I have a pretty simple scenario using manual data operations with rad list view.  I insert an item into my collection in the ItemInserting event, the listview shows the new item but the insertitemtemplate is still showing.  Is my setup wrong?  Do I have to manually hide the thing?

turns out if you change

Protected Sub rlv_ItemInserting(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadListViewCommandEventArgs) Handles rlv.ItemInserting
        Dim ComboBox As Telerik.Web.UI.RadComboBox = e.ListViewItem.FindControl("RadComboBox1")
  
        If Not String.IsNullOrWhiteSpace(ComboBox.SelectedValue) Then
            Dim UserID As Integer = ComboBox.SelectedValue
            Dim UserName As String = ComboBox.Text
  
            Me.Users.Add(New UserInfo(UserID, UserName))
        Else
            e.Canceled = True
        End If
  
    End Sub

to

Protected Sub rlv_ItemInserting(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadListViewCommandEventArgs) Handles rlv.ItemInserting
        Dim ComboBox As Telerik.Web.UI.RadComboBox = e.ListViewItem.FindControl("RadComboBox1")
  
        If Not String.IsNullOrWhiteSpace(ComboBox.SelectedValue) Then
            Dim UserID As Integer = ComboBox.SelectedValue
            Dim UserName As String = ComboBox.Text
  
            Me.Users.Add(New UserInfo(UserID, UserName))
            rlvSurveyAdministrators.InsertItemPosition = RadListViewInsertItemPosition.None
        Else
            e.Canceled = True
        End If
  
    End Sub

this problem goes away.  Not sure why

I have this same problem.  The solution that you presented works for like a clearing procedure where you reset everything, otherwise it creates some odd things.

This seems like a very simple thing and maybe I am missing something, but I am looking for the opposite of this command:
RadListView1.ShowInsertItem()


Any ideas?  I have to be just overlooking something here...

thanks,

Coty

Hello Coty,

Add the following code snippet in to ItemCommand event of ListView to hid ethe insert form.

C#:
protected void RadListView1_ItemCommand(object sender, Telerik.Web.UI.RadListViewCommandEventArgs e)
   {
       if ((e.CommandName == RadListView.PerformInsertCommandName) || (e.CommandName == RadListView.CancelCommandName))
       {
           RadListView1.InsertItemPosition = RadListViewInsertItemPosition.None;
        }
   }

Thanks,
Princy.
