Hide Series at runtime

[Brent Hetland]

Hi

I am using Q2 2014 SP1 of Telerik Reporting.  My report currently contains a single Graph in the detail section.  It has a barSeries and two lineSeries.

However, there are times when I only want to show one of the two line series.

I'm binding the graph to a strongly typed list of objects and the object has a property on it that will let me determine if I want to hide the line series.

 

My specific example is this:

I am already binding my report's DataSource property to ReportItem.DataObject.BowlerValues  (this is my strongly typed list).

My graph might need to show Planned (bar), Forecast (line) and Actual (line) values.

A BowlerValue object has a property on it called "ShowForecast".

If ShowForecast is false, I will want to hide the Forecast Line Series.

 

How can I do this?  Can I use Bindings in any way?

Thanks,
Brent

Hello Brent,

You can hide Graph series using one of the following approaches:

• Use the Series.ConditionalFormatting property to set a conditional formatting rule for the current series which sets its visibility;
  
  
• Use the SeriesGroup.Filters property to apply a filter to some of the series;
  
  
• Create the Graph definition programmatically based on the value of the ShowForecast property;
  
  
• Create two separate Graph items using the report designer and change their visibility based on the ShowForecast property;

Hi Nasko,

Thanks.  While you did list some options and presented some links, you gave no real technical detail...

After I submitted the forum post, I went down the road of creating a duplicate graph which is your 4th bullet.  But you give absolutely no indication of how to do it.  I'm fairly new to Telerik Reporting, but I knew I could create a Binding that referenced my ShowForecast Field, and have it control the Visible property of the Graph.

Thanks again for the reply.  I'd encourage you next time, to give more detail.
