RadioButton rb =(RadioButton)grdLanguagedesc.Rows [i] .FindControl(&"RowSelector& quot;);;
如果(rb.Checked == true)
{
//Page.ClientScript.RegisterStartupScript(this.GetType()，clientScript，返回Confirm(``确定要删除此记录吗?'');, true);
//ScriptManager.RegisterStartupScript(this、this.GetType()、clientScript、confirm_delete();、true);
//Page.ClientScript.RegisterStartupScript(this.GetType()，clientScript，javascript:if(！confirm(``您是否希望完成此订单?''))返回false;);

推荐答案

为按钮添加OnClientClick javascript函数和显示确认按钮并仅在用户确认后返回true.

Add OnClientClick javascript function for the button and show the confirm button and return true only if user confirmed it.

1.为Grid itemdatabound/rowdatabound事件编写一个事件处理程序.
2.在该事件处理程序内，使用FindControl方法找到每个单选按钮.
3.在单选按钮控件的属性集合中添加一个javascript函数.别忘了写"return"，如下所示

1. Write an event handler for the Grid itemdatabound/rowdatabound event.
2. Inside that eventhandler, find each radio button using FindControl method.
3. add an javascript function in attributes collection of radion button control. Dont forget to write "return" as follows

RadioButton rd = FindControl...

rd.attributes.add("onclick","return ShowAlert(this.id)");

4.编写如下的javascript函数ShowAlert()

4. Write a javascript function ShowAlert() as follows

function ShowAlert()
{
   var response = Confirm("Want to proceed?")
   if(response)
   return true;
    else
   return false;
}
