獲取網格單元格並清除其中的所有控件

Question

我有一個有兩列和多行的網格，每個單元格包含多個控件。在這些控件中，我有一個按鈕，當按下它時，應刪除當前網格單元格中的所有控件。我如何獲得我的按鈕所在的網格單元格的索引以及如何刪除此單元格中的所有控件？

Answer 1

這是否適合您？你需要添加一個using聲明System.Linq

//get the row and column of the button that was pressed. 
var row = (int)myButton.GetValue(Grid.RowProperty); 
var col = (int)myButton.GetValue(Grid.ColumnProperty); 

//go through each child in the grid. 
foreach (var uiElement in myGrid.Children) 
{ //if the row and col match, then delete the item. 
    if (uiElement.GetValue(Grid.ColumnProperty) == col && uiElement.GetValue(Grid.RowProperty) == row) 
      myGrid.Children.Remove(uiElement); 
} 

Answer 2

使用LINQ和擴展以前的答案，注意ToList（），這樣你就可以立即刪除元素

//get the row and column of the button that was pressed. 
var row = (int)myButton.GetValue(Grid.RowProperty); 
var col = (int)myButton.GetValue(Grid.ColumnProperty); 

//go through each child in the grid. 
//if the row and col match, then delete the item. 
foreach (var uiElement in myGrid.Children.Where(uiElement => (int)uiElement.GetValue(Grid.ColumnProperty) == col && (int)uiElement.GetValue(Grid.RowProperty) == row).ToList()) 
{ 
    myGrid.Children.Remove(uiElement); 
}
