As GridDataItem = CType(e.Item, GridDataItem)

Dim ce As Data.DataRowView = CType(e.Item.DataItem, Data.DataRowView)

Dim chkItem As CheckBox = gdi.FindControl("chkItem")

chkItem.Attributes.Add("onclick", String.Format("chkItem_CheckedChanged(this, '{0}');", e.Item.ItemIndex))

End

Select

End Sub

DetailTableDataBind

Private Sub rg_DetailTableDataBind(ByVal source As Object, ByVal e As GridDetailTableDataBindEventArgs) Handles rg.DetailTableDataBind

Dim gdi As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)

e.DetailTableView.DataSource = getDetails(gdi("key").Text)

End Sub
