Hi all,

can someone tell me what it is the best way to browse all nodes of a RadTreeView?

I'm using the following code:

foreach (RadTreeNode oNode in oTreeView.Nodes)

{

Label oLbl = (Label)oNode.FindControl("spnDesignation");

oLbl.Visible = bShow;

}

but it is just catching the root node.

Thanks,
Bruno

Questions

I have one database with two tables, named Event1 and Event2.

I now have:

<telerik:RadScheduler runat="server" ID="RadScheduler1" Width="748px" SelectedDate="2007-03-30"<br> DayStartTime="08:00:00" DayEndTime="18:00:00" DataKeyField="ID" DataSubjectField="Subject"<br> DataStartField="Start" DataEndField="End" DataRecurrenceField="RecurrenceRule"<br> DataRecurrenceParentKeyField="RecurrenceParentID" <br> DataSourceID="EntityDataSource1" ><br> <ResourceTypes><br> <telerik:ResourceType KeyField="ID" Name="Event1" TextField="Text1" ForeignKeyField="ID"<br> DataSourceID="EntityDataSource1" /><br> <telerik:ResourceType KeyField="ID" Name="<span style="font-size: 14px; ">Event2</span>" TextField="Text2" ForeignKeyField="ID"<br> DataSourceID="EntityDataSource2" /><br> </ResourceTypes><br> </telerik:RadScheduler>

I have some questions:

1. What is the method GetResources(ISchedulerInfo schedulerInfo) for? What would I get if I override it?
2. In the code above, I know that the KeyField is the primary key of the table, the ForeignKeyField is the foregin key, but what column of the table represents the TextField attribute?
3. How to define the tables as different resources?
4. How to make different color of the events from the second table but not with javascript, but as resources?

Add root nodes on client

Hi,

in certain cases I want to reload specific nodes. When it's about nodes under other nodes, this is no problem.
I collapse the node, remove the children, set the expand mode back to webservice and expand the node.
The nodes are loaded-on-demand by the tree.

But when it is about the root nodes, I have to do it myself. I call the webservice, get the nodes but how do I add them to the tree?
This is what I found in the forums (but the post was from 2008).

function AddRootNodesToTree(nodes, tree) {

tree.trackChanges();

tree.get_nodes().clear();

for (var node in nodes) {

var dynamicNode = new Telerik.Web.UI.RadTreeNode();

dynamicNode._loadFromDictionary(nodes[node]);

tree.get_nodes().add(dynamicNode);

}

tree.commitChanges();

}

The nodes from the webservice are correctly converted to RadTreeNode and added. But the attributes of the nodes aren't transferred to the RadTreeNode.

So, how can I add nodes, which I fetch from a webservice, to the tree as root nodes?

Thanks!

Edit: I added screenshot from the Google Chrome debugger where you can see the difference. The webservice returns in both cases RadTreeNodeData and I didn't see any difference regarding the attributes.

Cannot insert using user control

Hi
I have been trying to use the RadGrid to maintain emergency contact information. I am having a difficulty getting my user control to perform the actual insert. I have looked through the documentation and still cannot figure out what I am doing wrong. My grid comes up ok and when I click on Add new record, my user control comes up and I can fill in the information. I even have validators on the page that fires ok. When I click the Insert button, the form returns and no record is added. I handle the InsertCommand event on the server side but it does not seem to get there. I really have an urgent need to move past this problem, so your urgent response here is very welcome.

Any leads will be very helpful. Here is my code

OnRowDblClick for DetailTable Rows Only?

I know I can register an event using ClientSettings.ClientEvents.OnRowDblClick, but this seems to fire for every row including any DetailTable instances in my grid.

Is there any way to either register a different event, or differentiate in some way (using a JavaScript function possibly) whether the event was fired from a master or detail table? Thanks!

RadCalendar with RadTooltipManager and RadRotator

Hello,

I have setup a RadCalendar with a RadTooltipManager using the examples here:
http://demos.telerik.com/aspnet-ajax/tooltip/examples/tooltipcalendar/defaultcs.aspx

In the OnAjaxUpdate event i instantiate a control and set a public property on it (a collection of items)
adds it to the container: e.UpdatePanel.ContentTemplateContainer.Controls.Add(details);

and then bind the datasource in the control PreRender event.

When I hover over a day with an event the first time, I see a blank tooltip with the scrollers aligned tight to eachothers to the very right of the tooltip (firefox) ... In chrome nothing appears at all, but in FF, it all comes up correctly on the second time i hover over.

I don't experience any of this in IE9.
Could it be some z-index issue?
Thanks in advance :)

Any ideas?

MarkFirstMatch problem with IE 8

Hi,

I use RadControls for ASP.NET AJAX Q1 2011 version. My problem is that MarkFirstMatch = true property of RadComboBox does not work in IE 7 & IE 8. I have tested with IE9, Opera, Safari, Firefox, Chrome and every works fine there.
I have read the below article:

http://www.telerik.com/community/forums/aspnet-ajax/combobox/patch-ms-update-kb2586448-breaks-radcombobox-markfirstmatch-in-versions-older-than-2009-3-1314-inclusive.aspx

and I don't know if that is the case as it refers to older versions.

Do you have any idea how to solve it?

Thank you in advance,

Update events not firing

Hi,

I have been trying to add a edit functionality to a grid but the update events are not firing at all. Even the OnItemCommand, it fires with the CommandName "Edit" when you click the edit button. However, when you click Update, the event doesn't fire up.

I tried a few different codes (available on the forums) but no luck, this is my final code (using <FormTemplate>).

I want to manually update fields using my dal project.
