Im pretty new to ASP.net but am getting there slowly but surely! Its definitely growing on me.
The problem im looking at at the moment is i have a gridview displaying data from my SQL database, which works fine. I have enabled the selection option on the gridview which has placed a select link next to each row. Perfect.
What I am looking to do is be able to click the select button, and have the details from each column on that row go into variables when the page is posted back. I will then write these back to a different table in the database later on.
I see that when i click the link it is posting back the number of the row i have selected, but how do i use this to get the data from each column out of the gridview?
have trouble to add delete column to gridview when using specific query.I have PK set up at the table, I need add specific query to display dataat gridview:
SELECT [PID], [GID], [TID], [SID], [NEWSID] FROM [TableOne] WHERE ([NAME] = ?)
After builder this query, I click advanced button. However, generate insert, update, and delete Statements is not enabled.
I am trying to keep a button disabled unless a row in my gridview has been selected. If I just keep the button disabled, I cannot ever get it re-enabled.I am assuming I need some javascript to enable it when a row is selected.

Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)

I have a set of 4 buttons which part of a gridview template and I load the gridview on page_load. The datasource for the gridview comes via my controller as I am using Microsoft's Model View Controller design pattern. I set 4 public properties for each of the 4 buttons, which I can access in my controller class/method. However, when I call the method for the gridview, which sets the datasource for it on page_load, I get an error message when I try to set the enable to false. It says "Object not set to instance of object". The objective I am trying to do here is a check on a returned value, which I can achieve, and based on the return of the value that is returned, to either set the button enable to true or to false.
Unfortunately, I am getting this Object not set to instance of object error message, and I do not know how to resolve it.
