Radtreelist -expand at client side ..(Urgent)

Hi,

I have a RadTreelist inside RadTreeviewNodes.
My requirement is to expand RadTreelist at first level when expanding the treeview node.
I have given the code below

function

ClientNodeExpanded()

{

var treeView = $find("<%= tree.ClientID %>");

var nodes = treeView.get_allNodes();

for (var i = 0; i < nodes.length; i++) {

if (nodes[i].get_nodes() != null) {

alert(

'hi');

var treelist = nodes[i].get_nodes().getNode(i).findControl("RadTreeList1");

treelist.ExpandAllItems();

}

}

treelist.ExpandAllItems() is not workng ...how can I expand treelist at clientside?

list.ExpandAllItems();list.ExpandItemToLevel(1) ; these are the C# code for expanding treelist to all items and expand the firstlevel only.
what are the corresponding functions in clientside (javascript)?

Telerik controls layout

Hi,

I am creating a website, which needs to have the controls formatting and other stuff get loaded dynamically.Do the telerik control support this feature, out of the box.
Or alternatively do it have the options of creating some XML/XSL files from the controls layout, and loading from the same files to build the UI.

I have find the same utility in Dev-Ex controls for windows application, and was curious if the same is with telerik then it will encourage me to have your product on-board with us.

Thanks

Grouped series not generated - fix

At least for me it was. I have a generic list of data i'm binding to the RadChart, where each item contains:
Name, Quarter, Value

I'd like to display a bar for each quarter, grouped on the Name's. I can get it to display either by just name, or just Quarter, but not both. There are variable numbers of items per name, if there is not data present for a quarter there is no item in the list.

I assume from the examples and documentation that I would set,
    series[0].DataYColumn to Value
    DataGroupColumn to Quarter
    PlotArea.XAxis.DataLabelsColumn to Name

But that only yields one bar per Name. I also tried setting the DataManager.ValuesXColumn, but achieve only the same results.

For some reason though, not explicitly setting series[0].DataYColumn to anything gave me the output that I wanted. Rather counterinuitive, but it seems to have worked.

I am able to get the controls by adding manually on the Application page (registering Telerik). when i am adding as a user control as the way we will add user controls in ASp.net its not populating on the page. when i am trying to bind the Data to the RadGrid, i am getting the gridControl on the page but the data is not populating in the Grid. I tried with all the ways of bindings as per the Telerik SDK. In all the ways i am facing the same issue. And i didnt find anything in the log's also.

RadWindow open from server side

Hi

On my main page I have a button which brings up a radwindow when clicked. The button event on the server side does some processing which determines the URL querystring elements.

How can I set the URL on server side and then open the rad window?

Or is it possible for me to send the URL back to the client side and open from there?

Please help,

Thanks :-)

RAD TREEVIEW 1.1 performance problem

Hi Telerik treeview experts,
greetings..
We use rad treeview 1.1 in one of our asp.net 1.1 websites to populate hierarchical data.
Our customers are often encountering errors when they use the drag and drop feature of treeview control. This occurs when the number of nodes in the tree are more (100 + nodes).
Is that a known performance issue with telerik treeview control version 1 ?. Are there any solutions to this problem?
Appreciate if you could provide some guidance on this. thanks.

Regards,
Sreeraj

Item's visibility in edit and insert form

Hello,

I have created a grid wich shows datas following the value of a Combo Box (nomenclature name).
For many nomenclature i need only 2 colums in the grid but for one i need 5 columns.
So i created 5 columns in my grid and I change the "visible" attribute of the GridTemplateColumn when necessary to show or not the 3 last columns.
I have a problem when i click on the edit or Insert command. I have everytime 5 fields (even if the GridTemplateColumn is not visible)

How can i set the visible attribute of the field in the edit form ? I need to hide those three fields (isocountrycode, phoneID, nationality)

cs:

protected void RadGridNomenclature_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

        {

           [....]

            if (RadComboBoxNomenclaturesList.SelectedItem.Text.ToString().Equals("Code pays"))

            {

                RadGridNomenclature.Columns.FindByUniqueName("isoCountryCode").Visible = true;

                RadGridNomenclature.Columns.FindByUniqueName("phoneID").Visible = true;

                RadGridNomenclature.Columns.FindByUniqueName("nationality").Visible = true;

                RadGridNomenclature.Columns.FindByUniqueName("description").HeaderStyle.Width = Unit.Pixel(175);

            }

            else

            {

                RadGridNomenclature.Columns.FindByUniqueName("isoCountryCode").Visible = false;

                RadGridNomenclature.Columns.FindByUniqueName("phoneID").Visible = false;

                RadGridNomenclature.Columns.FindByUniqueName("nationality").Visible = false;

                RadGridNomenclature.Columns.FindByUniqueName("description").HeaderStyle.Width = Unit.Pixel(500);

            }

Issues with RadGrid and ItemCommand

Hello,

I'm using a RadGrid that is bound to a list of objects which gets set on page load (not postback).
RadGrid1.DataSource = myList;
RadGrid1.DataBind();

I've added columns that cause post backs such as imagebuttons and regular telerik button controls. When I click one of these buttons, the application throws an error in "RadGrid1_ItemCreated". The error occurs when attempting to access the grid data item and cast as my business object (Schedule). It seems the grid is no longer bound to my datasource since I'm no longer able to access this.

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
if (e.Item is GridDataItem) {
Schedule tempSchedule = (Schedule)e.Item.DataItem;

I thought it may need to be reloaded on page load, but when I put a break point on page load it doesn't hit. When clicking a button in the grid it seems to go straight to "RadGrid1_ItemCreated". Could you please give me some suggestions for correcting this issue? Do I need to cache my business object list "myList"?
