Question

User-1716951449 posted

the export button is not showing, even a proper rpt is generated.

it only show the report page navigation, and refresh buttons.

i have tried to increase the report viewer size, assuming it need bigger width to show that buttons, but it's not working.

at rare times, dunno how, it will show that button.

Hi Kelmen,

I want to confirm with you that is the export button not displaying completely or there are no options in export button?

check that your report is using any code like below or not. which is used to disable the export options in export button.

protected void ReportViewer_OnLoad(object sender, EventArgs e)
{
    //string exportOption = "Excel";
    //string exportOption = "Word";
    string exportOption = "PDF";
    RenderingExtension extension = ReportViewer1.LocalReport.ListRenderingExtensions().ToList().Find(x => x.Name.Equals(exportOption, StringComparison.CurrentCultureIgnoreCase));
    if (extension != null)
    {
        System.Reflection.FieldInfo fieldInfo = extension.GetType().GetField("m_isVisible", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
        fieldInfo.SetValue(extension, false);
    }
}

if it is using the code like this then try to modify the code to solve the issue.

also check that you had added the export controls like below.

            ReportViewer1.ShowExportControls = true;

if not then you can try to add it and then make a test.

based on testing, it is due to the client side viewer width/size

small window will not able to get that export button

for testing, i set it to something like 600/800 width, only it shows up

anyway, now i'm trying to do server rendering, once it done, i don't need the viewer at client side.
