<ajax:AjaxUpdatedControl ControlID="DdlPoCat" />

</UpdatedControls>

</ajax:AjaxSetting>

</ajax:RadAjaxManager>

<ajax:RadComboBox ID="DdlPoCat" runat="server" Width="240px" AllowCustomText="false" EnableVirtualScrolling="true" EnableLoadOnDemand="True" Text=" " OnClientKeyPressing="clickButton">

<ItemTemplate>

<asp:CheckBox runat="server" ID="chkPoCat" oncheckedchanged="chk_CheckedChangedPoCat" AutoPostBack="True" Text='<%#Eval("ParamDesc")%>' />

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.

Radtreeview inside radcombobox can't change combo value clientside

I'm using a radtreeview inside a combobox, and I'm using the following code for the OnClientNodeClicking event clientside.

The problem is that server side btnSearch_Click event the dropdown always returns the selected value as null.

Any help would be greatly appreciated.

function OnRadTreeViewInComboBoxNodeClicking(sender, args) {

var dropdownId = $('#' + sender.get_id()).closest('.RadComboBoxDropDown').attr('id').replace('_DropDown', '');

var comboBox = $find(dropdownId);

var node = args.get_node()

comboBox.set_text(node.get_text());

comboBox.trackChanges();

comboBox.get_items().getItem(0).set_text(node.get_text());

comboBox.get_items().getItem(0).set_value(node.get_value());

comboBox.commitChanges();

comboBox.hideDropDown();

comboBox.attachDropDown();

$('#btnSearch').click();

}

Add more buttons\controls onto radscheduler appointment

Hi
i'm using the radscheduler in order to create a schedule for ssrs and telerik reports. this will work together with my alerting engine.

currently my page allows the user to select their report and set the report parameters. thereafter they click on the radschedule to select their recurrence and save. This is where i need to add more buttons\ drop downs etc as i require more info on the scheduled report other than just the recurrence. i need to add the extra controls onto the radscheduler appointment popup.

Related list values in combo box

Hi,

We are looking for third party asp.net controls and i am wondering if there is any controls available in telerik which can show related values inside the dropdown/combo box?

We want to show multiple related columns with header inside the combo box so when the user click on the table cell, it will show combo box data in multiple columns format and first columns value is related to second column and second column is related to third.

Country -> City -> Places

Also, is there any combobox control which can show values in tree format with check boxes?

transfer items between TreeViews

Hi there,

I was able to connect to my hierarchical sql data according to demo
http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/databinding/defaultcs.aspx.

Now I need to transfer the items between two TreeViews, similar to the demo below except for the demo is using ListBoxs:
http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/transfer/defaultcs.aspx

But I need to keep the hierarchy information during transfer. Say, if the item belongs to group1 in TreeView1, it will also be shown as group1 item in TreeView2 after transfered to TreeView2.

TreeView2 is blank at first, after finished selecting data from TreeView1, I would like to write everything in TreeView2 to database with hierarchy info.

How could I accomplish that?

Thanks,
Di
