Hi all,

I am stuck in transfering some variables from one page to the other.

The whole picture is like this , I am intending to write code for the disscussion board.

When the user clicks any topic the user must be redirected to the details/reply page Along with the topic Id (So that the details must be fetched from the DB against that Topic ID).

The problem is that the list of topics is displayed in the datagtrid under "Topic Name" coulmn which is hyperlink coulmn. ON clicking the desired Topic I want to send "TopicId" variable.

I can send and receive the "Topic name" variable easily, as it is hyperlink and i can access it using query string on the other page.

But I need to send "TopicId" when there is a click on the "TopicName" coulmn. Also the TopicId is not visible in the datagrid, but it is there in my DB as PK.

Regards

There are several ways of doing this.

Method 1:

While Designing the grid, You can add a Hyperlink column and mention the url in the sql statemetnt. You need to construct the SQL statement in such a way that it also contains a column containing the URL which you want to do the redirect. You can also add the TopicID as the query string.
     Select TopicID, TopicName, '../Topics/TopicDetails.aspx?' + Cast(TopicID as Varchar) As URL From Topics

This can be the query for your grid and when you populate the grid, you add this url as the url of the hyperlink column.

Method 2:

You can add a template column and inside that template column add a linkbutton adn pass the TopicID as the CommandArgument to the OnCommand event of the linkbutton. In the OnCommand event, you can add code to redirect to the desired url with the TopicID as the querystring.
