Selected Index change firing on Text change

[Sreedath Kuttan]

Hi,
      I am using the RadCombobox.I want to fire an event only on Selected Index change and not on Text change.But the Selected Index change is firing on Text changed.

Is there any way to avoid this behaviour?

Hello Sreedath ,

RadComboBox first both of this events, because when the SelectedIndex is changed, the Text of RadComboBox  is changed too. However, SelectedIndexChanged event fires before TextChanged.You can use this and do not execute TextChanged event of the SelectedIndexChanged is already fired.

See the following code for an example:

public partial class DefaultCS: XhtmlPage
    {
        bool isChangedFired = false;
        private void Page_Load(object sender, System.EventArgs e)
        {
            Label1.Text = String.Empty;
            if(!IsPostBack)
            {
                RadComboBox1.LoadContentFile("combobox.xml");
            }
        }

        protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            if (RadComboBox1.SelectedItem != null)
            {
                isChangedFired = true;

            }

        }

        protected void RadComboBox1_TextChanged(object sender,  EventArgs e)
        {
            if (isChangedFired) return;

        }
}

Hi thank you for the reply.

But I don't want to fire any event on the Text change even the selected index change.Is there any way to accomplish this?

Hi Sreedath ,

RadComboBox does not support canceling the TextChanged event of RadComboBox .
It will always fire if the Text of  the RadComboBox is changed and you are hook on the TextChanged event.
