图像ü可以看到这是我的GridView，其中的复选框给出的数据检查了我的复选框。现在更新时，当我执行我的filladd（）函数复选框不检查，即使他们是真的所以请帮助它.. !!

private void filladd(int p) 
{ 
    DataTable dt = new DataTable(); 
    dt = b.get_subpaf(p);//MJ SP CHANGE 
    if (dt.Rows.Count > 0) 
    {   
     DataExtensionList.DataSource = dt; 
     DataExtensionList.DataBind(); 
     ViewState["ExtensionId"] = dt.Rows.Count; 
     ExtensionBind(); 
    } 
} 

Answer 1

<asp:CheckBox ID="chkport" runat="server" Checked='<%# DataBinder.Eval (Container.DataItem,"Port_Trikon").ToString()!="0"?true:false %>' /> 

确保数据库或者是bit数据类型或只返回1,0串

Answer 2

我得到了上面的回答只是更换旧的被问的问题这个功能

private void filladd(int p) 
{ 
    DataTable dt = new DataTable(); 
    dt = b.get_subpaf(p);//MJ SP CHANGE 
    if (dt.Rows.Count > 0) 
    { 

     DataExtensionList.DataSource = dt; 
     DataExtensionList.DataBind(); 
     foreach (GridViewRow it1 in DataExtensionList.Rows) 
     { 
      CheckBox chk = (CheckBox)it1.FindControl("chkcata"); 
      CheckBox chk1 = (CheckBox)it1.FindControl("chkport"); 
      CheckBox chk2 = (CheckBox)it1.FindControl("chkwhilepages"); 
      if (chk.Text == "True") 
      { 
       chk.Checked = true; 
      } 
      if (chk1.Text == "True") 
      { 
       chk1.Checked = true; 
      } 
      if (chk2.Text == "True") 
      { 
       chk2.Checked = true; 
      } 
     } 
    } 
}
