Maintaining sort order when transferring between listboxes

I am trying to migrate from a homegrown composite "DualListBox" control. One of the things I spent a lot of time on is making sure that if I moved an item from listbox1 to listbox2, if I moved it back, it moved in the same place. Especially if the source listbox is "sorted." I need to make sure that when I transfer back from one listbox to the original, the sort is maintained. How do I do this?

Edit a radgrid item on new page

In an already existing application I need to make an adjustment. If a user wants to edit a record, the record should be edited on a new page in stead of using a popup. The RadGrid Editmode does not support such function. How can I adjust the control, so I have a link to a new page for editing?

Tooltip with line feed

Hi,

I have created a dynamic tooltip for a radcombobox with checkboxes. As items in the combobox are checked or unchecked I change the tooltip for the combobox to the items that are selected. I have been able to get this to work successfully using the following code.

Private Sub rcbCompany_ItemChecked(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemEventArgs) Handles rcbCompany.ItemChecked

prpSelectedCount = Me.rcbCompany.GetCheckedIndices.Count

Dim strToolTipField = IIf(prpDisplayType = "Name", e.Item.Text, e.Item.Value.ToString)

If e.Item.Checked = True Then

'If an item has been checked, add the company number to the prpSelectedValue list and the company code/name to the prpToolTip list.

prpSelectedValue = prpSelectedValue + "," + e.Item.Attributes("CompanyNumber")

prpToolTip = prpToolTip + strToolTipField

Else

'If no companies are check set prpSelectedValue and the prpToolTip to Nothing,

If prpSelectedCount = 0 Then

prpSelectedValue = ""

prpToolTip = ""

Else

'otherwise remove the unchecked company from the prpSelectedValue property

prpSelectedValue = prpSelectedValue.Replace("," + e.Item.Attributes("CompanyNumber"), "")

prpToolTip = prpToolTip.Replace(";" + strToolTipField, "")

End If

'Remove the extra comma, if any at the beginning of the string

If prpSelectedValue.StartsWith(",") = True Then

prpSelectedValue = prpSelectedValue.Remove(0, 1)

End If

If prpToolTip.StartsWith(";") = True Then

prpToolTip = prpToolTip.Remove(0, 1)

End If

Me.rcbCompany.ToolTip = prpToolTip

rttManagerCompany.TargetControls.Clear()

rttManagerCompany.TargetControls.Add(Me.rcbCompany.ClientID, True)

RaiseEvent OnItemCheckedCompanyHandler(sender, e)

End Sub

Private Sub rttManagerCompany_AjaxUpdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.ToolTipUpdateEventArgs) Handles rttManagerCompany.AjaxUpdate

Dim lblToolTip As New Label()

lblToolTip.Text = prpToolTip

e.UpdatePanel.ContentTemplateContainer.Controls.Add(lblToolTip)

End Sub

My problem becomes when I try to put in a new line in the tooltip text to separate the selected items.
I changed the tooltip expression to

prpToolTip = prpToolTip + "<br/>" + strToolTipField.
After I added the new line character(<br/>) I get the following error.
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

As a test to see if it was my generated tooltip that was causing the problem, I changed the lblToolTip.Text in the rttManagerCompany_AjaxUpdate to "line1 <br/> line2" and I still get the error. If I remove the <br/> I do not get an error and the tooltip displays as line1line2.

Can anyone tell me how to get a new line in the tooltip.

Thank you for your help.
Tracy

Say, If I select row 2, then row 4 and then i hold shift and select row 7 it will select all rows from 2 till 7 instead of 2 and 4 to 7

Error when editing a series from an exception

If I right click on a schedule entry that is an exception from a series, select edit, then select the entire series I get the following when debugging:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

It works fine so long as I edit the series from any item in the series that is not an exception.

Thanks!
