hye, i always thinking why my report viewer does not visible true on event click even when I set it visible true. the report viewer will visible true if i not set it visible false on Page Load but set visible false on others event click.here's the code below.as you guys can see, only the Label1 will visible true on btnViewReport_Click but not the ReportViewer_TTFSSummaryBasedOnCountry. i hope someone can explain to me..i am new in this reporting. thanks :) p/s:this problems only happens in page load.

C#

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                BindDdlCountryValue();
                Label1.visible = false;
                ReportViewer_TTFSSummaryBasedOnCountry.Visible = false;
                
            }
        }

C#

protected void btnViewReport_Click(object sender, EventArgs e)
        {
            ReportViewer_TTFSSummaryBasedOnCountry.LocalReport.Refresh();
            Label1.visible = true;
            ReportViewer_TTFSSummaryBasedOnCountry.Visible = true;

It's kinda hard to understand but I assume you want the report be visible when you click a button? Then try this. Make the page do postback upon clicking button and handle the report visible setting at page load event.

thanks for the reply @ezra neil..i've try that,but still not working.im sorry if its kinda hard to understand.let me simplify this :)
example:
protected void btnViewReport_Click(object sender, EventArgs e)
{
reportviewer2.visible = true;
ReportViewer_TTFSSummaryBasedOnCountry.Visible = false;
}

protected void btnViewReport2_Click(object sender, EventArgs e)
{
reportviewer2.visible = false;
ReportViewer_TTFSSummaryBasedOnCountry.Visible = true;
}
above code is work..

but if in this situation

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{

ReportViewer_TTFSSummaryBasedOnCountry.Visible = false;

}
}
protected void btnViewReport2_Click(object sender, EventArgs e)
{

ReportViewer_TTFSSummaryBasedOnCountry.Visible = true;
}

the ReportViewer_TTFSSummaryBasedOnCountry.Visible = true; still visible as false.
