Hide Collapse image when no records using an object to populate detail table

I tried the http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html way of hiding the expand/collapse image but with no success. I don't use the HierarchyLoadMode = ServerBind way of populating the details table - but I don't have a problem populating the details table.

Here is the code for the detail table bind and my attempt to hide the collapse/expand column for parent rows with no detail items:

Private Sub RadGridEvents_DetailTableDataBind(ByVal source As Object, ByVal e As GridDetailTableDataBindEventArgs) Handles RadGridEvents.DetailTableDataBind

Dim dataItem As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)

Select Case e.DetailTableView.Name

Case "EventMerchantList"

Dim EventID As Integer = dataItem.GetDataKeyValue("eventID")

Dim eventML As List(Of Merchant)

eventML = Merchant.GetAllMerchantsByEventID(EventID)

If Not eventML Is Nothing Then

If eventML.Count > 0 Then

e.DetailTableView.DataSource = eventML

End If

End Select

End Sub

Protected Sub RadGridEvents_PreRender(ByVal sender As Object, ByVal e As EventArgs)

HideExpandColumnRecursive(RadGridEvents.MasterTableView)

End Sub

Public Sub HideExpandColumnRecursive(ByVal tableView As GridTableView)

Dim nestedViewItems As GridItem() = tableView.GetItems(GridItemType.NestedView)

For Each nestedViewItem As GridNestedViewItem In nestedViewItems

For Each nestedView As GridTableView In nestedViewItem.NestedTableViews

If nestedView.Items.Count = 0 Then

Dim cell As TableCell = nestedView.ParentItem("ExpandColumn")

cell.Controls(0).Visible = False

nestedViewItem.Visible = False

End If

If nestedView.HasDetailTables Then

HideExpandColumnRecursive(nestedView)

End If

Next

End Sub

It seems like this should be an easy thing to do but I cannot find the answer. Thanks in advance for any help I get with this.

Value Not Returned On Second Selection

Hello,
   We are currently using a RadComboBox with loadOnDemand within our MasterPage.   The SelectedValue of the ComboBox and the SelectedText are properly returned to the SelectedIndexChanged Event when a combobox item is selected from the drop down for the first time but not upon the second selection. To be more clear. If you have 3 ComboboxItems (in our case "projects") : Item 1, Item 2 and Item3. If Item 1 is selected the SelectedIndexChangedEvent works as expected. Both the Text and Value of the event are populated in the event handler as expected, If Item 2 is selected the same expected behavior occurs. If however a user were to RE select Item 1 after previously selecting Item 1 during the same session then ONLY the Text of the event handler is populated in the event value is not populated. To make matters slightly more confusing the SelectedValue of the combo Box is also returning an empty string only on the reselection but appears to be working properly for the initial selection.. I have no idea why everything seems to be working fine for the first iteration of a selection but not the second. Any advice would be sincerely appreciated. Relevant Code Below:

C#

protected void rcbCurrentProject_ItemsRequested(object sender, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)
        {

            var projects = FluxPermissionManager.GetUserProjectAccess(Page.User.Identity.Name).Select(lkj => new { name = lkj.name, testProjectID = lkj.testProjectID });
            rcbCurrentProject.DataSource = projects.ToList();
            rcbCurrentProject.DataBind();

            e.Message = "Displaying All Accessible Projects";
        }

    protected void rcbCurrentProject_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
        {
            try
            {
       //e.Text Is populated Properly.... no issues
       string projectName = e.Text

       //e.Value returns an empty string following the second time selected.
                int val = Int32.Parse(e.Value);

       . . . ...
        }

       }

ASPX

    <telerik:RadComboBox ID="rcbCurrentProject" runat="server" ErrorMessage="None Selected" EnableLoadOnDemand="true"
                                ShowMoreResultsBox="false" AutoPostBack="true" EnableVirtualScrolling="false" OnPreRender="rcbCurrentProject_PreRender"
                                DataTextField="name" DataValueField="testProjectID" OnItemsRequested="rcbCurrentProject_ItemsRequested"
                                MarkFirstMatch="true" Filter="Contains" AllowCustomText="false" OnSelectedIndexChanged="rcbCurrentProject_SelectedIndexChanged"
                                OnClientDropDownOpening="cleanProjectDefaultSelection">
                            </telerik:RadComboBox>

      function cleanProjectDefaultSelection(sender, args) {
            if (sender.get_text() != "") {
                sender.set_text("");
                sender._filterText = "";
                sender.requestItems("");
            }
        }

fixed height radeditor

I’d like to have a fixed height radeditor which will limit content input after the boundary of the radeditor is reached. However, after setting the Height (500px), EnableResize(false), and AutoResizeHeight(false) parameters scrollbars continue to appear and the page still accepts input indefinitely.

Is there actually a way to limit the amount of input by fixing the height of a radeditor?

TemplateColumn with checkboxes

Hi,

I have tried to use your treelist with a template column for displaying a checkbox.

I get the result that the template column is displayed but now I don't know how to get the check event for the checkboxes.

I use the treelist as member of a usercontrol. There will be multiple instances of this usercontrol on the page.
The content of the treeview will be rebuilt completely on Page_Load of the usercontrol.

Don't know what's going wrong here. Hope you'll have a sample for fixing it.

Sincerely

René

'on Page Load of the UserControl

RadTreeList1.Style.Add(HtmlTextWriterStyle.Overflow, "auto")

RadTreeList1.Width = mWidth

RadTreeList1.Height = mHeight

RadTreeList1.EditMode = TreeListEditMode.InPlace

RadTreeList1.Enabled = True

XmlDataSource1.DataFile = Path & "RowData.xml"

RadTreeList1.Columns.Clear()

Dim tmplt As New Web.UI.TemplateBuilder

Dim selectColumn As New TreeListTemplateColumn

selectColumn.DataField = "selected"

selectColumn.EditItemTemplate = New CheckBoxTemplate("")

selectColumn.ItemTemplate = New CheckBoxTemplate("")

RadTreeList1.Columns.Add(selectColumn)

Dim boundColumn As New TreeListBoundColumn

boundColumn.DataField = "C2"

boundColumn.UniqueName = "C2"

boundColumn.HeaderText = "C2"

RadTreeList1.Columns.Add(boundColumn)

Private Sub RadTreeList1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.TreeListItemDataBoundEventArgs) Handles RadTreeList1.ItemDataBound

If TypeOf e.Item Is TreeListDataItem Then

Dim dataItem As TreeListDataItem = e.Item

Dim cb As Web.UI.WebControls.CheckBox

cb = dataItem.FindControl("templateColumnCheckBox")

AddHandler cb.CheckedChanged, AddressOf CheckBox1_CheckedChanged

How to add Telerik stylesheets to pages without Telerik controls

I know I'd done this once before, but cannot find where, and can't seem to find the code online anywhere either.

I have a site with Telerik controls in it. There is one page with out any telerik controls on it, but I'd like to use some of the styles from RadGrid in this page. I know there was a way to get the URL to include a specific control/skin stylesheet in your page so you could use the styles without having that particular control on your page.

What was the method to get the url?

Thanks in advance!
