Modify style in Server Side Event

[Artur]

Hi!

I wanted to modify style of RadCombo on server side, something like this:

01.protected void SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
02.    {
03.        var radCombo = sender as RadComboBox;
04.        var parent = radCombo.Parent;
05.
06.       // cuted...
07.
08.        int constLeft = 130;
09.        int avgTokenWidth = 73;
10.        int computed = constLeft + (avgTokenWidth * autocomplete.Entries.Count);
11.        radCombo.Style["Left"] = computed.ToString() + " px ! important";
12.    }

 

But it doesn't do anything. How to push these change to the client?

Hello Artur,

Generally, you can achieve this requirement using the client-side equivalent:
http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/client-side-programming/events/onclientselectedindexchanged

As for the server-side approach, you will need to use the correct CSS approach depending on your requirements:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo = sender as RadComboBox;
    combo.Style["margin-left"] = "100px";
}
