Accessing child controls inside of a GridView inside of a MultiView
I have a fileupload control which is in a itemtemplate field within the GridView:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="Trk_SqlDataSource">
<Columns>
<asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" />
<asp:TemplateField HeaderText="Upload Track">
<ItemTemplate>
<asp:FileUpload ID="FileUpload2" runat="server" />
<asp:Button ID="Button4" runat="server" OnClick="Button4_Click" Text="Upload" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>All of this is inside of View2 of a Multiview on a single page.
I am trying to access the fileupload control when i click Button4 using this code:
protected void Button4_Click(object sender, EventArgs e)
{
string myMusicDirectory = "../media";
string audioFileName = string.Empty;
if (((FileUpload)GridView1.FindControl("FileUpload2")).HasFile)
{
audioFileName = ((FileUpload)GridView1.FindControl("FileUpload2")).FileName;
int filesize = ((FileUpload)GridView1.FindControl("FileUpload2")).PostedFile.ContentLength;
if (filesize > 0)
{
string savedAudioFileName = myMusicDirectory + @"/" + Path.GetFileName(audioFileName);
((FileUpload)GridView1.FindControl("FileUpload2")).SaveAs(Server.MapPath(savedAudioFileName));
}
}
}
and i keep getting the error of:
Error 156 Cannot convert type 'System.Web.UI.Control' to 'FileUpload'
I apologize if this has been discussed earlier I tried searching this site and countless others but I'm stumped here. So how do i go about accessing the child controls in the GridView which is inside of a View within a Multiview?
Thank you in advance.

Use a recursive control search that can drill down all levels of the control hierarchy
See several of my previous posts on this

If it was easy, everybody would be doing it.
