    I try to use DropDownList with datasource, but is not working as expected.

    When I Clear() the BindingSource, the RAD component still have "Text" with last item displayed which is abnormal.

    Please see the code, the normal windows ComboBox works as expected.


    Any fixes?

    public partial class Form1 : Form
        List<string> list = new List<string>();
        BindingSource bsource = new BindingSource();
        public Form1()
            bsource.DataSource = list;
        private void Form1_Load(object sender, EventArgs e)
            //Set list dataSource
            comboBox1.DataSource = bsource;
            radDropDownList1.DataSource = bsource;
            //Now add an element via Binding object
        private void button1_Click(object sender, EventArgs e)
        private void button2_Click(object sender, EventArgs e)

    Hi Robert,

    Thank you for writing.

    I have logged this issue in our Feedback Portal. You can track the item for status changes and add your vote for it here.

    To workaround the issue you can manually clear the text:
    private void radButton2_Click(object sender, EventArgs e)
        radDropDownList1.Text = "";

    Your Telerik Points have been updated for this report.

    Should you have any other questions do not hesitate to ask.
