Hi.
My site doesn't refresh at all - all content is loading dinamically inside of Update Panel (standart ajax)

I tried to use Treeview, after loading page context (dinamicaly) treeview do not shows correctly - treeview styles/scripts are not loaded (it shows only top nodes with 'li' tag dots).
Only full page refresh help with this.
However I want to load all required scripts/styles dinamicaly

Is there any way to help me (without changing overall site's behaviour) ?
p.s. sorry for my english

Retrieve dock height in script

Hi,

How do I get the new height of the dock pane when user expands or collapses it? I tried the following methods but none of them work.Where can I find documentation for RadDock client API?

function OnClientCommand(sender, eventArgs)
{
    if (eventArgs.Command.get_name() == "ExpandCollapse")
    {
        sender.get_Height(); // return null.
        eventArgs.Command.get_RadDock().get_Height(); // return null.
        eventArgs.Command.get_RadDock().get_NewHeight(); // object doesn't support this method.
        eventArgs.get_OldHeight(); // object doesn't support this method.
        eventArgs.get_NewHeight(); // object doesn't support this method
    }
}

Thanks.

Selection out of range error

I'm getting a Selection Out of Range error when trying to do something very simple with the DropDown control.

Based on a radio selection list, the items in the drop down list should change. The items are retrieved from a datasource, however i manually add the "All" item to the list. The code is below:

    
             void JobsList_SelectedIndexChanged(object sender, EventArgs e) 
        
                { 
        
                    FilterCombo.AppendDataBoundItems = true; 
        
                    FilterCombo.Items.Clear(); 
        
                    RadComboBoxItem myItem = new RadComboBoxItem("All", "-1"); 
        
                    FilterCombo.Items.Insert(0, myItem); 
        
                    FilterCombo.Items[0].Selected = true; 
        
                    if (JobsList.SelectedValue == "1") 
        
                    { 
        
                        FilterCombo.DataSource = TechniciansSource; 
        
                        FilterCombo.DataTextField = "TechName"; 
        
                        FilterCombo.DataValueField = "TechnicianId"; 
        
                        FilterCombo.DataBind(); 
        
                    } 
        
                    else 
        
                    { 
        
                        FilterCombo.DataSource = SuburbSource; 
        
                        FilterCombo.DataTextField = "Suburb"; 
        
                        FilterCombo.DataValueField = "SuburbId"; 
        
                        FilterCombo.DataBind(); 
        
                    } 
        
                }

Similar code is called when the page first loads (!IsPostBack), and there is no problem. The exception is thrown once it tries to execute the FilterCombo.DataBind() method.

Any help would be appreciated

Changing styles of parent rows based on detail tables when not expanded

Hi,
I am trying to apply some custom styles to rows based on values that are present in their child rows. I can only get this to work correctly if i have the HierarchyDefaultExpanded property set to true. By doing this, the radgrid looks very cluttered. Basically, i need to find out if there is a way to tell if a row has been expanded or not.

My code is below:

    
              void RadGrid1_PreRender(object sender, EventArgs e) 
        
                { 
        
                    foreach (GridDataItem itm in RadGrid1.Items) 
        
                    { 
        
                        if (itm.OwnerTableView.DataSourceID == "JobCodesSource") 
        
                        { 
        
                            //Go through each of the items in there 
        
                            int numChildRows = itm.ChildItem.NestedTableViews[0].Items.Count; 
        
                            int numChanged = 0; 
        
                            foreach (GridDataItem childItm in itm.ChildItem.NestedTableViews[0].ItemsHierarchy) 
        
                            { 
        
                               string TechName = "Bill Gates"; 
        
                                if (childItm["TechnicianId"].Text != Techname) 
        
                                { 
        
                                    childItm.CssClass = "MyCustomRowClass"; 
        
                                    numChanged++; 
        
                                } 
        
                                TechniciansSource.SelectCommand = oldSelect; 
        
                            } 
        
                            if(numChanged == numChildRows) 
        
                                itm.CssClass = "MyCustomRowClass"; 
        
                        } 
        
                    } 
        
                }

The problem is that when the row is not expanded, the count is 0.
0 is a valid count of rows as well, as some rows will not have any items beneath them, and I want their style to also change. Is their someway of finding out all the childitems of a row without expanding the row?

I already tried setting the HeiarchyLoadMode for the child table to be client but that didnt help either.

I basically need two things:

1. A way of knowing whether or not the row is expanded

2. The child items of the row when it is not expanded

Thanks,

Fayez

JavaScript Error on a RadWindow inside of a RadAjaxPanel

I have a master page that contains a RadScriptManager, RadAjaxManager, RadAjaxPanel, and an asp:UpdateProgress. Inside the RadAjaxPanel is a couple asp:ContentPlaceHolders. On one of the pages that have content for these ContentPlaceHolders I have a RadGrid that contains some GridTemplateColumns.

Now to the actual error...
Inside one of the GridTemplateColumn I am using a RadWindow thru Javascript to open a preview window for an item in the grid like so:

window.radopen('PreviewTemplate.aspx','PreviewWindow')

If my RadAjaxPanel1.EnableAJAX property is set to true I receive the following Javascript Error: Line 4911 Error: length is null or not an object

If the property is set false which disables ajax then the preview window works perfectly.

I was wondering if this is a known bug and if a hotfix is available to resolve it as of yet. I have browsed the forum in prometheus Ajax and Window sections but have not found a resolution, maybe I missed something though.

AutoPostBack property

Will be there an AutoPostback property in the ComboBox?
Or how can I simulate the behavior? With the "SelectedIndexChanged" event?

I had a page with some comboboxes. When one of them changed, the page was post backed and the grid on the page was refreshed.

Thanks

Preview Content is centered

I have an editor in my page and the contents of the editor (in edit mode and preview mode) are centered by default. I don't want this. The editor is in a table and nothing else in the cell is centered. I have attempted to put various tags around the editor to get everything left aligned but nothing seems to work.

I managed to get the edit mode left aligned by creating a ContentAreaCssFile and specifying the text alignment. However, the preview is still aligned centered instead of left aligned.

Any workarounds for this?
