WinForms Form won't close on pressing X or Close() in C#
- by MadBoy
I'm having a bit weird problem with WinForm which seems to refuse to close for some weird reason. I've got very simple gui which sometimes doesn't react for me pressing X or when i use events on buttons it even reaches Close() and does nothing..
private void buttonZapisz_Click(object sender, EventArgs e) {
string plik = textBoxDokumentDoZaladowania.Text;
if (File.Exists(plik)) {
string extension = Path.GetExtension(plik);
string nazwaPliku = Path.GetFileName(plik);
SqlMethods.databaseFilePut(plik, comboBoxTypDokumentu.Text, textBoxKomentarz.Text, sKlienciID, sPortfelID, extension, nazwaPliku);
Close();
}
}
There are no events assigned to FormClosed or FormClosing. So how can I find out what's wrong. Sometimes X will work after the GUI is loaded but after i press Button to save some stuff to database it reaches Close() in that button event and it still is visible and does nothing. Can't use X, nor ALT+F4. I can go around GUI and choose other values for ComboBox without problem.
I call GUI like this:
private void contextMenuDokumentyDodaj_Click(object sender, EventArgs e) {
var lv = (ListView) contextMenuDokumenty.SourceControl;
string varPortfelID = Locale.ustalDaneListViewKolumny(listViewNumeryUmow, 0);
string varKlienciID = Locale.ustalDaneListViewKolumny(listViewKlienci, 0);
if (lv == listViewDokumentyPerKlient) {
if (varKlienciID != "") {
var dokumenty = new DocumentsGui(varKlienciID);
dokumenty.Show();
dokumenty.FormClosed += varDocumentsGuiKlienci_FormClosed;
}
} else if (lv == listViewDokumentyPerPortfel) {
if (varPortfelID != "" && varKlienciID != "") {
var dokumenty = new DocumentsGui(varKlienciID, varPortfelID);
dokumenty.Show();
dokumenty.FormClosed += varDocumentsGuiPortfele_FormClosed;
}
}
}
While I can't close GUI i can work on the main gui without problem too. I can open up same GUI and after opening new GUI i can quickly close it. GUI is very simple with few ComboBoxes,TextBoxes and one EditButton from Devexpress.
Edit: varDocumentsGuiPortfele_FormClosed code allows me to refresh GUI (reload ListView's depending on where the user is on now).
private void varDocumentsGuiPortfele_FormClosed(object sender, FormClosedEventArgs e) {
TabControl varTabControl = tabControlKlientPortfele;
if (varTabControl.TabPages.IndexOf(tabPageDokumentyPerKlient) == varTabControl.SelectedIndex) {
loadTabControlKlientPortfeleBezZmianyUmowy();
}
}
