Hello,
I am using a column chart to display information from a SQL database. The chart has to load after the user selects a value from a dropdown list, but the chart is loading as soon as the page loads and is giving me the error: "Data Not Available. Please call UltraChart.data.databind() after setting valid data source." After a value from teh dropdownlist is selected the correct information is displayed on the chart. But how do I get the chart to not load before selecting something from the dropdownlist.
I have used
Me.ChartGenre.Data.DataBind()
in the SelectedIndexChanged procedure of the DropDown. and not in the Page_load sub
Thanks.
You can try calling:
Me.ChartGenre.Data.DataSource = GetColumnData()
in the Page_LoadComplete.
Thank You.
I've tried that but the chart loads before any value is selected from the Dropdown. I need the chart to load after a value is selected from the dropdownlist.
Thanks
Alrit thanks, this works.
Ok. In this case you can try something like:
{
this.UltraChart1.DataSource = DemoTable.Table();
}
else
So the first time when the page loads the chart won't be displayed.
