c# - c#不要在表单加载时调用editValueChanged

Question

由于我从数据库加载数据并将其放入 FormLoad 上的 DevExpress TextEdit 控件中，因此调用了事件处理程序 TextEdit_EditValueChanged。是否可以在事件处理程序中进行任何检查，或防止引发事件？

Answer 1

像这样的东西：

bool dataLoaded = false;

private void LoadData()
{
    // do the loading and set the Text property of the textEdit
    dataLoaded = true;
}

private void TextEdit_EditValueChanged(object sender, EventArgs e)
{
    if (dataLoaded == false) return;
    // the code after this comment will run only after the data was loaded
}

或者您可以在加载完成后添加事件处理程序，如下所示：

private void LoadData()
{
    // do the loading and set the Text property of the textEdit
    TextEdit.EditValueChanged += TextEdit_EditValueChanged;
}

private void TextEdit_EditValueChanged(object sender, EventArgs e)
{
    // the code after this comment will run only after the data was loaded
}

Answer 2

使用属性

private void TextEdit_EditValueChanged(object sender, EventArgs e)
{
    if (!this.IsLoaded) return;
    // the code after this comment will run only after the data was loaded
}
