Support for OnReportError and OnPreRender

[SalvadorFloresMichel]

Need to change the default export options like:

protected void repViewer_PreRender(object sender, EventArgs e)
{
try
{
FieldInfo info;
foreach (RenderingExtension extension in repViewer.LocalReport.ListRenderingExtensions())
{
if ((fldExportPDF.Value == "0" && extension.Name.Trim().ToUpper() == "PDF")
|| (fldExportXLS.Value == "0" && extension.Name.Trim().ToUpper().StartsWith("EXCEL"))
|| (fldExportDoc.Value == "0" && extension.Name.Trim().ToUpper().StartsWith("WORD")))
{
info = extension.GetType().GetField("m_isVisible", BindingFlags.Instance | BindingFlags.NonPublic);
info.SetValue(extension, false);
}
}
}
catch (Exception err)
{ ShowError(err.Message); }
}

And i have an error for missing parameters, but the regular exception does not show the error detail

protected void repViewer_ReportError(object sender, ReportErrorEventArgs e)
{
string strMensaje = e.Exception.Message;
if (e.Exception.InnerException != null)
{ strMensaje += ". " + e.Exception.InnerException.Message; }
ShowError(strMensaje);
}

You can change ReportViewer control settings in OnLoad method of your form and/or when you populate the datasource and parameters. As for error messages - those are (or at least should be) exactly the same as in original ReportViewer for compatibility reasons.
