[Solved] Checkbox in nested grid should check children

I have a 3 level nested RadGrid.
All levels have checkboxes.
If the checkbox at any level is checked, the checkboxes of its children (and grandchildren) should also be checked.
How can I accomplish this?

How to get invisible childitem from client side

Hi, Expert,

I create a RadMenuItem and set the item to invisible.
On my client side code,

I would like to set the radmenuitem to visible.

{
var menuItem2 = menu1.FindItemByText('Paste');
.......

}

The FindItemByText can not get that item. (Only show visible item)

I also try to use menu1.Items, the invisible is not there either.

Can anyone have idea how to get invisble item from menu on client side code?

Thanks.

ListView Binding Twice? Strange Behaviour

I have a very simple RadListView populated from a DataSet:

Data:

    
            HeadingOne  HeadingTwo  DataValue  
        
            First       Second      Data Value  
        
            First       Second      Data Value  
        
            First       Third       Data Value  
        
            First       Third       Data Value  
        
            First       Third       Data Value

ListView:

    
            <telerik:RadListView   
        
                ID="MyListView"   
        
                runat="server"   
        
                OnNeedDataSource="MyListView_OnNeedDataSource">  
        
                <ItemTemplate> 
        
                    <%# InsertHeadingOne() %> 
        
                    <%# InsertHeadingTwo() %> 
        
                    <p><%# Eval("DataValue") %></p>  
        
                </ItemTemplate> 
        
            </telerik:RadListView>

I thought I was being very cunning in my grouping efforts. The two method calls above are:

    
            string lastHeadingOne = string.Empty;  
        
            string lastHeadingTwo = string.Empty;  
        
            protected string InsertHeadingOne()  
        
            {  
        
                string currentHeadingOne = Eval("HeadingOne").ToString();  
        
                if (currentHeadingOne.Length == 0)  
        
                {  
        
                    currentHeadingOne = string.Empty;  
        
                }  
        
                if (this.lastHeadingOne != currentHeadingOne)  
        
                {  
        
                    this.lastHeadingOne = currentHeadingOne;  
        
                    return string.Format("<h1>{0}</h1>", currentHeadingOne);  
        
                }  
        
                else 
        
                {  
        
                    return string.Empty;  
        
                }  
        
            }  
        
            protected string InsertHeadingTwo()  
        
            {  
        
                string currentHeadingTwo = Eval("HeadingTwo").ToString();  
        
                if (currentHeadingTwo.Length == 0)  
        
                {  
        
                    currentHeadingTwo = string.Empty;  
        
                }  
        
                if (this.lastHeadingTwo != currentHeadingTwo)  
        
                {  
        
                    this.lastHeadingTwo = currentHeadingTwo;  
        
                    return string.Format("<h2>{0}</h2>", currentHeadingTwo);  
        
                }  
        
                else 
        
                {  
        
                    return string.Empty;  
        
                }  
        
            }

But when I run the page, I get this output:

    
            Second  
        
            Data Value  
        
            Data Value  
        
            Third  
        
            Data Value  
        
            Data Value  
        
            Data Value

What I should be getting is this?:

    
            First  
        
            Second 
        
            Data Value  
        
            Data Value  
        
            Third 
        
            Data Value  
        
            Data Value  
        
            Data Value

When I step through in debug I see the correct strings being returned but for the 5 rows in the DataSet, there are 10 calls to each method! It seems the second pass wipes the values from the first - but then, if that is the case, how did the Heading Twos get returned? I'm confused :)

Very strange. It works really well for the level 2 headings but not at all from the level one. Can anyone help?

Many thanks in advance,
Richard

Was this made with RadMenu?

I like the look of the dropdown menu on "All Products" at the top of this page: http://demos.telerik.com/aspnet-ajax/menu/examples/overview/defaultcs.aspx

Was that done with RadMenu? Any code examples out there for something like that?

Thanks,

Also when i select something from 1st combo, then from 2nd (2nd combobox datasource is based on 1st combobox selection)

and after that try to insert some date into RadMaskedTextBox nothing happens (no text is inserted, no exceptions is thrown).

Here is aspx code (from form to /form for easy copypaste =] )

                    }         

would be glad to hear how to fix this behaviour.

Thank You !

Hide SlidingPane header

I don't know what you call the part of a SlidingPane that contains the close and dock buttons, but I'd like to hide it.
Server-side would be preferable.

TIA,

Why is GridDragDropEventArgs.DraggedItems Type of IList?

Is there a valid reason that GridDragDropEventArgs.DraggedItems is an IList instead of a GridItemCollection?
May I suggest, the items collections in handlers and helper properties alike should conform.

The fact that they don't conform present a challenge for generics and doesn't make any sense to me.
