Questions on UI for ASP.NET AJAX Forum

Hello, I am trying to create a way for the user to view a pdf, xlsx, jpg, gif, etc., from a link button within my Detail table in a radgrid. I am able to accomplish this for a pdf, but not the image files or Excel files.

One of the main issues is that the file types stored within the SQL table field can be any of those above types. My question is how can I write the vb.net code to display any type of file from the same RadGrid column; as the Details Table can have numerous records of different file types.

Here's what I have --

01.<DetailTables>

02. <telerik:GridTableView DataKeyNames="fileID" Name="Attachments" DataSourceID="sdsVenFiles" CommandItemDisplay="Top" Caption="Files Attached to this Vendor Maintenance Request:"

03. NoDetailRecordsText="No files are attached to this Vendor Adjustment request." Width="75%" EditFormSettings-FormCaptionStyle-Font-Bold="true">

04. <ParentTableRelation>

05. <telerik:GridRelationFields DetailKeyField="wfID" MasterKeyField="wfID" />

06. </ParentTableRelation>

07. <CommandItemSettings ShowAddNewRecordButton="false" ShowRefreshButton="true" />

08. <Columns>

09. <telerik:GridBoundColumn SortExpression="fileID" HeaderText="File ID" HeaderButtonType="TextButton" DataField="fileID" Visible="false"></telerik:GridBoundColumn>

10. <telerik:GridBoundColumn SortExpression="wfID" HeaderText="Control #" HeaderButtonType="TextButton" DataField="wfID" Visible="false"></telerik:GridBoundColumn>

11. <telerik:GridTemplateColumn HeaderText="Open File">

12. <ItemTemplate>

13. <asp:LinkButton ID="lnkDownload" runat="server" Text='<%# Eval("fileName")%>' OnClick="viewFile" CommandArgument='<%# Eval("fileID")%>'></asp:LinkButton>

14. </ItemTemplate>

15. </telerik:GridTemplateColumn>

16.

17. <telerik:GridButtonColumn CommandName="Delete" ConfirmText="Delete this file?" HeaderText="Delete" Text="Delete" UniqueName="DeleteColumn1">

18. </telerik:GridButtonColumn>

19. </Columns>

20. </telerik:GridTableView>

21. </DetailTables>

And my vb.net --

01.Protected Sub viewFile(sender As Object, e As EventArgs)

02.

03. Dim id As Integer = Integer.Parse(TryCast(sender, LinkButton).CommandArgument)

04. Dim bytes As Byte()

05. Dim fileName As String, contentType As String

06. Dim constr As String = ConfigurationManager.ConnectionStrings("DbName").ConnectionString

07. Using con As New SqlConnection(constr)

08. Using cmd As New SqlCommand()

09. cmd.CommandText = "SELECT fileID, fileName, fileType, fileData FROM tblVendorFile WHERE fileId=@Id"

10. cmd.Parameters.AddWithValue("@Id", id)

11. cmd.Connection = con

12. con.Open()

13. Using sdr As SqlDataReader = cmd.ExecuteReader()

14. sdr.Read()

15. bytes = DirectCast(sdr("fileData"), Byte())

16. contentType = sdr("fileType").ToString()

17. fileName = sdr("fileName").ToString()

18. End Using

19. con.Close()

20. End Using

21. End Using

22.

23. Response.Clear()

24. Response.Buffer = True

25. Response.Charset = ""

26. Response.Cache.SetCacheability(HttpCacheability.NoCache)

27. Response.ContentType = "application/pdf"

28. Response.BinaryWrite(bytes)

29. Response.Flush()

30. Response.End()

31.

32. End Sub

Thanks for any and all help!

How to show file type icon in Radgrid Grid / Attachment column?

Environment: VS 2008 SP1, ASP.NET AJAX 2009 Q3, WIN XP, IE 7.

Demo I am following is from below link.

http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/gridattachmentcolumn/defaultcs.aspx

Is it possible to show file type along with uploaded file name in RadGrid. Attached are my modified Radgrid (GridAttachmentcolumnDisplay.JPG) and Windows exploreer source folder (GridAttachmentUploadSourceFolder.JPG) for Uploaded Files.

What I mean if Document.rtf has a W icon along with file name in exploreer, I would like to display the file in same display format in Radgrid. Currently in Radgrid it shows C:\Documents and Settings\GC\Test\Document.rtf, no icon for file type. Although by double clicking the uploaded file name, it opens with it's appropriate program type. But showing the file type along with file name will be really helpful to users..

In above Telerik Demo, Sushi.pdf or Customer.xls does not show the windows exploreer like file name icon either.

Thanks

Non-Editable Area not working on Chrome

If you go to this page:

https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

And then go to the HTML tab and pasted this code in:

<div style="border: red 1px solid;" contenteditable="false" unselectable="on">
Non Editable AREA
<div style="border: green 1px solid;" contenteditable="true" unselectable="off">

Editable REGION...

</div>
Non Editable AREA
</div>

Which is from the documentation page:

https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/editable-and-non-editable-areas

If you go back to the design tab, you are unable to type anything in the editable area. This works fine in the legacy edge (non-Chromium).

Also interesting is that you can delete things in the non-editable area.

Add filter builder to kendo grid

I was wondering if it was possible use the filter builder with the kendo grid?

I have been having a number of problems:

1) when i tried to use the Kendo MVC fluent to build my datasource external to the grid nothing ever got output to the page. ei no script was generated

2) when i created the javascript by hand the grid loaded i was able to associate it with the filter and the grid and it appeared i was able to build custom filters, but the filter never bound to the DataSourceRequest request.filter on the controller during a read. This is what is put into the querystring (note i manually put the canimpersonateonly=true)?canImpersonateOnly=True&take=50&skip=0&page=1&pageSize=50&filter%5Blogic%5D=and&filter%5Bfilters%5D%5B0%5D%5Bfield%5D=UvaId&filter%5Bfilters%5D%5B0%5D%5Bvalue%5D=ksa&filter%5Bfilters%5D%5B0%5D%5Boperator%5D=eq

Do you have any samples that use the external filter builder along with the kendo grid in asp.net mvc?

Thanks,

Logan
