Hi All

Strange one this, if you goto www.weddingdazedirectory.co.uk I'll do my best to explain.

The left hand menu is a user control in a Masterpage

If you make a selection form the left hand menu, the page posts back, but nothing happens.

Now select Advice - Advertorials (I know some in=mages are missing) and make a selection from the left hand menu, you get some results.

Now go back to the home page and make a selection, it now works!

Does anyone have any idea as to what is going on?

The menu is dynamically generated, and I'm using the Item click to redirect to a landing page.

Protected Sub CategoryTree()

'CategoryList

Dim cl As New CoreData

Dim cl_ds As Data.DataTable = cl.CategoryByCounty(0)

With mnuCategory

.Items.Clear()

.DataSource = cl_ds

.DataFieldID = "Category_ID"

.DataFieldParentID = "ParentCategory_ID"

.DataTextField = "Category"

.DataValueField = "Category_ID"

'.DataNavigateUrlField = "Link"

.DataBind()

End With

End Sub

Protected Sub mnuCategory_ItemClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMenuEventArgs) Handles mnuCategory.ItemClick

Dim Category_ID As Int32 = e.Item.Value

Page.Response.Redirect("~/Display/County.aspx?Cat=" & Category_ID)

End Sub

Erik Brink Erik Brink 0 Points 1 Post Save viewstate for inactive tabs over multiple requests

Hi,

In my ASP .NET application I use a tabpanel to let the user open multiple subject from a quickbar, like browser tabs but then inside my application. The content of the subjects is dynamically created server-side. To remain the viewstate of inactive tabpages I need to rebuild the content of the inactive tabpages every request again. When the user opens more subject very request to the server will take longer and longer because of this.

I'm looking for an advanced solution to save the viewstate of inactive tabpages over multiple requests on the active tabpage. When an inactive tabpage becomes active again I want to put the saved viewstate of this tabpage back in the viewstate of the whole page. This can give my application a performance boost when I do not need to rebuild every inactive tabpage on every request to the server.

I have red a lot about the ASP viewstate but I did not found a solution for this yet. Any suggestions how I can accomplish this?

EnableResize Problem

Hi All,

I have set the rad editor to be in "Preview" mode only, however I still want to ability for users to resize the control, so I believed that this should be taken care of using EnableResize="true"

The resize functionality only seems to be enabled when there are multiple modes enabled. e.g. All, Preview + Design etc.

Any ideas on how to fix this?

Cheers,
Jonathan

Upload & save to database help needed

Hi all

This is not a Telerik issue, I just need some pointers.

Using the examples in the help, I have distilled the problem down to the following code, ie no error trapps or validation controls.

I get the error - Value of type '1-dimensional array of Byte' cannot be converted to 'Byte'

On the 'bytes' in the ModelImageAdd function. Why is this, what am I missing?

Protected Sub btnUpload_Click(sender As Object, e As System.EventArgs) Handles btnUpload.Click

BindValidResults()

End Sub

Protected Sub BindValidResults()

If RadUpload1.UploadedFiles.Count > 0 Then

For Each file As UploadedFile In RadUpload1.UploadedFiles

Dim bytes(file.ContentLength - 1) As Byte

file.InputStream.Read(bytes, 0, file.ContentLength)

Dim a As New Model

a.ModelImageAdd(Model_ID, file.GetName(), bytes, Owner_GUID)

Next

End If

End Sub

The function to save the image data looks like this:

Public Function ModelImageAdd(ByVal _Model_ID As String, _ImageName As String, ByVal _ImageData As Byte, ByVal _Owner As Guid) As Boolean

Try

Using sqlConn As New SqlConnection(ConfigurationManager.ConnectionStrings("cnModelDB").ToString)

Using sqlCmd As New SqlCommand()

With sqlCmd

.CommandType = CommandType.StoredProcedure

.CommandText = "ModelImageAdd"

.Connection = sqlConn

.Parameters.Add("@Model_ID", SqlDbType.Int).Value = _Model_ID

.Parameters.Add("@ImageName", SqlDbType.VarChar, 75).Value = _ImageName

.Parameters.Add("@ImageData", SqlDbType.Binary).Value = _ImageData

.Parameters.Add("@Owner", SqlDbType.UniqueIdentifier).Value = _Owner

.Parameters.Add("@ReturnValue", SqlDbType.Int).Direction = ParameterDirection.ReturnValue

.Connection.Open()

.ExecuteScalar()

End With

If sqlCmd.Parameters("@ReturnValue").Value = 0 Then

ModelImageAdd = 1

Else

ModelImageAdd = sqlCmd.Parameters("@ReturnValue").Value

End If

End Using

Catch ex As Exception

ErrorLog.Log(String.Format("Model:ModelAdd(): {0}", ex.Message))

Return False

End Try

End Function

Get Controls in RadGrid's Edit ItemTemplate in Jquery

I have used textbox,label in all GridTemplateColumn's EditItemTemplate. I am unable to get the id of those controls when trying it in jquery.
I tried this method too.

var grid = $find("<%=Grid1.ClientID %>");

var masterTable = grid.get_masterTableView();

var row = masterTable.get_dataItems();

var button = row.findElement("controlname"

);



But I couldn't get the ID. 



If the Grid is in ICGRadAjaxManager's updated control, will the above code work?



Thanks in advance



Vijay.

raddatepicker

I find that in the raddatepicker if you manually type in the date and try to access what is in the object I get 01/01/0001 instead of what was typed in. Is there some setting to set to manual typing is allowed?

Have ListView datapaging maintain its page state when backbutton is used

The scenario is that a user may be on page 4, clicks a link, decides it is the wrong link, then hits the backbutton. The sorted list and page should be maintained. I've tried enabling viewstate, and even storing the page index into the session and having it load on prerender (if not null). What is happening is that when I hit the back button, I get an error stating that the page has expired. What is the normal practice for obtaining this effect and are there any suggestions as to why the page is expiring, preventing my ability to use the back button?
