The last thread I saw regarding this is 2011 so I thought I'd revisit. I need to deploy RadScheduler to mobile devices asap. If this functionality is imminent - as in 30-60 days I can probably wait. If it's more than that I will need to use something else (probably the DevExpress product). I'm already a Premium Subscriber and don't want to spend the money with someone else if I don't have to. Can someone give me an update on when this functionality is expected?

Thanks!

Is there any way that move the button on the top instead of having it at the bottom and couldn't find this UploadedFilesRendering. It works fine on AsyncUpload but not in Normal Upload. Is there any way that to fix this issue.

thanks

Access the Containing Node of a Templated Control

Is there a way to reference the containing tree node of a template generated control on the client side, a radcombobox in this case? Without using the Find methods.

Those depend on knowing a particular value rather than the relationship of the node and control. I have a client function that is a handler for the radcombobox OnClientSelectedIndexChanged event, but within that I need to also get a reference to the containing tree node.

Programatically setting RadResizeStopLookup and RadShowStopLookup

Hello all

We're using a fairly oldish release (2010.3.1317.40) on Windows 7 using IE9. I am fairly new to the code base I'm looking at as I'm looking it as an outsider for a sister company to try and sort out some issues.

We're having a problem with performance when resizing a window as a RadGrid with a 1000 rows. It takes a good number of seconds to resize. Searching through the forums I found that setting RadResizeStopLookup="true" RadShowStopLookup="true" in the <div> following the RadGrid definition may ease these problems.

However, our RadGrid is being created in C# and being placed on the page dynamically (not sure of the exact mechanism -- this software generates forms from data in the database) and so there is not aspx file holding the grid. Is there a way of setting these attributes from within C# on the RadGrid object itself?

Thanks in advance for any ideas anyone has.

How Validate Telerik RadUpload - MiMeTypes - Prevent Change Extension

how can i validate telerik radupload for mimeTypes -> mean Prevent Change Extension by users!
in both Client and Server sides!
my radupload is like this :

<telerik:RadUpload ID="RadUpload" runat="server" EnableEmbeddedSkins="False" Skin="BlackByMe" AllowedFileExtensions=".txt" AllowedMimeTypes="text/plain"

ControlObjectsVisibility="ClearButtons" Width="325px">

</telerik:RadUpload>

as you the `AllowedFileExtensions` is txt.
but i can change a zip file extension to txt and upload it.
how can i prevent this act?
there are many methods out there for Telerik RadUpload Validation Such As FileExtension-FileSize-Empty RadUpload.
but what about validating of real MiMeType?

there is a note in telerik web site :
RadUpload does not determine the mime-type using only the file extension. For example if you try to upload a text file that has the extension ".JPG", it is still uploaded with text/plain mime-type.
so why i can still upload a pciture (i zipped it and changed it's extention to txt) with readupload upper?
as you see i set AllowedMimeTypes property.
what is the problem?

i want to show a message to that user who change file extension(clietn and server side for learning)

thanks in advance

Problem with loading tool tip in repeater

I'm trying to fix a site I didn't build and I can't figure out why this data is not binding. It's a tool tip inside of a repeater and the tool tip has a control in it. Here is the code.

<telerik:RadToolTip ID="PaperRevTooltip" runat="server" ManualClose="True" Modal="True"

Position="Center" RelativeTo="BrowserWindow" ShowEvent="FromCode" Skin="Telerik"

Title="Reviewers" Width="400" Height="400">

<asp:Repeater ID="Repeater1" runat="server">

<HeaderTemplate>

<table border="0" cellpadding="0" cellspacing="5">

</HeaderTemplate>

<ItemTemplate>

<UC1:UControl ID="test3" runat="server" PaperID='<%# DataBinder.Eval(Container.DataItem, "PaperID")%>'

ReviewerID='<%# DataBinder.Eval(Container.DataItem, "ReviewerUserID")%>' reviewId='<%# DataBinder.Eval(Container.DataItem, "ReviewOfPaperID")%>' />

</ItemTemplate>

<FooterTemplate>

</table>

</FooterTemplate>

</asp:Repeater>

<asp:SqlDataSource ID="ReviewersSqlDS" runat="server" ConnectionString="<%$ ConnectionStrings:conferencehubConnectionString %>"

SelectCommand="admin_PaperReviewers" SelectCommandType="StoredProcedure">

<SelectParameters>

<asp:Parameter Name="PaperID" Type="Int16" DefaultValue="0" Direction="Input" />

</SelectParameters>

</asp:SqlDataSource>

</telerik:RadToolTip>

Here is the relevant code behind for that page. note the item command comes from a rad grid the tool tip shows, but with nothing but the title

Protected Sub item_command(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles PapersGV.ItemCommand

Dim index As Integer

Dim paperID As String

If e.CommandName = "changeRev" Then

index = e.Item.ItemIndex

paperID = Me.PapersGV.Items(index).GetDataKeyValue("PaperID")

Me.PaperRevTooltip.Title = Me.PapersGV.Items(index).GetDataKeyValue("PaperTitle")

loadPaperReviewersData(paperID)

Me.PaperRevTooltip.visible = True

Me.PaperRevTooltip.Show()

Else

Me.PaperRevTooltip.visible = False

End If

End Sub

Protected Sub loadPaperReviewersData(ByVal paperID As String)

Dim dt As DataTable

Dim connString As String = System.Configuration.ConfigurationManager.ConnectionStrings("conferencehubConnectionString").ToString

Dim myConnection As New Data.SqlClient.SqlConnection(connString)

Dim strSQL As String = "admin_PaperReviewers"

Dim selectCommand As New Data.SqlClient.SqlCommand(strSQL, myConnection)

Dim SQLReader As SqlDataReader

Dim paperIDParam As SqlParameter

Dim values() = {"-1", "-1", "0", paperID, ""}

Try

selectCommand.CommandType = Data.CommandType.StoredProcedure

paperIDParam = New SqlParameter("PaperId", Data.SqlDbType.Int)

paperIDParam.Value = paperID

selectCommand.Parameters.Add(paperIDParam)

myConnection.Open()

SQLReader = selectCommand.ExecuteReader()

dt = New DataTable

dt.Load(SQLReader)

myConnection.Close()

'While dt.Rows.Count < minReviewers

If dt.Rows.Count < maxReviewers Then

dt.Rows.Add(values)

End If

'End While

Me.paperReviewersDT = dt

Me.Repeater1.DataSource = dt

Me.Repeater1.DataBind()

Catch ex As Exception

Response.Write("There has been an error.<br />" & ex.ToString & "<Br />" & strSQL)

Finally

myConnection.Close()

End Try

End Sub

Private Property paperReviewersDT() As DataTable

Get

Return CType(ViewState("allRevs"), DataTable)

End Get

Set(ByVal value As DataTable)

ViewState("allRevs") = value

End Set

End Property

Here is the control uc1

<td>test

<asp:Label ID="output" runat="server"></asp:Label>

<asp:DropDownList ID="RevDropDownList" runat="server" DataSourceID="TrackSqlDS" DataTextField="ReviewerName"

DataValueField="UserID">

</asp:DropDownList>

<asp:CustomValidator ID="revValidator" runat="server" ErrorMessage="*"></asp:CustomValidator>

</td>

<td>

<asp:Button ID="AddButton" runat="server" Text="Add" CommandName="AddReviewer" />

<asp:Button ID="DelButton" runat="server" Text="Delete" CommandName="DeleteReviewer"

Visible="false" />

<asp:Button ID="UpdateButton" runat="server" Text="Update" CommandName="UpdateReviewer"

Visible="false"/>

</td>

<asp:SqlDataSource ID="TrackSqlDS" runat="server" ConnectionString="<%$ ConnectionStrings:conferencehubConnectionString %>"

SelectCommand="admin_AllReviewers" SelectCommandType="StoredProcedure" OnSelecting="TrackItDataSource_Selecting">

<SelectParameters>

<asp:Parameter Name="PaperID" Type="Int32" />

</SelectParameters>

</asp:SqlDataSource>

</tr>

And the control code

Private _ReviewerID As Integer

Private _ReviewID As Integer

Public Property reviewId() As Integer

Get

Return CType(ViewState("reviewId"), Integer)

End Get

Set(ByVal value As Integer)

ViewState("reviewId") = value

End Set

End Property

Public Property PaperID() As Integer

Get

Return CType(ViewState("paperId"), Integer)

End Get

Set(ByVal value As Integer)

ViewState("paperId") = value

End Set

End Property

Public Property ReviewerID() As Integer

Get

Return Me.RevDropDownList.SelectedItem.Value

End Get

Set(ByVal value As Integer)

_ReviewerID = value

End Set

End Property

Public ReadOnly Property ReviewerName() As String

Get

Return Me.RevDropDownList.SelectedItem.Text

End Get

End Property

#Region "SQLDS Events"

Protected Sub TrackItDataSource_Selecting(ByVal sender As Object, ByVal e As SqlDataSourceSelectingEventArgs)

e.Command.Parameters.Item(0).Value = PaperID

End Sub

#End Region

Protected Sub rev_Bound(ByVal sender As Object, ByVal e As System.EventArgs) Handles RevDropDownList.DataBound

Dim defaultItem As New ListItem("- Select Reviewer -", "-1")

RevDropDownList.Items.Insert(0, defaultItem)

output.Text = "test"

If _ReviewerID <> 0 Then

RevDropDownList.Items.FindByValue(_ReviewerID).Selected = True

End If

If isValid() Then

AddButton.Visible = False

UpdateButton.Visible = True

DelButton.Visible = True

End If

End Sub

Public Function isValid() As Boolean

If RevDropDownList.SelectedIndex = 0 Then

revValidator.IsValid = False

Return False

Else

Return True

End If

End Function

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

RevDropDownList.DataBind()

output.Text = "test"

End Sub

Protected Sub AddButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles AddButton.Click

If isValid() Then

ReviewerID = Me.RevDropDownList.SelectedItem.Value

End If

End Sub

I'm kind of lost as to why not even the text "test" shows up when you show the tool tip.
