I have a button in user control and another button in report-viewer form to load the rdlc. Whenever I click the print button from my user-control and the validation passes, the click event handler in the report-viewer does work when data to be loaded are only a less row, but when data to be loaded is more than 1 page the click event handler does not fire properly in the load event handler, causing only a blank page in the report-viewer unless i manually click the button.
my codes: (In user-control)
private void btn_print_Click(object sender, EventArgs e)
{
pharm_printprev frm1 = new pharm_printprev(this);
frm1.Show();
}
public DateTime DTPicker
{
get { return _FromTime.Value; }
set { _FromTime.Value = value; }
}
public DateTime DTPicker1
{
get { return _ToTime.Value; }
set { _ToTime.Value = value; }
}
my codes: (Reportviewer Form)
private PHARM_OPDSALES _PHARM_OPDSALES = null;
public pharm_printprev(UserControl callingForm)
{
_PHARM_OPDSALES = callingForm as PHARM_OPDSALES;
InitializeComponent();
}
private void pharm_printprev_Load(object sender, EventArgs e)
{
lbl_print_refrsh_Click(sender, e);
}
private void lbl_print_refrsh_Click(object sender, EventArgs e)
{
string df1 = dm_dtepckr.Value.ToString("yyyy-MM-dd HH:mm:ss tt");
string dt1 = dm_dtepckr2.Value.ToString("yyyy-MM-dd HH:mm:ss tt");
this.dMDatableTableAdapter.Fill(this.DSdispense_sum.DMDatable, dm_dtepckr.Value = this._PHARM_OPDSALES.DTPicker, dm_dtepckr2.Value = this._PHARM_OPDSALES.DTPicker1);
ReportParameter[] Rparam = new ReportParameter[]
{
//new ReportParameter("Param1", dm_dtepckr.Value.Date.ToLongDateString()),
//new ReportParameter("Param2", dm_dtepckr2.Value.Date.ToLongDateString()),
new ReportParameter("Param1", df1),
new ReportParameter("Param2", dt1),
};
rptdsch1.LocalReport.SetParameters(Rparam);
rptdsch1.RefreshReport();
What could be the problem during the validation and why it only accepts less rows to trigger the button event handler in the reportviewer form?
