Hi Meppy

I need your help to set the width of report page dynamically based on screen resolution. My report is displayed inside a report window control and i want its size to be same as of report window. My present screen resolution(1600 by 900)
My report is inside the reportwindow.xaml control.
The report control fits itself according to screen resolution but not the report inside and so there comes a gap on the right side.

<Grid x:Name="LayoutRoot">

<Border CornerRadius="5" BorderBrush="#FF28607C" BorderThickness="1">


<Border.Background>



<LinearGradientBrush EndPoint="0.966,0.479" StartPoint="0.002,0.488">




<GradientStop Color="#FF65B1F0"/>




<GradientStop Color="#FFACE8F0" Offset="1"/>



</LinearGradientBrush>


</Border.Background>


<Grid>

<RowDefinition Height="22*"/>
                    <RowDefinition Height="423*" />
                </Grid.RowDefinitions>

I have a report handler class where I have tried to set the report viewer size.

 if (report != null)
            {

                if (_prvm != null)
                {
                    report.DataContext = _prvm;
                }

                report.QueryDetails += new EventHandler<QueryDetailsEventArgs>(report_QueryDetails);

                report.Run();
                if (_reportControl != null)
                {
                    _reportControl.reportViewer.PageSize = new Size(_reportControl.ActualWidth, _reportControl.reportViewer.PageSize.Height);

                    //foreach (var page in report.Pages)
                    //{
                    //    page.Size = new Dimension(_reportControl.ActualWidth, _reportControl.ActualHeight);
                    //}

                    _reportControl.reportViewer.Document = report;
                }
            }

 

But when the first time the report is loaded it doest change the page size and takes the default value. On consecutive calls the size is changed.

Please help me solve this issue.

Setting the size in the Prerender event is not a really good choice since this event is invoked multiple times for items in the report. Not to mention that setting the ReportViewer.PageSize itself causes a rendering of the report. The most natural place to put this code is in the SizeChanged event of the ReportViewer or its container - _reportControl.

I am trying this and it works as expected. Where were you calling this code originally?

Hi Meppy,
Sorry for the late reply. I was busy with another work so couldn't get time to reply earlier.

Thanks for the suggestion. I tried changing the page size in both reporttcontrol and report viewer size changed events but it didn't work. But as u suggested later to do the page size change after assigning the report to the document . I tried that and it worked.

                if (_reportControl != null)
                {

                    report.Prerender += new EventHandler<PrerenderEventArgs>(report_Prerender);
                    _reportControl.reportViewer.Document = report;
                    _reportControl.reportViewer.PageSize = new Size(_reportControl.ActualWidth, _reportControl.reportViewer.PageSize.Height);

                }

 

Thanks again!!
