Pass Value From One Web Page To Another in Asp.Net

Suppose there is a scenario in which you want when you click on some text then associated value should pass to another page and with the help of this associated value you can do anything. That link my be simply in paragraph or in Grid View or in Data list.
There may be many methods to do it and I hope one of them called 'Session' be in you knowledge. But doing this with help of session is not considered good so here we will use other technique as well..
Suppose you have Page 'a.aspx' and other page 'b.aspx' you want to pass value from one to another then on first page write this code but before this suppose you have a link button on click of this associated value will pass to 'b.aspx'.
code on click event of link button in 'a.aspx'

Response.Redirect("b.aspx?value=" + here you should write variable of reference variable);
Response.Redirect("b.aspx");

on the page 'b.aspx' of page load event write following code (you can take this value in variable in the form of string.

string passedvalue= Request.QueryString["value"];
here value will carry the assigned value from one page to another. But if you are using Grid View and have link and want to display associated data on other page. Then you will have to use OnRowCommand="shashi_RowCommand" event of Grid View and corresponding command name property of link button so that various link button associated with Grid View can perform various tasks.
In my example.

here i have two link buttons in my grid view that's why used two command name so that they can perform various task associated with them. You will have to give command name in link button. see this image.

DTS package conversion in SSIS to use in SQL 2012 and SQL 2016

In my company my team decided to migrate whole SQL 2008 to brand new SQL 2016 in Azure VMs. This was a good idea as we should always be up to date in terms of technology. We did migration all SQL 2008 to SQL 2016 without any problem but suddenly we saw we need to migrate warehouse as well and it was containing very complex DTS package almost 50 in number and we have very less time to finish this task. We first decided to do following things: Upgrade DTS in SSIS with wizard available in SQL 2008 But this was not helpful because if you have some VB script written in DTS and it enables or disables any step then it will not work in SSIS because enabling and disabling is not allowed in SSIS. YOu will have to manually correct all these code. So we tried this and dropped this idea. Manually Convert whole DTS in SSIS: This was blunder for us as it was going to take many months of re creation and testing so tried this and dropped this idea as well because we got a very motivati
