I am trying to get the Data Row of the node during the NodeDataBound event. I found the following documentation that I assume gets me this data. However, when I try to implement this and get "The type or namespace name 'DataRowView' could not be found (are you missing a using directive or an assembly reference?)" I have the Telerik.Web.UI namespace imported.

protected void radTreeViewTopicsGridFilter_NodeDataBound(object sender, RadTreeNodeEventArgs e)

{

DataRowView dataSourceRow = (DataRowView)e.Node.DataItem;

}

[Solved] Border on legend markers

Hi. I'm formatting a chart from the code behind. I've added some extra legend markers to my chart. The ones I've created have a nice grey border around the rectanglular boxes but the ones that are auto generated have no border. I can't seem to set the border no matter what I do. I've tried setting with the following:

RadChart1.Legend.Marker.Appearance.Border.PenStyle = System.Drawing.Drawing2D.DashStyle.Solid;

RadChart1.Legend.Marker.Appearance.Border.Width = 1;

RadChart1.Legend.Marker.Appearance.Border.Color = Color.Silver;

I haven't set any border properties for the ones I've created. I'm creating these as follows. I've also attached a screen. Thanks.

LabelItem item1 = new LabelItem();

item1.Marker.Appearance.FillStyle.MainColor = HexToColor("#2FBA2F");

item1.Marker.Appearance.FillStyle.FillType = FillType.Solid;

item1.Marker.Appearance.Figure = "Rectangle";

item1.TextBlock.Text = "Good";

TH vs. TD for table cells

When creating a table using the editor control, is there a way to switch a cell between td and th from the editor (without going into the raw HTML and changing it there)? If not, would there be an easy work-around to add this functionality?

Can't get Text value of items in ItemTemplate

I am attempting to get the ItemTemplate functionality to work.

I am using this code:

<telerik:RadComboBox ID="WeekEndingCB" Font-Size="Large" runat="server" OnSelectedIndexChanged="WeekEndingCB_SelectedIndexChanged"

OnTextChanged="WeekEndingCB_TextChanged" AutoPostBack="True" Style="width: 7.2em;">

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

<ItemTemplate>

Text: "<%# Eval("Text") %>"

</ItemTemplate>

<Items>

<telerik:RadComboBoxItem Value="10/3/2010" Text="10/3/2010"

/>

        <telerik:RadComboBoxItem Value="10/10/2010" Text="10/10/2010" />

</Items>

</telerik:RadComboBox>

I also tried DataBinder.Eval(Container.DataItem, "Text") and DataBinder.Eval(Container, "Text") as was instructed in a documentation article.

Either way, the Text of the items are not displayed in the drop down section when I click on the control.

The contents of the drop-down section are displayed as follows:
Text: ""
Text: ""

The expected contents would be:
Text: "10/3/2010"
Text: "10/10/2010"

The text of the selected item IS displayed as the selected item when an item is selected.

The control behaves as expected if I remove the ItemTemplate section.

How can I get the templates to work as expected?

RadWindow e is undefined error after RegisterStartupScript

I also opened a case on this but feel others might either (a) have insights or (b) get value out of the response. Thanks!
*************
I have a radwindow:

<telerik:RadWindow ID="StudentCheckListWindow" runat="server" Modal="True" AutoSize="true" EnableShadow="true"

Behaviors="Close" ReloadOnShow="true">

With a user control inside. The user control has a radgrid which lists a series of links. When one of the links is clicked it does a response.redirect to redirect the page.

During testing, I enabled IE script debugging and I am getting the attached error (saying e is undefined). I have tracked it down to the following scenario.

Page opens with RadWindow hidden
User clicks on a link which calls some JavaScript using RegsiterStartupScript (see below)
User then opens the RadWindow via oWnd.Show() syntax and RadWindow opens
Item is clicked and response.redirect is called. JavaScript error (attached) is thrown. Page DOES redirect fine.

If the item is clicked in the RadWindow before any RegisterStartupScript is called everything is fine. Also, if I run something RegisterStartupScript and then do a full page postback and then open the window everything is fine. It's almost like RegisterStartupScript is changing the page DOM and then the RadWindow is throwing an error which is fixed by a full postback.

My code block looks something like:

ScriptManager.RegisterStartupScript(Page, this.GetType(), "RedirectScript", "window.open('" + redirect + "');", true);

Thanks in advance!

RadScheduler not showing multiple appointments on one day

I have a day with multiple appointments, in Month view, it is showing the first 30 (VisibleAppointmentsPerDay setting) but when I switch to day view it is only showing one appointment.

We are using the DataSource property.

Everything thing I've seen indicates this should just work, so I don't even know where to start to figure out what is going on. Any direction would be of great help.

Edit: just tried it with fewer appointments (50 instead of over 100) and although the boxes get too small to read, it appears to have rendered all the appointments - is there a limit of some kind?

Hide editable item

Hi,
I have a bound grid to an entity datasource and can edit the data correctly.
One of the columns is a key (plantID) that is initially passed in from the load as a parameter on the datasource.
This key value needs to be defaulted to that same parameter value when I am adding a record....
I can do this fine using

       If (e.CommandName = RadGrid.InitInsertCommandName) Then
            'cancel the default operation
            e.Canceled = True
 
            'Prepare an IDictionary with the predefined values
            Dim newValues As System.Collections.Specialized.ListDictionary = New System.Collections.Specialized.ListDictionary()
            newValues("plantID") = Session("PlantID")
 
            'Insert the item and rebind
            e.Item.OwnerTableView.InsertItem(newValues)
        End If


When I go to add a new record there is a textbox with the correct session value for plantID in there and the value inserts ok...

What I want to do though is hide this text box when the grid is in edit mode - but I can't seem to do it without forcing the column to be read only - which obviously defeats the object...

Is there a way of using the default insert value as above but not displaying the textbox in edit mode?



Thanks in advance for any help...
