Datagridview的數據報告中的空白報告

Question

所以，我試圖將datagridview的內容顯示到datareport中。但通過數據集鏈接報告後，生成的報告是空白的，代碼在這裏：

Dim dt As New DataTable 
    With dt 

    .Columns.Add("Roll") 

    .Columns.Add("Name") 

    End With 


    For Each row As DataGridViewRow In DataGridView1.Rows 

    dt.Rows.Add(DataGridView1.Rows(1).Cells(0).Value, DataGridView1.Rows(1).Cells(1).Value) 

    Next 


    Form2.ReportViewer1.LocalReport.DataSources.Item(0).Value = dt 

    Form2.ShowDialog() 

任何幫助表示讚賞。謝謝！

Answer 1

Dim rds As New ReportDataSource("YourDataSet", dt) 

Form2.ReportViewer1.LocalReport.DataSources.Clear() 
Form2.ReportViewer1.LocalReport.DataSources.Add(rds) 
Form2.ReportViewer1.RefreshReport()
