PROJECT DESCRIPTION

I have written a small code to test loding of menu from an object collection (Entity spaces)

RadMenu1.DataFieldID =

"MenID"

 

RadMenu1.DataFieldParentID =

"MenMenIDParent"

 

RadMenu1.DataNavigateUrlField =

"MenNavigateUrl"

 

RadMenu1.DataTextField =

"MenName"

 

 

Dim sp As MenuCollection = New MenuCollection

 

sp.GetMenuForUser(1)

RadMenu1.DataSource = sp

RadMenu1.DataBind()

the code runs but the menu is blank. any suggestion???
I checked my collection it is returning 16 entities/objects.

The application I am building is using .NET theme files to properly apply skins to various elements.  My problem is simple:

In my skin file I have some items as follows:

What I would like to do, is based on the data being bound to the treeview is assign a different SkinID to each node as they are created.

My problem is that the 2 events I have to work with, NodeCreated and NodeDataBound, won't accomplish this.  NodeCreated is too early because I can't determine the type of node being created because the DataItem value of e.Node is null.  NodeDataBound is too late because the node has already been added to the Controls collection and the SkinID cannot be assigned.

How would I go about accomplishing this?

Thanks

 

 

 

I have been unable to get RadControls to work with DotNetNuke 5.0. Has anybody succeeded in using them with DNN 5.0?

Are there any Telerik demos of RadControls, especially RadGrid, showing how to make them work with DotNetNuke 5.0?

All the examples have the insert form showing up at the top of the grid?. Is there a way to make it show at the bottom. My add button is there so it makes more sense to show at the bottom.

In IE8 beta there is one annoying issue when using RadSplitter and async postbacks with RadAjaxPanel. The RadSplitter simply moves downwards a bit when the async postback completes, leaving a gap of empty space above it. This happens at least when the RadSplitter is the parent element in the page, and it occurs regardless of width/height settings.

As quite a few of our users have installed IE8 and are complaining about this issue, could you please check whether it is a bug in IE8 or if RadAjaxPanel adds some content to the page causing the RadSplitter to move? The problem is simple to reproduce using the following code:

Hi,

We have a page with a pair of grids - one containing selected items and one containing items that have not been selected.

We want to allow dragging within the grid of selected items, to allow for reordering, and we want to allow for dragging between the grids to allow items to be selected or unselected.

The complication is that we have a few items that we do not want to be draggable.  They should appear at the top of the grid of selected items, and they should stay there.  The user should not be able to drag them to another locating in the selected items grid, and the user should be able to drag them to the unselected items grid.  In other words, the user should not be able to unselect them or to reorder them.

Any advice as to how accomplish this?  There is an invisible GridBoundColumn in the grid called "Fixed" containing "True" or "False".  I've tried using this in OnItemDataBound to set item.Enabled = false, and the appropriate rows are appearing greyed out in the grid.  But I can still drag the disabled rows.

Any ideas?

Hi,
Thanks for resolving my problem in the past. Here is another one and I spent 3 hours on this & cant figure out. Please help

I am using tooltip as a popup message control. I have two scenarios - one is using tooltip to display text and the other one is using tooltip to display content inside of control(s). In this case, i'll use label as the parameter for popup - see below


Let say I have two buttons and upon click - it will either call ShowPopupMessage(String) or ShowPopupMessage(Label control).

If I click on ShowPopupMessage(String) and then click on ShowPopupMessage(Label) - the 2nd popup does not show the right content. It is still showing ShowPopupMessage(String) content. Any idea? Thanks!

Hi, I'm having problems to export the data of my grid.
My code to export the data:

Protected Sub btExpCsv_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btExpCsv.Click
      
        RadGrid1.ExportSettings.ExportOnlyData = True
        RadGrid1.ExportSettings.IgnorePaging = True
        RadGrid1.ExportSettings.OpenInNewWindow = True
        RadGrid1.MasterTableView.ExportToCSV()
    End Sub

    Protected Sub btExpExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btExpExcel.Click
       
        RadGrid1.ExportSettings.ExportOnlyData = True
        RadGrid1.ExportSettings.IgnorePaging = True
        RadGrid1.ExportSettings.OpenInNewWindow = True
        RadGrid1.MasterTableView.ExportToExcel()

    End Sub

    Protected Sub btExpPdf_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btExpPdf.Click
      
        Dim dataAtual As Date
        dataAtual = System.DateTime.Now
        RadGrid1.ExportSettings.ExportOnlyData = False
        RadGrid1.ExportSettings.IgnorePaging = True
        RadGrid1.ExportSettings.OpenInNewWindow = True
        RadGrid1.ExportSettings.Pdf.AllowCopy = True
        RadGrid1.ExportSettings.Pdf.PaperSize = GridPaperSize.Oficio
        RadGrid1.ExportSettings.Pdf.PageTitle = "Relatório Pontos Analógicos - " & dataAtual
        RadGrid1.MasterTableView.ExportToPdf()

Any help would be very appreciated.

Hi,
  I am using radGrid in ASPNET AJAX Q3 2008.  The enable the scrolling and changed my grid height to 200px, everything looks fine.  But whenever there is a postback on the page, the grid goes back to its original size, then changes back to 200px right away.  Is it a glitch of the grid or I missed something?
