New to telerik and trying to use the RadTreeview to replace our old tree. I am trying to display more that one image on a node.

something like this
    
Root
    |
    ------Item1 (Image1) (Image2) (Image 3)
    |
    ------Item1 (Image1) (Image2) (Image 3)

Is this possible? if so, can you provide an example of how to do?

i need to know how to dynamically sort the column's data.i just placed a radgrid and dynamically binded through the following...


con = new SqlConnection("Data Source=ServerName;Initial Catalog=Databasename;User ID=sa;Password=*******");
        con.Open();
        cmd = new SqlCommand("select * from TableName where Department ='FieldName'", con);
        reader = cmd.ExecuteReader();
        RadGrid1.DataSource = reader;
        RadGrid1.DataBind();
        con.Close();

and i aslo enable the radgrid properties such as sorting , paging, auto generate columns, at the design time itself ...when i click on the column header at runtime .. it shows error like below..

Server Error in '/' Application.

Hi,
Currently in one of our application we are planning to use RadRotator for rotating the items (e.g. Images) on click of left , right buttons. I found this can be achieved by setting the RotatorType="Buttons" in RadRotator. We have a requirement that, the number of items displayed and number of items scrolled on click of left or right button is configurable. From documentation i figured out how to configure the number of items to be displayed (i.e. by setting ItemWidth and Width properties appropriately). Is there any way to configure the number of items to be scrolled on click of right or left button.
Thanks in advance.

I'm looking for a TriState CheckBox control but there isn't one in the Telerik Asp.net Ajax Controls.

The RadTreeView had a TriState checkbox, so isn't it possible to use that TriState?

If not, any plans on releasing a TriState checkbox?

Is it possible to change the currency despite the cuture(only currency). Becouse i have an app that changes the language depending on culture info but i wan`t to keep the same currency.

When i change only the currency it doesn`t work:

CultureInfo currentCulture = new CultureInfo(System.Threading.Thread.CurrentThread.CurrentCulture.LCID);
currentCulture.NumberFormat.CurrencySymbol = "zł";
System.Threading.Thread.CurrentThread.CurrentCulture = currentCulture;

Hey Guys,

We are facing the problem with the RadComboBox that if the value of the box contains quotes, the value is gone after a postback.
It looks like this is the only character which makes trouble.
Everything else works as expected.

Is this a known issue and any workaround?

Cheers,
Thomas

Hi,

I have a timer which refreshes the browser every 30 seconds. If I try to drag a task from Radgrid to RadScheduler, at that point if the timer refreshes the browser the task freezes/getting stuck somewhere. (Please see screenshot). It is disappearing when I hit F5.

How can I fix this issue?

Thanks in advance
