将alloworting设置为true时，网格的Cell.Text属性为空白 [英] Cell.Text property of grid is blank when allowsorting is set to true

问题描述

在下面的代码中，如果我设置了grd.AllowSorting = true，则代码块:

Hi,
In the Below Code, If I set grd.AllowSorting = true then the code Block:

if (cell.Text == "Login")
{
  cell.Text = "TUSHAR";
}

未执行.

如果我注释代码grd.AllowSorting = true
在这种情况下，代码

is not executed.

And If I comment the code grd.AllowSorting = true
in that case the code

if (cell.Text == "Login")
{
  cell.Text = "TUSHAR";
}

被执行

如果我将alloworting设置为true，那么任何人都可以说出cell.Text属性为何为空白将很有帮助.

is executed

It would be helpful if any one can tell why the cell.Text property is comming blank if i set allowsorting equal to true.

嗨
您可以在客户端添加新的div控件.

hi
you can add new div control in client side.

将GridView控件添加到服务器端的div控件之后.
divControl.Controls.Add(grd);

after your GridView control add to div control in server side.
divControl.Controls.Add(grd);
