Interactive Table for runtime database updation in asp.net

Hi all,
I have to design a page in which a list of entries from a database are to be displayed as a table(either normal html table or maybe gridview or something.) with some checkboxes in it. The user should be able to select some options from these checkboxes and the selected value shud be updated to the database once when it is posted. I'm new to asp.net and c#.

As an example.
Consider an attendance mgmt system wherein the candidates are listed in a table with checkboxes that enables a person to select whether a person is present or absent and the person clicks an update button which posts that attendance data to a database.

Thanks in advance

Hi,

Follow the steps below...

1. Add an item template columns with a checkbox to gridview.

2. Enable AutoPostBack of CheckBox

3. Handle the OnCheckedChangedEvent for Checkbox.

in the function write the following code.

CheckBox objCheck=sender as CheckBox;

GridViewRow objRow=objCheck.NamingContainer as GridViewRow;

GridViewRow objSelectedRow=GridView1.Rows[objRow.Index];

// Here you can extract the values from the cells of the Selected Row.

string strName=objSelectedRow.Cells[1]; // assuming that Cell[1] contains the name

// The Update Query can be then fired to update the data.
