I have a stiuation where becuase of how I load the page I need to stick in a fillGrid as boolean = false at the top of the load page to keep the NeedDataSource from firing. I then turn it to true when it can fire and rebind the grid. Everything works great up until I need to use the insert of the radgrid and then it bombs out.

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

If Not IsPostBack Then

Dim rspId As String = Request.QueryString("RSP")

If rspId = String.Empty Then

'Send to another page

Else

Dim userlogon As String = Split(Current.User.Identity.Name, "\")(1)

HFUserId.Value = GetPersId(userlogon)

HFRecruitId.Value = rspId

LoadRSP(rspId)

fillGridNotes = True

End If

End Sub

Protected Sub myRadNotes_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles myRadNotes.NeedDataSource

'Load the Notes Grid

If fillGridNotes = True Then

sql = "Select intRspNotesId, CONVERT(varchar(10), dtRSPNotesDateEntered, 111) dtNotes, strRSPNotesDesc, mn.strFullname + ' ' + ISNULL(' ' + strRank, '') LoggedBy from tblRSPNotes n LEFT JOIN MNNGPersonnel..tblMNNatPersonnel mn on " _

& "mn.intPersonnelId = n.intLoggedBy where intRSPID in (Select intRSpId from tblRSp where intRecruitId = " & HFRecruitId.Value & ") Order by dtRSPNotesDateEntered DESC"

myRadNotes.DataSource = getReader(sql)

End If

End Sub

Here is where I am having the problem though, becuase how can I set the boolean statement to true when posting back to do an insert statment on the radgrid.

Protected Sub myRadNotes_ItemCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles myRadNotes.ItemCommand

If (e.CommandName = RadGrid.PerformInsertCommandName) Then

fillGridNotes = True

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim notes As TextBox = DirectCast(editedItem.FindControl("txtNotes"), TextBox)

Dim rspId As Integer = 16533

sql = "Insert tblRSPNotes (intRSPId, dtRSpNotesDateEntered, strRSPNotesDesc, intLoggedBy) VALUES (" & rspId & ", '" & Date.Now & "', '" & sanitizeString(notes.Text) & "', " & HFUserId.Value & ")"

insertUpdateDelete(sql)

myRadNotes.Rebind()

End If

End Sub

AsyncUpload Handler Exeption

Hi all,
I am using the latest version of async control with a handler to upload user images.

The handler code is inside a try...catch statement:

    protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration                      configuration, string tempFileName)
   {
       SampleAsyncUploadResult result = new SampleAsyncUploadResult();
       result.ImageUri = string.Empty;
       result.ImageID = 0;
        try
        {
             .... process image stream......
        }
       catch (Exception e)
        {
           Logger.Error("Error in IAsyncUploadResult Process.....", e);
           result.ImageUri = string.Empty;
           result.ImageID = 0;
        }
       return result;
    }

However, I never see the above error in my log files... Instead I often see the following error, which is logged on the application error even of global.asax:

ERROR 2011-07-19 19:18:47,994 - Application Error by user: 
Telerik.Web.UI.AsyncUpload.AsyncUploadHandlerExeption: RadAsyncUpload handler is registered succesfully, however, it may not be accessed directly.
   at Telerik.Web.UI.AsyncUpload.RequestData..ctor(HttpContext context)
   at Telerik.Web.UI.AsyncUploadHandler.EnsureSetup()
   at Telerik.Web.UI.AsyncUploadHandler.ProcessRequest(HttpContext context)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Can you please help me troubleshoot this problem....

Thank you for your time,
Panagiotis.

customized file upload popup window

Hi Telerik Team,

We try to find a way to customize the file upload control in the Editor's *.manager. The idea is we want to make two tabs in the file upload window, one is select files from local computer which is the same function as now and we also want to add a new tab for external applications. We will implement the new tab feature by ourselves.

We are struggling to find a solution to add two tabs and implement our customized feature in file upload control. Could you please help us out ?

The interface should look like what we see in the attachment.

Thanks in advance!

Must call clearSelection before clearItems() in latest Q1 '14 release

I think a bug might have cropped up into the latest Telerik release (Q1 '14, April SP release). Typically, when clearing and adding items to a combo box client side, script like this has worked:

var combo = $find("MyComboList")
combo.trackChanges();
combo.clearItems();
// code to add items
combo.commitChanges();

However, with the current release, the above code will leave the previously selected item in the combo box as well. In order to remove it, you have to manually clear it, so the above code now becomes this:

var combo = $find("MyComboList")
combo.trackChanges();
combo.clearSelection(); // ensures that the current selected item will be removed as well
combo.clearItems();
// code to add items
combo.commitChanges();

This seems like a bug to me. Can someone from Telerik confirm?

Thanks,

Mike Oliver
