Asp updating access check box - Free Online

In the following tutorial I will show you how you can use Check Box in the Grid View which not only display the current status of the record but also update the record status in the database.protected void Page_Load(object sender, Event Args e){ if (! Is Post Back) { Load Data(); }}private void Load Data(){ string constr = @"Server=.\SQLEXPRESS; Database=Test DB;uid=waqas;pwd=sql;"; string query = @"SELECT Category ID, Category Name, Approved FROM Categories"; Sql Data Adapter da = new Sql Data Adapter(query, constr); Data Table table = new Data Table(); da. You should store your database connection string in web.config file. You can also call stored procedure in the above code if you don’t want to write SQL Query directly in your code or you can also call your Data Access Layer component to retrieve Categories Table from database. NET source will show you how you can use Template Field in the Grid View to display Check Box with the current status of the Category in the database.

I am also setting the Text Property of the Check Box Approved or Not Approved according to the state of Approved Column in database. To provide user option to update the status of any Category from the Check Box I am also setting Auto Post Back Property to true and adding Event Handler chk Status_On Checked Changed to handle On Checked Changed event. Checked; string constr = @"Server=.\SQLEXPRESS; Database=Test DB;uid=waqas;pwd=sql;"; string query = "UPDATE Categories SET Approved = @Approved WHERE Category ID = @Category ID"; Sql Connection con = new Sql Connection(constr); Sql Command com = new Sql Command(query, con); com. Every time user will check or uncheck the Check Box this event will update the status of Approved Column in the Database. public void chk Status_On Checked Changed(object sender, Event Args e){ Check Box chk Status = (Check Box)sender; Grid View Row row = (Grid View Row)chk Status. Close(); Load Data();} In the above code, first four lines are doing the main job. I had already written a similar script sometime back to Check/Uncheck all Items in an ASP. Using portions of that script, here’s how to Check Un Check all Check Boxes in an ASP. ASPX Page (with j Query script)The j Query code shown above finds all elements of the checkbox type inside the Grid View and sets the ‘checked’ value of all items in it to true or false based on the checked value of the ‘Chk All’ checkbox.

I am getting the reference of Check Box by type casting the sender parameter of the Event Handler.

One of the most common control developers uses in the Grid View is Check Box control and if you are creating Administration Panel of any ASP. To get the Category ID I am getting reference of the entire Grid View Row object. NET code to execute the Update Query in Database using Sql Connection and Sql Command object.

NET Application you may be required to handle checkbox event to update any back end database table.

One Typical example is to Enable/Disable status of any record in the database table using the Check Box in the Grid View. Data Bind();} Please keep in mind that I put connection string directly in the code just for the demonstration.
