Overview Control using

[Alberto Munoz]

Hi!

I have read the help page http://help.syncfusion.com/ug_74/diagramwin/OverviewControl.html but I don't know use Overview Control.

I have a big diagram and I want to show only half of it.

Could you show me code examples to use overview control?

Hi Alberto,

Please elaborate your requirement of what exactly you are trying to achieve. Do you mean that the only half of the diagram alone should be displayed in the diagram control and the remaining should be displayed only on demand(by moving viewport on Overview control).

Hi Alberto,

Please check the following client script which when called will set the scroll position of DiagramWebControl thereby letting the user to view the desired area.



function ScrollPosition() {
_sfDiagramWebControl1.SetScrollLeftPosition(40);
_sfDiagramWebControl1.SetScrollTopPosition(40);
}

I need to Zoom the diagram. I have tried with:



function Zoom() {
_sfDiagramWebControl1.Zoom(75);
}

but I get a exception:

_sfctl00_ch_DiagramWebControl1_ChangeTextPopup is not defined

Hi Alberto,

I have tested this issue in a sample and I found that the zooming works properly without any exceptions as you have mentioned. Please provide me a sample that reproduces this issue.
