Don't worry. Not everyone knows it...

Many of you might have come across an issue of Auto incrementing while working with database products. Truly speaking, recently I also came across one silly problem and thought of sharing it here. Imagine that at some point of time, you might want to send your new data to a back-end database. If your application supplies the auto-increment values, then what will the database do? what if application receives duplicate values from different client applications? The answer is that these auto-increment values are never sent to the database because the auto-increment column in the database table will provide a value whenever a new row is added. After each new row is added, the back-end database table generates a new-increment number and then your application will query the database to get the newly created number. Your application will then update its primary key number to the values that came from the database. This means that all the foreign key references will need t...

So, why can't we use this StringFormat for our binding too. If you want to change the above code to incorporate StringFormat , then it will something look like: <WrapPanel>         <TextBlock>     ...

So, to deal with this Microsoft provide us with a Viewbox control, in which user can set the resizing aspects as per the need and requirement. So, this article focuses mainly on the properties provided by Viewbox control with proper sample code and output.
