如何在动态添加的控件中存储某些变量值

Question

我有一个通过编程添加的按钮，我想用每个按钮存储特定的唯一信息。我已经保存了名称和文本，但有没有办法存储另一个字符串以便以后访问。下面是我的按钮和它的点击事件的代码。

for (int i = bankaccountsDatagridview.Rows.Count - 1; i >= 0; i--)
{
string buttonName = "individualDepartmentBtn-" + i;
FontAwesome.Sharp.IconButton individualDepartmentBtn = new FontAwesome.Sharp.IconButton();
individualDepartmentBtn.BackColor = System.Drawing.Color.White;
individualDepartmentBtn.Cursor = System.Windows.Forms.Cursors.Hand;
individualDepartmentBtn.Dock = System.Windows.Forms.DockStyle.Top;
individualDepartmentBtn.FlatAppearance.BorderSize = 0;
individualDepartmentBtn.FlatAppearance.MouseDownBackColor = System.Drawing.Color.Silver;
individualDepartmentBtn.FlatAppearance.MouseOverBackColor = System.Drawing.Color.FromArgb(((int)(((byte)(224)))), ((int)(((byte)(224)))), ((int)(((byte)(224)))));
individualDepartmentBtn.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
individualDepartmentBtn.Flip = FontAwesome.Sharp.FlipOrientation.Normal;
individualDepartmentBtn.Font = new System.Drawing.Font("Roboto", 11.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
individualDepartmentBtn.ForeColor = System.Drawing.Color.DimGray;
individualDepartmentBtn.IconChar = FontAwesome.Sharp.IconChar.None;
individualDepartmentBtn.IconColor = System.Drawing.Color.DimGray;
individualDepartmentBtn.IconSize = 25;
individualDepartmentBtn.ImageAlign = System.Drawing.ContentAlignment.MiddleLeft;
individualDepartmentBtn.Margin = new System.Windows.Forms.Padding(10);
individualDepartmentBtn.Padding = new System.Windows.Forms.Padding(30, 0, 0, 0);
individualDepartmentBtn.Name = bankaccountsDatagridview.Rows[i].Cells[1].Value.ToString();
individualDepartmentBtn.Rotation = 0D;
individualDepartmentBtn.Size = new System.Drawing.Size(192, 30);
individualDepartmentBtn.TabIndex = 1;
individualDepartmentBtn.Text = bankaccountsDatagridview.Rows[i].Cells[1].Value.ToString();
individualDepartmentBtn.TextAlign = System.Drawing.ContentAlignment.MiddleLeft;
individualDepartmentBtn.UseVisualStyleBackColor = false;
navigationPanel.Controls.Add(individualDepartmentBtn);
individualDepartmentBtn.MouseDown += new System.Windows.Forms.MouseEventHandler(individualBankBtnDown);
}

点击事件：

private void individualBankBtnDown(object sender, MouseEventArgs e)
{
bankTitle = ((FontAwesome.Sharp.IconButton)sender).Name.ToString();
}

Answer 1

您可以使用Tag属性。例如：

individualDepartmentBtn.Tag = "My String";

您可以在Tag中存储任何对象，而不仅仅是字符串。

请注意，您还可以使用var关键字和对象初始值设定项来提高代码的可读性：

var individualDepartmentBtn = new FontAwesome.Sharp.IconButton
{
BackColor = System.Drawing.Color.White,
Cursor = System.Windows.Forms.Cursors.Hand,
Dock = System.Windows.Forms.DockStyle.Top,
...
};
