问题描述

public partial class Table : System.Web.UI.Page
    {
        
        
        protected void Page_Load(object sender, EventArgs e)
        {
            
        }
 
        protected void BtnAdd_Click(object sender, EventArgs e)
        {                 
            int r_count = TblPassenger.Rows.Count;
            int c_count = TblPassengerRow.Cells.Count;
            Label1.Text += "Actual Rows:" + TblPassenger.Rows.Count.ToString();
            AddNewRow(r_count,c_count);
            
        }
 
        private void AddNewRow(int r_count, int c_count)
        {
            
            for (int i = r_count - 1; i < r_count; i++)
            {
                TableRow TbRow = new TableRow();
                TblPassenger.Rows.Add(TbRow);
                for (int j = 0; j < c_count; j++)
                {
                    TableCell TbCell = new TableCell();
                    if (j == 0)
                    {
                        Label LblSNo = new Label();
                        LblSNo.ID = "LblSNo" + i + "" + j;
                        TbCell.Controls.Add(LblSNo);
                    }
                    else
                    {
                        TbRow.Cells.Add(TbCell);
                        TextBox Txt = new TextBox();
                        Txt.ID = "TxtFirstName" + i + "" + j;
                        TbCell.Controls.Add(Txt);
                    }
                    TbRow.Cells.Add(TbCell);
                }
                this.TblPassenger.Controls.Add(TbRow);
                
            }
            this.frmTable.Controls.Add(TblPassenger);
            Label1.Text += "after adding Rows:" + TblPassenger.Rows.Count.ToString();
            r_count = 0;
            c_count = 0;
        }

输出我GOT：

首先添加Click事件，它添加了在页脚行之后显示的控件。

如果我再次点击它会替换最后一行，即新添加的控件

< br $> b $ b

请帮助我，我需要在下一阶段添加动态添加控件的事件



我无法提供此处的输出图像

推荐答案

TblPassenger和TblPassengerRow是动态的还是静态的？

似乎问题在于计算。

TblPassenger and TblPassengerRow is dynamic or static?
seems the problem is in taking the count.
