晚上,我在一个静态类中有以下代码,它可以帮助我的 userInterface 部分类。每当我到达检查组合框/文本框是否可见的部分时:
if (cb.Visible == true)
&
if (tb.Visible == true)
即使控件在表单上可见,它也总是错误的。
有任何想法吗?
谢谢
public static bool VerifyTableLayoutControlsContainData(TableLayoutPanel tlp)
{
foreach (Control input in tlp.Controls)
{
ComboBox cb = input as ComboBox;
if(cb != null)
{
if (cb.Visible == true)
{
if (string.IsNullOrEmpty(cb.SelectedItem.ToString()))
{
return false;
}
}
}
TextBox tb = input as TextBox;
if (tb != null)
{
if (tb.Visible == true)
{
if (string.IsNullOrEmpty(tb.Text))
{
return false;
}
}
}
}
return true;
}

用户界面代码
private void uiBtnDataVerification_Click(object sender, EventArgs e)
{
if (VerifyingData != true)
{
AllInputsContainDataCsvFileVerificationStage = true;
//Check all inputs have something in them
InputsContainDataCsvFileVerificationStage();
if (AllInputsContainDataCsvFileVerificationStage == false)
{
UiHelper.UpdateLog("One or more inputs has not been specified.", uiTxtOperationLog);
return;
}
...
}
else
{
//Cancel permanent cancellation token.
}
}
public void InputsContainDataCsvFileVerificationStage()
{
....
if (UiHelper.VerifyTableLayoutControlsContainData(uiTableLayoutPanelColumnDataTypes)) { }
else
{
AllInputsContainDataCsvFileVerificationStage = false;
}
....
}
原始代码在 UiHelper 类中
Edit2:根据汤姆斯的建议,我做了以下更改
public userInterface()
{
InitializeComponent();
uiTableLayoutPanelColumnDataTypes.VisibleChanged += new EventHandler(notifyMe);
uiCBColumn1DataType.VisibleChanged += new EventHandler(notifyMe1);
SortedColumnNames = new List<TextBox>();
SortedDataTypes = new List<ComboBox>();
AllInputsContainDataCsvFileVerificationStage = true;
}
public void notifyMe1(object sender, EventArgs e)
{
bool temp = uiCBColumn1DataType.Visible;
MessageBox.Show("its been changed");
}
public void notifyMe(object sender, EventArgs e)
{
bool temp = uiTableLayoutPanelColumnDataTypes.Visible;
MessageBox.Show("its been changed");
}
在单击按钮之前,我检查了 cb1 可见性属性设置为什么,它是 True。当我尝试通过原始方法进行检查时,我仍然会出错。
我难住了!!

似乎当我单击第二个选项卡时,组合框的可见属性 = false。
有谁知道为什么会这样??
