RadPanelBar and SingleExpandedItem vs. FullExpandedItem

I'm trying to set up a panel bar that has the size restrictions of FullExpandedItem, but the behavior for child items of SingleExpandedItem (only one item within a group expanded at a time)

I can come really close by using FullExpandedItem, and using OnClientItemClicking where the function collpapses all the peers of of the item being clicked (if level isn't 0) and it works perfectly....unless you click on the expandhandle.

In that case, the OnClientItemClicking function is never called.

How can I either get a chance to handle the click when the expandhandle is called, or implement this whole thing a different way?

Ajaxify imgbutton in rad grid

I am using 2 RadButtons to search for a (Host or Victim) student then load 2 Radgrids via ajax. 

I am pre populating the search criteria txtFirstName with "Cor" and txtLastName with "A". 

This returns 5 rows from my DB. 

When the Radgrids bind the ajax fires correctly and I can compare the 2 Students below.

In the Other radgrids that hold additional information. 

If I change my search criteria to something else that will return more rows to the RadGrid.

The ajax is only firing for the first 5 rows. 

If I swap out my 2 search RadButtons with regular ASP:Buttons and fire a post back to bind the 2 SearchRadGrids then all the rows are able to fire the ajax correctly.



any help is appreciated? Thanks

Embedded ListView question

I'm working a project where there is a ListView embedded within another ListView.
I'm having difficulty performing a databind on the embedded ListView when the user deletes an entry from it. I receive "Object reference not set to an instance of an object" as an error. The entry does get deleted but I'm unable to refresh the ListView to reflect the deleted entry. Thanks very much for any assistance!

Code:

Protected Sub lvMissionSubTasks_ItemDeleting(sender As Object, e As Telerik.Web.UI.RadListViewCommandEventArgs) Handles lvMissionSubTasks.ItemDeleting

If TypeOf e.ListViewItem Is RadListViewItem Then

Dim lbl As Label = TryCast(e.ListViewItem.FindControl("lblItemID"), Label)

Dim de As New LaunchChecklist.BUS.Items

de.Delete(

CInt(lbl.Text))

'lvMissionSubTasks.DataBind()

Dim lv As RadListView = DirectCast(e.ListViewItem.FindControl("lvMissionLevel3SubTasks"), RadListView)

lv.DataBind()

End If

End Sub

UseSession bug in latest release

Dear Telerik,

The latest release does not work with UseSession="False". I spent a whole day try to figure out what was wrong until I finally tried with an older version and worked fine.
When using UseSession="False" only a red cross appears even with all the correct handlers. Changing to an older assembly version make the charts appear right away.

The version that it works for sure: 2011.3.1115.35
Latest release that doesnt work: 2012.1.215.35

Please let me know if you can fix this or provide a workaround as I would like to use the latest version.

Thanks,
David

Expand/Collapse problem after DataBind in AJAX method

Hello all,

I have a problem with RadTreeList when use DataBind in AJAX method.
This is ASPX

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnSearch">

<UpdatedControls> <telerik:AjaxUpdatedControl ControlID="rtlSearchResult" LoadingPanelID="RadAjaxLoadingPanel1"></telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<asp:Button ID="btnSearch" OnClick="btnSearchClick" runat="server" />

<telerik:RadTreeList runat="server" ID="rtlSearchResult" EnableNoRecordsTemplate="true"

AllowPaging="false" PageSize="5" DataKeyNames="_ID" ParentDataKeyNames="_ID_FOLDER"

Height="250" AllowLoadOnDemand="false" OnItemCommand="rtlSearchResult_ItemCommand"

AutoGenerateColumns="false" Visible="true">

<Columns>

<telerik:TreeListBoundColumn DataField="_ID" UniqueName="_ID" HeaderText="ID"></telerik:TreeListBoundColumn>

<telerik:TreeListBoundColumn DataField="_NAME" UniqueName="_NAME" HeaderText="NAME"></telerik:TreeListBoundColumn>

</Columns>

</telerik:RadTreeList>

CodeBehind

public List<common.DOCUMENT_OBJECT_MAP> list;

protected void Page_Load(object sender, EventArgs e)

{

list = new List<common.DOCUMENT_OBJECT_MAP>();

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 1, NAME = "Obj1" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 11, ID_FOLDER = 1, NAME = "Obj11" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 12, ID_FOLDER = 1, NAME = "Obj12" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 13, ID_FOLDER = 1, NAME = "Obj13" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 14, ID_FOLDER = 13, NAME = "Obj14" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 15, ID_FOLDER = 13, NAME = "Obj15" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 16, ID_FOLDER = 14, NAME = "Obj16" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 17, ID_FOLDER = 14, NAME = "Obj17" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 18, ID_FOLDER = 14, NAME = "Obj18" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 2, NAME = "Obj2" });

list.Add(new common.DOCUMENT_OBJECT_MAP() { ID = 3, NAME = "Obj33" });

if (!IsPostBack)

{

rtlSearchResult.DataSource = list;

rtlSearchResult.DataBind();

}

protected void btnSearchClick(object sender, EventArgs e)

{

rtlSearchResult.DataSource = list;

rtlSearchResult.DataBind();

}

protected void rtlSearchResult_ItemCommand(object sender, TreeListCommandEventArgs e)

{

if (e.CommandName == RadTreeList.ExpandCollapseCommandName)

{

rtlSearchResult.DataSource = list;

rtlSearchResult.DataBind();

}

When is no postback TreeList good work, exand and collapse nodes, but when I click to btnSearch I can't expand/collapse any node. Anybody could help me? Where is a bug?
