Sqldatasource onupdating method

For this you can easily create a protected method and use databind to display the username in the txt User Name Text Box.But, now the question is that how will you update the username or send the username to the database.When i debug the code, it shows that the controls datasource Id is being assigned, but when the page loads, no data is shown in the control.Can you help me out or perhaps guide me onto another path which would offer similar options.If a user is logged in as Role 'GBM' then a datasource Id of 'Sql DS_GBM' is assigned to the control, otherwise a datasource Id of 'Sql DS_AAY' is assigned to the control.

For this scenario we'll want to select the "Products" entity class we built.NET Framework 3.5 release, and which enables you to easily model relational databases using . You can use LINQ expressions to query the database with them, as well as update/insert/delete data. The simple data editing web application I'll walkthrough building in this tutorial is a basic data entry/manipulation front-end for products within a database: The application will support the following end-user features: The web application will be implemented with a clean object-oriented data model built using the LINQ to SQL ORM.Below are the first four parts of my LINQ to SQL series: control that is shipping as part of ASP. All of the business rules and business validation logic will be implemented in our data model tier - and within the UI tier or in any of the UI pages.VS 2008 includes build-in designer support to make it easy to connect up our Grid View (or any other ASP. To bind our grid above to the data model we created earlier, we can switch into design-view, select the Grid View, and then select the "New Data Source..." option within the "Choose Data Source:" drop-down: This will bring up a dialog box that lists the available datasource options to create.

Select the new "LINQ" option in the dialog box and name the resulting designer will then display the available LINQ to SQL Data Context classes that your application can use (including those in class libraries that you are referencing): We'll want to select the data model we created with the LINQ to SQL designer earlier.

Over the last few weeks I've been writing a series of blog posts that cover LINQ to SQL.

    They want to feel a connection with a female because they lack that in real life so they all run to Cam sites and literally pay for it.

I've been dating this girl for 5 years and a little over year ago I let her start webcamming from my apartment.

    Honor does not always mean doing exactly what they want, although it does many times. In this case, honoring your parents means valuing their opinions, advice, and rules.
