{

InitializeComponent();

 

try

 

{

sqlDataSource1.SelectCommand =

 

".......";

 

 

 

this.sys2.ItemDataBound += new EventHandler(sys2_ItemDataBound);

 

}

 

 

catch (Exception)

 

{

 

 

throw;

 

}

}

 

 

void sys2_ItemDataBound(object sender, EventArgs e)

 

{

Telerik.Reporting.Processing.

 

SubReport subReport = (Telerik.Reporting.Processing.SubReport)sender;

 

Telerik.Reporting.Processing.

 

Report report = (Telerik.Reporting.Processing.Report)subReport.InnerReport;

 

 

 

if (report.ChildElements.Find("trasmissione", true).Length > 0)

 

{

subReport.Visible =

 

true;

 

}

 

 

else

 

{

textBox13.Visible =

 

true;

 

}

}

Please, help me. Thank you

It seems like you are doing a wrong cast. Debug and see where it is.
