我有一個方法來重置我的表單上的一些控件。除了名爲「tsStatusLabelInfo」的ToolStripStatusLabel
之外,我可以使用該方法。該控件不會傳遞給resetForm()
方法。如何更新ToolStripStatusLabel文本通過表單上的所有控件
我相信它是StatusStrip控件的一部分,但我還沒有弄清楚如何訪問ToolStripStatusLabel
控件來更新文本。
private void resetButton_Click(object sender, EventArgs e)
{
Utilities.resetForm(this);
}
public static void resetForm(Control form)
{
foreach(Control c in GetOffSprings(form))
{
if (c.Name == "folderTextBox")
{
((TextBox)c).Clear();
}
else if (c.Name == "mfrListTextBox")
{
((RichTextBox)c).Clear();
}
else if (c.Name == "mfrListDataGridView")
{
((DataGridView)c).DataSource = null;
}
else if (c.Name == "onlyRadioButton")
{
((RadioButton)c).Checked = true;
}
else if (c.Name == "usRadioButton")
{
((RadioButton)c).Checked = true;
}
else if (c.Name == "otherYearsCheckedListBox")
{
((CheckedListBox)c).SetItemCheckState(0, CheckState.Unchecked);
((CheckedListBox)c).SetItemCheckState(1, CheckState.Unchecked);
}
else if (c.Name == "yearComboBox")
{
((ComboBox)c).Text = string.Empty;
}
else if (c.Name == "tsStatusLabelInfo")
{
//Control never pass
}
else if (c.Name == "statusStrip1")
{
// Exception:Object reference not set to an instance of an object
((StatusStrip)c).Controls["tsStatusLabelInfo"].Text = string.Empty;
}
}
}
//Loop through the control recursively getting all child controls
public static IEnumerable<Control> GetOffSprings(this Control @this)
{
foreach(Control child in @this.Controls)
{
yield return child;
//MessageBox.Show(child.Name);
foreach (var offspring in GetOffSprings(child))
{
yield return offspring;
}
}
}
這樣做 - 我將代碼更改爲 ((StatusStrip)c).Items [「tsStatusLabelInfo」] .Text = string.Empty; 感謝您的幫助! – Joaquin
