Drag and Drop between Grids

Hi -

I have a page with two RadGrids. Each grid has drag and drop enabled. I use the row-drag capability to re-order items within each grid. The RowDrop event is used on the server side to re-order. It works great. However, I dont want to be able to drag a row from one grid onto the other grid. Is there a way to prevent draging rows from one grid and dropping them on the other on the client? If not, is there a way to determine what the "source" grid was in the RowDrop event on the server. The GridDragDropEventArgs class has a DestinationGrid property in it but no SourceGrid property. Is there a way to determine the source grid so I can just ignore any drops from other grids?

Thanks for your help... Russ

RenderSelectedPageOnly question

Hi, we're using RenderSelectedPageOnly and AutoPostback to load on demand several page views. But now every time we change the selected tab an AJAX request is made (because of the AutoPostback), even though the tab had already been loaded.

We would like to load on demand the selected tab only if it's the first time the user selects that tab. Otherwise the tab change should behave without the AJAX request, just like it would with RenderSelectedPageOnly=false

Is there a way to achieve this behavior?

Best regards,
Santiago.

I am using the Radfilter in my vb.net(2008) project.I am using the RadTreeview as the radcomboboxItem in the datafield editor.I mange to build the control dynamically.But when I add new rows for the filter,previously selected value is set to empty.

Please help on this issue..

Public Overrides Sub InitializeEditor(ByVal container As System.Web.UI.Control)

_combo = New RadComboBox()

_combo.ID = "MyCombo"

_combo.Width = 200

_combo.Height = 180

'For the Treeview

Dim treeItem As New ItemTemplateTreeView(CreateDataSource())

_combo.ItemTemplate = treeItem

Dim item As New RadComboBoxItem()

_combo.Items.Add(item)

_combo.OnClientDropDownOpened = "OnClientDropDownOpenedHandler"

container.Controls.Add(_combo)

End Sub

Public Overrides Function ExtractValues() As System.Collections.ArrayList

Dim list As ArrayList = New ArrayList()

list.Add(DirectCast(_combo.Items(0).FindControl("myTreeview"), RadTreeView).SelectedValue)

Return list

End Function

Public Overrides Sub SetEditorValues(ByVal values As System.Collections.ArrayList)

If Not values Is Nothing And values.Count > 0 Then

If values(0) Is Nothing Then

Return

End If

'Dim item As RadComboBoxItem = _combo.FindItemByValue(values(0).ToString())

Dim item As RadTreeNode = DirectCast(_combo.Items(0).FindControl("myTreeview"), RadTreeView).FindNodeByValue(values(0).ToString())

'If Not item Is Nothing Then

item.Selected = True

_combo.Items(0).Text = item.Text

For Each item As CategoryValueListItem In AnalysItems

Dim dr As DataRow = dataTable.NewRow()

after installing Q1 2011 SP1, VS toolbox is empty!

I'm hoping for some troubleshooting guidance. I just installed RadControls for ASP.NET AJAX Q1 2011 SP1. While there is a Telerik menu, the only menu item in it is "About".

Shouldn't there be something about Upgrade Project...?

Right now we have the Telerik.Web.UI.dll in our BIN directory. Should manually replace that (just copy / paste over it), or is there a "better" way to make sure references and all that are all squared away?

Load User Control After Page Load with Progress Bar

I have a user control that is taking a long time to load (15-20 seconds) mainly because there are many data entry fields and loops to load each field. It is optimized as best I can (one db roundtrip, caching, etc.), but it has nested RadTabStrip controls and other things.

How can I allow a page to load and then, after it has loaded, fire off a server-side (update panel?) call to load my custom user control? Ideally, I want a progress bar that I can interact with as the user control loads.

So, in theory:

1. Page loads.
2. OnLoad, the user control is initialized.
3. A progress bar is displayed in place of the user control.
4. Events fired in the child controls bubble up to the Page to update the progress bar.
5. After the control is loaded, the progress bar is removed and the user control is displayed.

Is this possible using the TelerikRadAjaxManager and Telerik progress bar?

My control events inside panel aren't firing

I have a pretty simple page. I have an Ajax Manager, two Ajax Panels and a very few other controls outside of either panel. In the top Panel, it is just two radio buttons. Depending on which button is clicked, I want the bottom panel to hide or unhide using the panel's .visible property. The default is hidden when the page loads. I have breakpoint in my code (VS2010) for the _CheckedChanged event of both radio buttons and when I click the radio buttons, neither one seems to fire these event.

All I want to do is show or hide the lower panel full of controls.

AjaxManger code:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rbDonationTypeGeneral">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlILMO" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="rbDonationILMO">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlILMO" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Radio-button Panel: (that hides/unhides ILMO panel below)

<telerik:RadAjaxPanel ID="pnlDonationType" runat="server" height="59px"

width="300px">

<asp:RadioButton ID="rbDonationTypeGeneral"

runat="server"

Checked="True"

GroupName="grpDonationType"

Text=" General Donation" />

<br />

<asp:RadioButton ID="rbDonationILMO"

runat="server"

GroupName="grpDonationType"

Text=" In Loving Memory Of..." />

</telerik:RadAjaxPanel>

ILMO Panel: (this is the panel that hides or un-hides depending on which radio button is selected above)

<telerik:RadAjaxPanel ID="pnlILMO" runat="server" height="373px" width="717px" Visible="False">

<br />

<b>In loving memory of:</b>

Event code of the radio buttons:

Protected Sub rbDonationTypeGeneral_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rbDonationTypeGeneral.CheckedChanged

pnlILMO.Visible = False

End Sub

Protected Sub rbDonationILMO_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rbDonationILMO.CheckedChanged

pnlILMO.Visible = True

End Sub

Can someone please tell me what I'm missing or doing wrong. Thanks.
