Log4net could be a good idea :)

According to me, shouldn't store image into the db, instead just storing the image path.

Pls see my reply in Solution 1

Try with log4net to log everything activity on your web to db. Then, exporting all of those data to an excel file. (google search)

Try minLength property of autocomplete method to indicate how many characters entered then searching. Maybe the performance will be reduced.

When someone clicking to your video link, firstly you need to check user's permissions. If this user is paid user, then redirecting/opening the video. Else, redirecting or show a message to as their don't have permission to view this content...

Dataset dsPwd always null, pls recheck your code and make sure this dataset has data before you can proceed.

Instead of using three dropdown lists, why do you not use calendar control (.net control) or jquery datetimepicker?

Just right click on your webservice file, then click to View In browser(if you run at local)

Make sure the local code and production code are the same. Maybe you're missing some code. Recheck.

You can try with the below:
- Select your gridview
- Press F4 to open Properties box
- Locate PageSize property, then put the number of records you want to display in per page.

Have you tried as:
- Select your chart
- In the properties box, locating Size property and then set chart's width?

You can use both of DataList and Repeater to do that.
So, after looking at your code, it seems work fine. However, pls try to remove some code and use below code for your testing.

<asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal">
<itemtemplate>
//Code here
</itemtemplate>

Because two tables having the relationship together via userId column. So, make sure before you inserting data to FileInfo table then the userId must be already existed inside UserInfo table.

To do that you can use ajax or update panel. Try to google searching for more detail.

In Page_Load event of the page, firstly you need to get the expire date from your db. Once you got it, then comparing the current date with it.
If the current date is greater than expire date, then hide that link or replace current link by a new link.

Try to add the below code before you do the while loop.
if (dr.HasRows)
{
while (dr.Read() == true)
.........................
}

Before running your asp.net code then your service need to be started.

I think before you inserting the new data then you should have a step to check the existence of that data. If it is already in db, then showing a message. If not, then inserting.
