I'm having problems addressing my fileupload.
My structure looks like this:

<telerik:RadGrid ID="RadGrid1" runat="server">

<MasterTableView>

<NestedViewTemplate>

<asp:Panel ID="Panel1" runat="server">

<telerik:RadTabStrip ID="RadTabStrip1" runat="server">

<Tabs>

<telerik:RadTab runat="server" Text="RadTab1" PageViewID="RadPageView1"></telerik:RadTab>

<telerik:RadTab runat="server" Text="RadTab2" PageViewID="RadPageView2"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server">

<telerik:RadPageView ID="RadPageView1" runat="server">

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView2" runat="server">

<asp:Label ID="Label13" runat="server"

Text='<%# Eval("LokationID") %>'

Visible="false" />

<asp:FormView ID="FormView1" runat="server"

DataSourceID="sdsFile" DataKeyNames="FileID"

DefaultMode="Insert"

oniteminserting="FormView1_ItemInserting">

<InsertItemTemplate>

<table>

<tr>

<td>

<asp:Label ID="Label1" runat="server">

File: (max 1,5GB)

</asp:Label>

</td>

<td>

<asp:FileUpload ID="FileUpload1" runat="server"

Enabled='<%# Bind("FileDocument") %>' />

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label2" runat="server">

Remarks:

</asp:Label>

</td>

<td>

<telerik:RadTextBox ID="RadTextBox1" runat="server"

Text='<%# Bind("FileRemarks") %>'

TextMode="MultiLine">

</telerik:RadTextBox>

</td>

</tr>

<tr>

<td colspan="2">

<asp:ImageButton ID="ibtnInsert" runat="server" CommandName="Insert" />

<asp:ImageButton ID="ibtnAbort" runat="server" onclick="ibtnAbort_Click" />

</td>

</tr>

</table>

</InsertItemTemplate>

</asp:FormView>

<asp:SqlDataSource ID="sdsFile" runat="server"

ConnectionString="<%$ ConnectionStrings:AppendoConnStr03 %>"

SelectCommand="SELECT FileID, LokationID, FileDocument, FileName, FileExtension, FileMIMEType, FileRemarks FROM Files"

InsertCommand=

"INSERT INTO Files(LokationID, FileDocument, FileName, FileExtension, FileMIMEType, FileRemarks) VALUES (@LokationID, @FileDocument, @FileName, @FileExtension, @FileMIMEType, @FileRemarks)">

<InsertParameters>

<asp:ControlParameter ControlID="Label13" PropertyName="Text" Type="Int32" Name="LokationID" />

<asp:Parameter Name="FileDocument" />

<asp:Parameter Name="FileName" />

<asp:Parameter Name="FileExtension" />

<asp:Parameter Name="FileMIMEType" />

<asp:Parameter Name="FileRemarks" />

</InsertParameters>

</asp:SqlDataSource>

</telerik:RadPageView>

</telerik:RadMultiPage>

</asp:Panel>

</NestedViewTemplate>

</MasterTableView>

</telerik:RadGrid>

When I use FileUploads in Formviews outside grids and nestedviews, I use this code:
(which works fine btw :-)

protected void FormView1_ItemInserting(object sender, FormViewInsertEventArgs e)

{

FileUpload fileUpload = (FileUpload)FormView1.FindControl("FileUpload1");

if (fileUpload.HasFile)

{

e.Values["FileName"] = fileUpload.FileName;

e.Values["FileExtension"] = Path.GetExtension(fileUpload.PostedFile.FileName).ToLower();

e.Values["FileMIMEType"] = fileUpload.PostedFile.ContentType;

e.Values["FileDocument"] = fileUpload.FileBytes;

}

else

{

e.Values["FileName"] = null;

e.Values["FileExtension"] = null;

e.Values["FileMIMEType"] = null;

e.Values["FileDocument"] = System.Data.SqlTypes.SqlBinary.Null;

}

But inside the nestedview, it seems like I'm not able to address the correct formview - no matter what I try, I always ends up with no file found in the fileupload and null-values in the DB.

NB. The values from Label3 and RadTextBox1 are stored just fine in the DB.

Any helps would be appriciated :-)

Sure thing, here is an example. Please let me know if you have any questions!

I hope this helps!

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "Insert")

{

GridEditFormInsertItem insItm = e.Item as GridEditFormInsertItem;

FileUpload fileUpload = insItm .FindControl("FileUpload1") as FileUpload;

if (fileUpload.HasFile)

{

}

else

{

e.Canceled = true;

}

Hmm, well I'm able to get a reference to the FormView, and then the FileUpload. I wasn't able to setup my page exactly like yours (I couldn't get it to display properly with the RadMultiPage), but here is how I was able to do so. I also used an ObjectDataSource.

I'm curious as to why you are using a FormView inside of the NestedViewTemplate, instead of specifying a FormTemplate in the EditFormSettings for the RadGrid. Instead of expanding the rows of the RadGrid, the users would have to click an edit link to put the row in EditMode, but I think it would eliminate a lot of the coding hassle you are experiencing.

I hope this helps!

Hi Casey :-)

I tried your suggestion, but now I'm having problems passing values to the SqlDataSource.

I've added this to your suggestion:

if(FileUpload.HasFile)

{

sdsFile.InsertParameters["FileName"].DefaultValue = FileUpload.FileName;

sdsFile.InsertParameters["FileExtension"].DefaultValue = Path.GetExtension(FileUpload.PostedFile.FileName).ToLower();

sdsFile.InsertParameters["FileMIMEType"].DefaultValue = FileUpload.PostedFile.ContentType;

sdsFile.InsertParameters["FileDocument"].DefaultValue = FileUpload.FileBytes;

}

else

{

...

But FileUpload.FileBytes is a byte array and you can only pass strings as defaultvalue.
The file is stored in the DB as Varbinary(MAX).

I've added two screenshots of my solution so far, to show what I'm trying to accomplish :-)
It's partial danish and partial swedish, but it's the structure, you should look at :-D
