How to clear WPF Grid contents?
提问by Muad'Dib
I want to clear/remove ALL the contents of a Grid including RowDefinitions, how can I do that?
我想清除/删除网格的所有内容，包括 RowDefinitions，我该怎么做？
回答by Muad'Dib
myGrid.Children.Clear()will remove all child controls nested in the grid.
myGrid.RowDefinitions.Clear()will remove all row definitions.
myGrid.ColumnDefinitions.Clear()will remove all column definitions.
myGrid.Children.Clear()将删除嵌套在网格中的所有子控件。
myGrid.RowDefinitions.Clear()将删除所有行定义。
myGrid.ColumnDefinitions.Clear()将删除所有列定义。
for the sake of completness, you can also add/remove single items through the add/remove methods of the appropriate collections. myGrid.Childrenfor controls, myGrid.RowDefinitionsfor row definitions, and myGrid.ColumnDefinitionsfor the columns.
为了完整起见，您还可以通过相应集合的添加/删除方法添加/删除单个项目。 myGrid.Children用于控件、myGrid.RowDefinitions行定义和myGrid.ColumnDefinitions列。

try to loop into your container control(Example a Grid) and in this loop check the type of the control like this :
尝试循环到您的容器控件（例如网格）并在此循环中检查控件的类型，如下所示：
foreach(DependencyObject c in YourContainer.Children)
{
//If you only want to modify TextBoxes
if(c.GetType().ToString() == "System.Windows.Controls.TextBox")
{
//Erase Text property of all TextBoxes in my Grid Control
((TextBox)c).Text = "";
}
}
