           InitializeComponent();

           //lblExceeding.Visible = false;
           if (bChecked == true)

void CheckedChangedEnent(int iIndex, bool bChecked)
        {
            //pUserControl1.objList[iIndex].blnIsChecked = bChecked;

            if (iIndex == 0)
                pUserControl1.blnExceedingClick = bChecked;

            //TemplateForm tmpForm = new TemplateForm(null, null, null, null, null, null, null, null, null, true);
            TemplateForm tmpForm = new TemplateForm(bChecked);
            if (iIndex != 0)
            mDataGridView.Columns[iIndex-1].Visible = bChecked;
            //if (mCheckedListBox.Items.Count)
            //{
            //}
            //tmpForm.lblExceeding.Visible = bChecked;
            ((System.Windows.Forms.Control)(tmpForm.lblExceeding)).Visible = bChecked;
        }

推荐答案

步骤1：添加复选框并双击复选框，它将创建CheckedChanged事件。在该方法中，您可以在第2步中实现您的逻辑。



第2步：添加以下代码以显示/隐藏您的标签。

Step1: Add checkbox and double click on the checkbox it will create CheckedChanged event. Inside that method you can implement your logic in Step2.

Step2: Add below code to display/hide your label.

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
    if (this.checkBox1.Checked) 
    { 
        ((System.Windows.Forms.Control)(lblExceeding)).Visible = true;
    } 
    else 
    { 
         ((System.Windows.Forms.Control)(lblExceeding)).Visible = false;
     }
}
