RadPageView not showing updated repeater rows on single button click

hello,

i have a web page on which 3 user controls A,B,C are registered.

RadTab controlis used and User controls A and B is added on RadPageView 1 and 2 respectively.

User Control C also exists on the same web page but not on the RadTab.

By default, RadPageView 1 i.e. User Control A is selected.

On User Control B there exists a repeater to which some rows are binded.

On User Control C, there is a link button. When it is clicked, RadPageView 2 i.e. User Control B should be selected

and the repeater rows shud be filtered accordingly. Now, the problem is that when the link button is clicked

the repeater is having the correct number of rows but the RadPageView 2 is showing the correct number of rows

till i click the link button twice.

Please help.

Drag and Drop Re-Order / Row Selection

I have a number of rad grids in my project that go to edit screens on selected index changed, which in turn occurs when a row is clicked with "AllowRowSelect" to true. No problem so far.
Now I have a requirement to allow the user to re-order the rows using the radgrids drag and drop capability. I followed the example and this works fine, too.
The problem occurs when I try to combine the two functions in one grid. The act of clicking to begin the drag process changes the selected index and the redirect to the edit occurs. I would like to be able to click anywhere on the row other than the drag handles and have it go to edit, but if I click the drag handle, allow the drop and re-ordering.
Can I use the same grid to achieve both purposes?

Ajaxloadingpanel stoped when load page with radlistview

Hi,

I've two page aspx: first page is search.aspx, second page is reasult.aspx

into page search.aspx i write this code:

Response.Redirect(

"reasult.aspx?_str1=" & Txtsearch1.Text & "&_str2=" & Txtsearch2.Text)

and then pass the values to the second page result.aspx....Into first page there's a ajaxloadingpanel that appears when I send the data, but the loading is still.

Perhaps because the page has result.aspx in load_page loading data from the database? And so it stops loading.

this code in second page:

Imports System

Imports System.Data

Imports System.Web

Imports System.Data.SqlClient

Imports Telerik.Web.UI

Imports System.IO

Private Loadsearch As New GestoreUtente

Dim list As List(Of PropertyUtente) = Loadsearch.Search(_str1, _str2)

RadListView1.DataSource = list

RadListView1.DataBind()

Public Class GestoreUtente

Public Function Search(ByVal _Str1 As String, ByVal _Str2 As String) As List(Of PropertyUtente)

Dim lista As New List(Of PropertyUtente)

Try

Dim conString = ConfigurationManager.ConnectionStrings("TrycontactString")

Dim strConnString As String = conString.ConnectionString

Using db As New SqlConnection(strConnString)

db.Open()

Using sqlcmd As New SqlCommand("Sp_searching_like", db)

sqlcmd.CommandType = CommandType.StoredProcedure

sqlcmd.Parameters.AddWithValue("@Search", SqlDbType.VarChar).Value = _Str1

sqlcmd.Parameters.AddWithValue("@Searchluogo", SqlDbType.VarChar).Value = _Str2

Using sqldr As SqlDataReader = sqlcmd.ExecuteReader

While sqldr.Read

lista.Add(New PropertyUtente With {.idutente = sqldr.GetSqlInt32(0).Value, _

.utente = sqldr.GetSqlString(1).Value, _

.Desccategoria = sqldr.GetSqlString(2).Value, _

.Desccomune = sqldr.GetSqlString(3).Value, _

.Telefono = sqldr.GetSqlString(4).Value, _

.Cellulare = sqldr.GetSqlString(5).Value, _

.Imageprofile = sqldr.GetSqlString(6).Value, _

.Email = sqldr.GetSqlString(7).Value})

End While

End Using

Catch ex As SqlException

Exit Try

Catch ex As Exception

Exit Try

End Try

Return lista

End Function

End Class

Style by hidden resource/attribute

Is there a way for me to style by a hidden resource/attribute? Every time an event is written I also log which user enters it via a insert parameter that is assigned via page_load so the user never sees this field and its not part of the form. I would assume I need to add it as a resource or attribute and then set the visibility to false and set the value to something if I want to make it work?
