[Solved] Display Network Folder

[Rick]

I am looking for a solution that will allow me to click a button or a hyperlink within a row and open a folder on our network.  The location to be opened is stored in the record source for that grid.

I have tried a couple of things, both of which failed.  Granted, the solution I have are either my own creation or a hybrid of my code and assistance from the forums.


FAILED SOLUTION #1
This column contains a button that opens the folder.  This does work locally, but does not work when published to our web folder.

<telerik:GridButtonColumn FilterControlAltText="Filter Files column" CommandName="ShowFiles"  UniqueName="Files" ButtonType="PushButton" HeaderText="Files" Exportable="False" Text="Display">
</telerik:GridButtonColumn>

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

 

    Dim value As String

 

    If e.CommandName = "ShowFiles" Then

        Dim dataItm As GridDataItem = TryCast(e.Item, GridDataItem)

 
        value = dataItm("Location").Text & "\03 Submitted\"

  

        Process.Start("explorer.exe", value)

  

    End If

 

End Sub

FAILED SOLUTION #2
This does nothing but reload the page. 

<telerik:GridTemplateColumn UniqueName="LinkColumn">
    <ItemTemplate>
        <asp:LinkButton runat="server" ID="LinkButton1" CommandName="ShowFiles"></asp:LinkButton>
    </ItemTemplate>
</telerik:GridTemplateColumn>

Private Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemDataBound

    If TypeOf e.Item Is GridDataItem Then
        Dim item As GridDataItem = TryCast(e.Item, GridDataItem)
        Dim row As DataRow = TryCast(item.DataItem, DataRowView).Row
        Dim linkButton As LinkButton = TryCast(item("Location").FindControl("LinkButton1"), LinkButton)
        linkButton.Text = "Location"
        linkButton.PostBackUrl = "#"
    End If

End Sub

  

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

    Dim value As String

    If e.CommandName = "ShowFiles" Then

        Dim linkButton As LinkButton = TryCast(e.CommandSource, LinkButton)
        Dim dataItm As GridDataItem = TryCast(e.Item, GridDataItem)
        value = dataItm("Location").Text & "\03 Submitted\"

        Process.Start("explorer.exe", value)

    End If

End Sub

FAILED SOLUTION #3

I changed the link format as follows.  This only reloads the page, but again, it works locally.

If e.CommandName = "ShowFiles" Then

    Dim linkButton As LinkButton = TryCast(e.CommandSource, LinkButton)
    Dim dataItm As GridDataItem = TryCast(e.Item, GridDataItem)
    value = dataItm("Location").Text & "\03 Submitted\"

    Process.Start("explorer.exe", "file:///k|/Proposal/2014")

End If

Hi Rick,

Could you please verify if the same approaches for opening the local folder work out of the RadGrid  control?
Generally the mentioned issue is not related to the RadControls but is most probably environment issue as some of the approaches work locally and not when the site is published.
You should revise the environment configurations and the specific folder permissions and isolate the issue on your end.

Thanks for your reply.  We eventually got this working with IE and also Chrome with a plug-in.  Nothing special...  I always test in Chrome and never checked IE to see if that would work.

We may already have permissions configured on the folder to allow this.

<telerik:GridTemplateColumn ColumnGroupName="DLB" UniqueName="Location"  Display="True" HeaderText="Files" >
    <ItemTemplate>
        <a href="<%# Eval("Location")%>" target="_blank">Open folder</a>
    </ItemTemplate>
</telerik:GridTemplateColumn>
