                </Legend>
            </telerik:RadChart>

Which displays fine on first databind, but on rebinding with new data on this button press the old chart stays on screen?

protected void searchButton_Click(object sender, EventArgs e)
    {
        Report report = new Report();
        RadChart1.DataSource = report.RetrieveSSPhraseDailysp(keyword, 99, 1, fromRadDatePicker.SelectedDate, toRadDatePicker.SelectedDate);
        RadChart1.DataBind();

        phraseGridView.Rebind();
    }

What am i doing wrong?

Thanks
Matt

Hello Matthew,

I can see you are using a gridview too. Does it display the new values? Can you please attach a runnable page (you can use a dummy datasource or an in-memory datatable), which reproduces it, so we can debug it and get back to you? Thanks.

Best regards,

Hi Ves,

My Bad!!!

I am using AjaxManager (newbie) AND I had not wired up the chart (as well as the grid which was working) to the Button press, your post triggered the realisation ;) workings beautifully now.

Thanks
Matt
