Change InitialPath not working

[Redmond Rinehart]

I have a RadGrid where I want a user to select a row and on that postback, I want to set the InitialPath of the FileExplorer based on their selection.  For some reason it isn't working.  When I debug, the path is correct and and there are no errors, but the FileExplorer remains empty.  How can I set the InitialPath programmatically?

    Protected Sub rdgSurveys_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rdgSurveys.SelectedIndexChanged
        SetFileExplorerPaths()
    End Sub

    Protected Sub SetFileExplorerPaths()
        If rdgSurveys.SelectedValue > 0 Then
            rfeDocuments.Enabled = True

            Dim surveyPath = "~/bin/Documents/Survey_" + rdgSurveys.SelectedValue.ToString
            Dim paths As String() = {surveyPath}
            rfeDocuments.InitialPath = surveyPath
            rfeDocuments.Configuration.UploadPaths = paths
            rfeDocuments.Configuration.ViewPaths = paths
            rfeDocuments.DataBind()
        Else
            rfeDocuments.Enabled = False
        End If
    End Sub

Hello Redmond,


To set the initial path properly, you need to convert the root relative Url.
e.g.

Dim surveyPath = Page.ResolveUrl("~/bin/Documents/Survey_") + rdgSurveys.SelectedValue.ToString

I hope this helps. If you still experience problems after that, it will be best to open a support ticket and to send us a sample project where this issue could be reproduced - we will check it right away.

Hi,

can you explain me how I can set initial path if I'm using SPContentProvider class? Is there a different approach?

radFileExplorer.Configuration.ViewPaths = new string[] { "/MyRootFolder" };
radFileExplorer.InitialPath = "/MyRootFolder/1. vrstva Řídící dokumenty/Kolektivní smlouva/";

I know that the path is case sensitive so I have checked twice the source path.

Thx your very much

Pavel

Hello Pavel,

The "Value cannot be null." has been fixed and the fix will be included in the Q2 2009 official release.

The value of the InitialPath property must be equal to what you see in the address bar of the file explorer control when you have navigated to the folder you want to be opened initially.

Hi Telerik,
how do I change InitialPath over AjaxRequest?
Thanks for a hint,
Andreas

[Lini]

Hello Andreas,

InitialPath is only taken into account when the file explorer is first loaded and populated with data. If you want to change the folder after that, you can use the explorer.loadFolder(path) client API method. This will make an Ajax request and change the current folder in the file explorer's tree and grid components.
