單擊按鈕時禁用Itemscontrol組件
[英]Disable Itemscontrol components on button click
問題描述
我正在通過mvvm學習wpf。
我的應用程序由以下邏輯組成。
該窗體具有一個按鈕，只要單擊該按鈕，該按鈕就會從Itemcontrol中水平添加選定的組件，例如文本框，組合框和富文本框，以及一個按鈕。
單擊添加按鈕時，指定的組件集將動態添加到行信息中。
2）按添加信息按鈕后，數據將插入表中。
3）問題是單擊添加信息按鈕后 ，itemscontrol中的組件應為只讀。 到目前為止，這是我一直在努力的地方。
Model.cs:
public class textboxModel
{
public string Text { get; set; }
public string lblText { get; set; }
public string isactive { get; set; }
public bool txtboxreadonly { get; set; }
}
public class ButtonDataModel
{
public string Content { get; set; }
public ICommand Command { get; set; }
public string column { get; set; }
public string isactive { get; set; }
public bool buttreadonly { get; set; }
}
ViewModel.cs：
public class viewmodel : notifyproperties
{
public Relaycommand Status { get; set; }
public Relaycommand AddCommand { get; set; }
public labelconversionOnPauseButtonclick pauseclick = new labelconversionOnPauseButtonclick();
public auditinformation auditid = new auditinformation();
public ButtonDataModel bdm = new ButtonDataModel();
public auditinformation adt
{
get { return auditid; }
set
{
if (value != auditid)
{
auditid = value;
OnPropertyChanged("adt");
}
}
}
public labelconversionOnPauseButtonclick res
{
get { return pauseclick; }
set
{
if (value != pauseclick)
{
pauseclick = value;
OnPropertyChanged("res");
}
}
}
public viewmodel()
{
Status = new Relaycommand(pauseclick.Statusdata);
AddCommand = new Relaycommand(o => auditid.addcommand());
}
}

public Relaycommand Command { get; set; }
private string _lines;
public string Lines

}

public void addcommand()
{
int num= 1;
for (int i = 0; i < num; i++)
{
MyDatatxtbox.Add(new textboxModel
{
isactive = "1",
});
MyData.Add(new ButtonDataModel
{
Command = new Relaycommand(o => search()),
Content = "Add info",
isactive = "1",
});
}
}
public void search( )
{
var asss = MyDatatxtbox.Where(a=> a.isactive == "1").Select(a => a.Text);
var itemstoremove = MyDatatxtbox.Where(i => i.isactive == "1").ToList();
foreach (var s in asss)
{
foreach (var a in itemstoremove)
{
if (a.isactive == "1")
{
MessageBox.Show(s);
buttreadonly = true;

骯臟的方法是在ViewModel中添加“全局” bool屬性，並將其綁定到Controls IsEnabled / ReadOnly屬性。
