Show data from datagridview to reportviewer C#

Question

I have a datagridview and I would like to pass data to reportviewer, so in this way I can print and export to pdf/excel easily. How can I do it please? or is there another solution to get my goal? Thank you! :)

Answer 1

Since you want to pass GridView data to ReportViewer, the first thing you got to do is retrieve the datasource of gridview as shown below:

BindingSource bs = (BindingSource)GridView1.DataSource;//You should first convert DataSourse into Binding Sourse
DataTable dt = (DataTable) bs.DataSource; //Get GridView data source to Data table

Now You got your GridView data in DataTable dt , you can bind ReportViewer to DataTable as shown below:

ReportViewer ReportViewer1 = new ReportViewer(); //Your ReportViewer Control
ReportDataSource rds = new ReportDataSource("DataSet1_Customers_DataTable1",dt); // ReportViewerDataSource : ReportViewer is to be bind to this DataSource
ReportViewer1.LocalReport.DataSources.Clear(); // Clear the Previous DataSource of ReportViewer
ReportViewer1.LocalReport.DataSources.Add(rds); //bind ReportViewer1 to the new datasource(Which you wish)
ReportViewer1.LocalReport.Refresh(); // Refresh the ReportViewer Control, ReportViewer1 in this case

thats all, you're done!
