我目前正在尝试TableLayoutPanel
通过以下方法填充 a:
private int _rowCount;
public void InitPaths()
{
int c = 1;
int a = 1;
while (a < _PathRows.Length - 1)
{
var label = new Label();
//
// Label - Format.
//
label.Dock = DockStyle.Fill;
label.AutoSize = false;
label.Text = _pfadZeilen[a];
label.TextAlign = System.Drawing.ContentAlignment.MiddleLeft;
label.Size = new System.Drawing.Size(22, 13);
label.BackColor = System.Drawing.Color.Transparent;
TableLayoutP.Controls.Add(label, 3, c);
//Checkboxen Einfügen
var cbox = new CheckBox();
//
//Checkbox Format.
cbox.Anchor = System.Windows.Forms.AnchorStyles.None;
cbox.AutoSize = true;
cbox.CheckAlign = System.Drawing.ContentAlignment.MiddleCenter;
cbox.Name = "checkBoxPfad" + a;
cbox.Size = new System.Drawing.Size(15, 14);
cbox.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
cbox.UseVisualStyleBackColor = true;
TableLayoutP.Controls.Add(cbox, 0, c);
a++;
c++;
}
this._rowCount = BibTable.GetRowHeights().Length; // which seems to be Holding the value only within the method
}
然后通过以下方法删除Action上的所有行:
public void RemoveRows()
{
for (int row = _rowCount; row >= 0; row--)
{
BibTable.RowStyles.RemoveAt(row);
BibTable.RowCount--;
}
}
现在的问题是,如果我尝试在TableLayoutP
初始化所有行的方法之外做任何事情,它会告诉我:
对象引用未设置为对象的实例。
我能做些什么?有没有办法在方法中获取方法(我意识到在输入它时听起来多么愚蠢)或任何其他方式来处理这种情况?
