Updating vb control from a c program
This article scope is limited to Updating and Deleting records using Grid View and I am not using any readymade Data controls for that but manually writing all event methods.
I will be using Sql objects directly into methods to keep the example simple and straight forward.
In the same way you can put any kind of Validation controls inside Edit Item Template to validate the form element while user will click Update link.
For Page Name and Page Description field I want them to appear in the Text Box in edit view, so I have specified text property of Text Box as the field value in Edit Item Template and for Active field, I want it to appear as the Drop Down List so I have specified the Selected Value property as the value of the Active field.
The Start method of the Process object is possibly one of the most underappreciated tools available to a programmer. NET method, Start has a series of overloads, which are different sets of parameters that determine exactly what the method does. NET because you have to launch a process in a new thread if you need it to execute asynchronously.
The overloads let you specify just about any set of parameters that you might want to pass to another process when it starts. For example, if you need the components to remain active in a form where a process was launched and Wait For Exit was executed.
NET app then you can still use wy Update to update your app.
You can notice that I have kept Required Field Validator too inside the Edit Item Template as I want the textbox to be validated for empty data.
The Automatic Updater control is included with wy Build and it can be included with your applications royalty free.
It works with Visual Studio 2005 through Visual Studio 2019 and .
You may notice that the last column of the Grid View is a Delete column that let user delete the record from database, so I have placed Delete link button inside the tag and have specified on Click property as Java Script confirm return value, so that when user clicks on it he/she sees a confirmation box whether he/she really wants to delete the record.
Till now our Grid View is ready to be populated, now let’s write a method to populate the Grid View.
