Hi,

I have multiple Tchart components vertically stacked as shown in the AVI movie

8-15-2010.zip: AVI movie showing the issue with TChart and Form's Scroll bars; (339.89 KiB) Downloaded 469 times

and in this sample project

WindowsApplication1.zip: VS2008 VB.Net Project; (19.29 KiB) Downloaded 424 times

.

When a user clicks on the TChart object that is partly invisible in the screen area, the scroll bar is automatically set to a position to display the clicked TChart object from the top. This is creating an issue if the TChart object is large that it can't be displayed in a 1024x768 screen area without vertical scrollbar. In such a situation, the TChart object always tries to display from the top and it is quickly becoming an annoyance to our users.

Is there a way i can separate the click event and scroll operation so that clicked TChart object won't always be displayed from the top.

Hope I clarified the issue reasonably with AVI screen movie and a project.

Any help is greatly appreciated.

Thanks,

Hello asupriya,

I fear that this problem is not a problem of TeeChart, because other controls of Visual Studios affected it too, as you can see it in next example with buttons controls:

Code: Select all

        private void InitializeChart()
        {

           Button[]  Buttons = new Button[3];

            for (int i = 0; i < Buttons.Length; i++)
            {
                Buttons[i] = new Button();
                this.Controls.Add(Buttons[i]);
                Buttons[i].Size = new Size(739, 436);
                Buttons[i].Location = new Point(0, i * 436);
                Buttons[i].Text = "Button:"+i.ToString();
            }

            this.AutoScroll = true;
        }

Moreover, I recommend you, consult next link to get more information about AutoScroll.
