    in the Editor, click on the Image Manager tool, then click "Upload",
    uncheck "Overwrite if file exists?".
    If I upload three existing files, I get an alert dialog with three times of "A file with a name same as the target already exists!".

    Is there a way to only display one error message "A file with a name same as the target already exists!"?

    I found a post and it seems like the solution doesn't work for me or maybe I miss something.

    I'm using custom control which inherited from RadEditor.
    I tried to add the following code in the custom control, but rfe is always null.

    protected override void EnsureChildControls()
    Telerik.Web.UI.RadFileExplorer rfe =
                if (rfe != null)
                    rfe.ItemCommand += new RadFileExplorerEventHandler(radFileExplorer_ItemCommand);

    private Control FindRadControl(Control parent)
                foreach (Control c in parent.Controls)
                    if (c is Telerik.Web.UI.RadFileExplorer) return c;
                    if (c.Controls.Count > 0)
                        Control sub = FindRadControl(c);
                        if (sub != null) return sub;
                return null;

    protected void radFileExplorer_ItemCommand(object sender, RadFileExplorerEventArgs e)
                switch (e.Command)
                    case "UploadFile":
                        //should I check the existence here?

    Hi Snowolf,

    You can see how to get a reference to the RadUpload control in the Upload dialog of the Image manager in this KB article: Displaying single upload control in the FileBrowser Upload manager.

    Best regards,
