Custom Gridline duplicated

[XTr33m]

Hi,

 

I have a custom gridline added to a WebForm. When I click on any toolbar button, the custom gridline gets duplicated in the legend box. Please see image attached.

 

Regards.

Please make sure you are adding the CustomLegendItem inside a !IsPostBack block; as otherwise the CustomLegendItem will be added in every callback request. Please refer to the code below:

 

[C#]

if  (!IsPostBack){ CustomLegendItem  cli =   new CustomLegendItem();cli.MarkerShape =   MarkerShape.HorizontalLine;cli.Color =   Color.Red;cli.Text =   "Custom Grid Line"  ;Chart1.LegendBox.CustomItems.Add(cli);}

 

Adding all the code that will be executed just once inside that block would be a good practice.

I hope this helps.
