I would like to bind the dynamically dataset to the rdlc. I can view the report if I use inline DataSource in ASPX file (static binding). However, if I use the following codes, the Report viewer keeps showing "Loading.." Image.
I have already check the dataset name and if I changed the dataset name to "Orders2", it shows me that required dataset "Orders" is not provided. So, I add the GridView on the form and test my DataSet. The dataset contains data and showing well with the GridView.
The problem is only with the Report and I could not bind data dynamically to the ReportViewer. Please help me. Thanks.
protected void Page_Load(object sender, EventArgs e)
{
DataSet ds = GetDataSet();
ReportDataSource rds = new ReportDataSource("Orders", ds.Tables[0]);
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(rds);
ReportViewer1.LocalReport.Refresh();
GridView1.DataSource = ds;
GridView1.DataBind();
}
private DataSet GetDataSet()
{
var conString = ConfigurationManager.ConnectionStrings["dotnetConnectionString"];
string strConnString = conString.ConnectionString;
SqlConnection conn = new SqlConnection(strConnString);
conn.Open();
string sql = "Select * FROM Orders";
SqlDataAdapter ad = new SqlDataAdapter(sql, conn);
DataSet ds = new DataSet();
ad.Fill(ds);
return ds;
}
ASPX codes are as below:
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<rsweb:ReportViewer ID="ReportViewer1" runat="server" Height="600px" Width="800px">
<LocalReport ReportPath="Reports\Report.rdlc">
<DataSources>
<rsweb:ReportDataSource />
</DataSources>
</LocalReport>
</rsweb:ReportViewer>
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
</form>
I have already solved my problem.
The problem is you need to add your codes under IsPostBack wrapping.
if (!Page.IsPostBack)
{
//your binding codes here
}
