There're a class named 'RadDocument' and a class named 'HtmlFormatProvider', through which we can convert a html stream to an instance of class 'RadDocument', then we can get an xaml string using 'XamlFormatProvider'. Are there any equivalents in ASP.NET AJAX library instead of 'HtmlFormatProvider' and 'XamlFormatProvider' to support the conversion between html and xaml?

Check controls state on post back and Page Navigation

Hi there,

I need samples for two scenarios:

1)	I have RadListBox, based on the values selected, others controls (RadTextBox, RadComboBox,RadListBox, RadRadioListBox etc)
	 will be visible to the user. If user made some changes on these controls and again changed the values of Main RadListBox, 
	It should prompt the user that ‘ You have made some changes but not saved, do you still want to move away(select a new item)?’.

2)	Whenever user navigate away from one page to another page, it should prompt like: ‘Do you want to move away?’

Thanks

Regards,
Mayil

C# lamda expression to get list of values of cehcked items

At the moment I have to break down this simple operation in two parts, I am sure the would be a better way is hiding from me :

List<int> selectedValues= new List<int>();

.

IEnumerable<RadComboBoxItem> checkedItems = from checkedItem in cblMagistrateCourts.Items.ToList()

where checkedItem.Checked == true

select checkedItem;

foreach (RadComboBoxItem item in checkedItems)

{

if (item.Checked)

selectedValues.Add(Convert.ToInt32(item.Value));

}

On our local environment,a grid with 758 records is generating ViewState size of 0.42 MB.
I am using the RadGrid.ViewStateSize Property to get the size of ViewState.

So,is this error due to large amount of Viewstate that is been generated?.
Shall I disable the Viewstate on the Grid and re-design the Grid?
Please can you provide me any pointers?

Regards

Change the left axis to descending order

I have a unique situation where I want the left Y axis in my line chart to show the values so that the larger number is at the bottom... for example 100 up to 0, vs the standard format of a bottom 0 line that increments up to 100. Basically I just want to reverse the order of the left Y axis data.

Is there any easy way to do this?

Any help is greatly appreciated.
