asp.net - How to preserve value of dynamic created gridview column -

-

I have made all the gridview columns dynamic and the column also exists checkbox. The problem with Gridview does not preserve this dynamic-built column value. For example if I have selected some line through the checkbox column and clicked on the button to get all the selected row IDs, the page becomes empty as the grid is not empty with the data value.

Any help would be highly appreciated.

Thanks, Alvin

This probably happens when you are creating dynamic columns Are there.

If the column is created in the page_load event, or after the page event process, the viewstate will not be able to populate your columns on a postback.

If possible, try to create your dynamic columns in the Page_Init event, this will allow the viewsto to properly load the column.

I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
