如何从占位符内的运行时表中找到控件(单选按钮) [英] how to find control(radiobutton) from runtime table inside placeholder

问题描述

大家好...
我的代码如下:

hi all...
my code goes like :

RadioButton rbpres = new RadioButton();

                       
                        rbpres.ID = "rbone" + increm;
                        rbpres.Checked = true;
                        rbpres.GroupName = "g1" + increm;

                        RadioButton rbabs = new RadioButton();
                        rbabs.ID = "rbtwo" + increm;
                        rbabs.GroupName = "g1" + increm;
                        tc1.Controls.Add(rbpres);
                        tc1.Controls.Add(rbabs);
                        tr.Cells.Add(tc1);
                        tr.Cells.Add(tc1);
 tbl.Controls.Add(tr);
placeholder1.controls.add(tbl);

当我点击按钮时
我已经写过这样的代码

when am clicking button
i have written code like this

int increm = 0;
Control myControl = FindControlRecursive(PlaceHolder1, "rbone" + increm.ToString()) ;
                    RadioButton rbpres = this.Page.FindControl("rbone" + increm) as RadioButton;
                    RadioButton rbpres1 = (RadioButton)PlaceHolder1.NamingContainer.FindControl("rbone" + increm);
increm++;
and i was try to get the id of table like
 Table tbl = this.Page.FindControl("attentbl") as Table;
and i got check with this
Table tbl = PlaceHolder1.FindControl("attentbl") as Table;
 also same result object showing null value

但是每次显示空值时我都无法获得控件，如何获取动态单选按钮的ID
有人可以帮我吗，请你
在此先感谢

but i never get the control every time it showing null value how can i get the id of dynamic radio button
can any one help me please am begging you
thanks in advance

推荐答案

试试这个代码

Hi,

try this code

if (!IsPostBack)
   {
       RadioButton rdn = new RadioButton();
       rdn.ID = "rdbtn";
       rdn.Text = "ghgfh";
       contdiv.Controls.Add(rdn);
   }
   Control d = contdiv.FindControl("rdbtn");

在上面的代码中，您必须使用表ID来搜索单选按钮控件.

而不是contdiv，您必须放置表格ID

最好的

In the above code,you''ve to use table id for searching radio button control.

instead of contdiv you''ve to place your table id

All the Best
