Question

我做到最后一部分。不确定如何或应该如何添加到代码中。

public String DisplaySheetList()
{
    DataTable dt = new DataTable();
    GridView gv = new GridView();

    string sqlStatement1 = "SELECT cs.SheetId AS sheet_id, ltm.LocationType AS location_type, cs.PalletNo AS palletNo, cs.period AS period,cs.syncDate AS syncDate,cs.syncStatus AS syncStatus "
                + "FROM CountSheet cs JOIN LocationTypeMaster ltm ON ltm.LocationId = cs.LocationId " +
                " ORDER BY 1 DESC";
    SqlCommand sqlCmd1 = new SqlCommand(sqlStatement1, conn); 
    SqlDataAdapter sqlDa1 = new SqlDataAdapter(sqlCmd1);
    sqlDa1.Fill(dt);

     //What should i put here

     gv.DataBind();
}

我创建了表和视图，得到了查询并将其填入表中（如果我没有错）。它是完成还是我应该做的事情，以确保它在gridview中，所以我可以显示出来。

任何帮助都会很好，谢谢你们

Answer 1

Just Put：

gv.DataSource=dt;

代替我应该放在什么将数据表数据绑定到gridview

Answer 2

因此，在数据表中填写结果后

使dt成为gridview数据源。

//put it in the gridview datasource.    
gv.DataSource = dt;

您可以参考此MSDN page来设置gridview数据源

完成您的代码：

public String DisplaySheetList()
{
    DataTable dt = new DataTable();
    GridView gv = new GridView();

    string sqlStatement1 = "SELECT cs.SheetId AS sheet_id, ltm.LocationType AS location_type, cs.PalletNo AS palletNo, cs.period AS period,cs.syncDate AS syncDate,cs.syncStatus AS syncStatus "
                + "FROM CountSheet cs JOIN LocationTypeMaster ltm ON ltm.LocationId = cs.LocationId " +
                " ORDER BY 1 DESC";
    SqlCommand sqlCmd1 = new SqlCommand(sqlStatement1, conn); 
    SqlDataAdapter sqlDa1 = new SqlDataAdapter(sqlCmd1);
    sqlDa1.Fill(dt);

    //put it in the gridview datasource.    
    gv.DataSource = dt;

    gv.DataBind();
}

对数据表的SQL查询
