add this line in aspx page link button visible=<%#convert.toboolean(Eval("Enable"))%> and take extra enable column in datatable and give this value to behalf of your condition if (diff > 7) dr["enable"]=false and bind this datatable to repeater

Solution 1

try that

C#

int diff = userdate.Day - DateTime.Now.Day;//this is the difference in days if you want another difference
                                                   //ex in mon monthes use userdate.Month and so on
            if (diff > 7)
            {
                // Do something    linkbutton.Visible = true;
            }

hi friend thnx for reply me i was using already this but when i am running my code then error is ocuuring
Object reference not set to an instance of an object on this line
linkbutton.Visible = true;

ok man this error means that your object is created but not instantiated (your object is null ex: Car blackCar;) in this case blackCar is null and you cant use any property in Class Car if you can send me your piece of code to know where is the error or tell me at which line of code regards

look man are you sure you create the linkbutton in a correct way (linkbutton linkbutton = new linkbutton();) and i prefer to create it in the aspx page ex:
<asp:LinkButton runat="server" ID="linkbutton" Text="blablabla">
waiting your reply
