I'm losing my file listing on the 4th click of Button1. Any thoughts?? Thanks
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
FileExplorer1.RootFolder = "C:\Steve\ProgramFiles\WebSite2\RPTs"
End Sub
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim PathMapping As New EO.Web.PathMapping
FileExplorer1.PathMappings.Clear()
If FileExplorer1.Visible Then
Button1.Text = "show"
FileExplorer1.Visible = False
Else
Button1.Text = "hide"
FileExplorer1.Visible = True
FileExplorer1.RootFolder = "~/RPTs"
PathMapping.Path = "C:\Steve\ProgramFiles\WebSite2\RPTs"
PathMapping.DisplayName = "RPTs"
PathMapping.Url = "http://localhost/WebSite2/RPTs"
FileExplorer1.PathMappings.Add(PathMapping)
End If
End Sub

Hi,
There was a bug related to FileExplorer and post back. It has been fixed in the latest version (.34 build). So please try with that version first.
If you still have problem with the latest build, please try to isolate the problem into a test project. We will be happy take a look as soon as we have that.
Thanks!

Thank you for the quick response. I installed (.34 build).
1. This works: .34 build corrected the post back issue
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
2. I'm required to programmatically hide the FileExplorer. On the 4th click of Button1 the file listing is lost.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim PathMapping As New EO.Web.PathMapping
FileExplorer1.PathMappings.Clear()
If FileExplorer1.Visible Then
Button1.Text = "show"
PlaceHolder1.Visible = False
Else
Button1.Text = "hide"
PlaceHolder1.Visible = True
FileExplorer1.RootFolder = "~/RPTs"
PathMapping.Path = "C:\Steve\ProgramFiles\WebSite2\RPTs"
PathMapping.DisplayName = "RPTs"
PathMapping.Url = "http://localhost/WebSite2/RPTs"
FileExplorer1.PathMappings.Add(PathMapping)
End If
End Sub
3. I removed the PlaceHolder1, same condition prevails.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim PathMapping As New EO.Web.PathMapping
FileExplorer1.PathMappings.Clear()
If FileExplorer1.Visible Then
Button1.Text = "show"
FileExplorer1.Visible = False
Else
Button1.Text = "hide"
FileExplorer1.Visible = True
FileExplorer1.RootFolder = "~/RPTs"
PathMapping.Path = "C:\Steve\ProgramFiles\WebSite2\RPTs"
PathMapping.DisplayName = "RPTs"
PathMapping.Url = "http://localhost/WebSite2/RPTs"
FileExplorer1.PathMappings.Add(PathMapping)
End If
End Sub
Any thoughts? Thanks

Hi,
We have received the test project you sent to us. The problem is a known limitation of the Grid control. The Grid control will lose its data if you set its Visible to false (in your case it’s the FileExplorer, who contains the Grid is set to false).
The easiest way to get around this problem is to put the FileExplorer inside a DIV, then instead of setting the FileExplorer's Visible to false, you would add "display:none" to the DIV's style. That way everything is still rendered to the client but is not visible. In the mean time, we will also see if we can add something such as a "Refresh" on the FileExplorer control to permanently solve the problem.
Thanks!
