I'm using The Viewer's reporting feature in Winform, Which has the ability to export pdfs, but before clicking on the export to pop up the save window, a "exporting" window will appear, I want to hide this window but I can't solve it after trying some methods, who can help me? Click on the screenshot of the question

I tried something but couldn't solve it：

foreach(Form item in Applictaion.OpenForms){
    //Hide this window 
    if(item.Title == "正在导出")
        item.Hide();  
}

I also tried this:

if (this.reportViewer1.Controls.Find("exportDialog", true)[0] is Form form)
    {
        //"exportDialog" may be the Name property value I tried to find in the source code, but it was prompted that "index out of range"
        form.Hide();
    }
