Dear All,
I would like to ask you all about my problem in C# code.
I have a default.aspx page that have some button and one Place holder to store usercontrol.
For first load place holder is empty, but if i click one of button it will store user control inside the placeholder, than if i click another button it will change content of place holder.
The problem is, the usercontrol (upload.ascx) show one datagrid that have some page. When i change the page of the data grid, the placeholder will empty and usercontrol (upload.ascx) is removed. What should i do to solve this problem. Thanks
