我有 TableLayoutPanel,我以编程方式将 Rows 添加到其中。用户基本上选择了一个属性,然后将其与一些控件一起显示在表格中。我想我在这里有一个普遍的理解问题,我会尝试解释它。
每行中的一个控件是一个“删除”按钮。该按钮应该删除它所在的行。我所做的是向按钮添加一个事件处理程序并设置当前行数。
deleteTalent.Click += (sender, e) => buttonClickHandler(numberOfRows);
处理程序的代码:
private void buttonClickHandler(int rowCount)
{
int count = rowCount - 1;
for (int i = count; i < (count + 5); i++)
{
balanceTable.Controls.RemoveAt(count);
}
balanceTable.RowStyles.RemoveAt(count);
balanceTable.RowCount--;
}
我看了好几个小时,到处玩。但我找不到有效的清洁解决方案。我对 C# 也很陌生
这是创建新行的完整函数:
private void addBalanceItems(ToolStripMenuItem item)
{
int numberOfRows = balanceTable.RowCount;
if (numberOfRows > 1)
{
balanceTable.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.AutoSize));
}
balanceTable.Height = numberOfRows * 45;
Steigerungsrechner rechner = new Steigerungsrechner();
string tag = item.Tag.ToString();
//change that asap :(
if (tag == "A") { rechner.column = 1; }
if (tag == "B") { rechner.column = 2; }
if (tag == "C") { rechner.column = 3; }
if (tag == "D") { rechner.column = 4; }
if (tag == "E") { rechner.column = 5; }
if (tag == "F") { rechner.column = 6; }
if (tag == "G") { rechner.column = 7; }
if (tag == "H") { rechner.column = 8; }
Label talentName = new Label();
talentName.Text = item.Text;
talentName.Height = standardHeight;
talentName.TextAlign = ContentAlignment.MiddleLeft;
talentName.AutoSize = true;
Label cost = new Label();
cost.TextChanged += (sender, e) => costChangeHandler(cost);
cost.Height = standardHeight;
cost.TextAlign = ContentAlignment.MiddleLeft;
TextBox startValue = new TextBox();
startValue.TextChanged += (sender, e) => startValueChangeHandler(rechner, startValue, cost);
startValue.Height = standardHeight;
startValue.TextAlign = HorizontalAlignment.Center;
TextBox endValue = new TextBox();
endValue.TextChanged += (sender, e) => endValueChangeHandler(rechner, endValue, cost);
endValue.Height = standardHeight;
endValue.TextAlign = HorizontalAlignment.Center;
Button deleteTalent = new Button();
deleteTalent.Text = "x";
deleteTalent.Click += (sender, e) => buttonClickHandler(numberOfRows);
deleteTalent.Height = standardHeight;
balanceTable.Controls.Add(talentName);
balanceTable.Controls.Add(startValue);
balanceTable.Controls.Add(endValue);
balanceTable.Controls.Add(cost);
balanceTable.Controls.Add(deleteTalent);
balanceTable.Visible = true;
balanceTable.RowCount++;
}
任何帮助将不胜感激!:)
