Rowupdating in gridview not firing
NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.We also need force databinding to occur when then page is loaded, which we’ll handle in Page_Load.The required actions for paging to work are setting the new page index, setting the Data Source, and calling Data Bind (the last two through the Bind Data method).We’ll start with binding data to the Grid View, then build up functionality from there.First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.
So for example to reference a Drop Down List within the Grid View Row, use the syntax: Basically this is quite straightforward once one knows the syntax for referencing a control within a Grid View Row. Grid View Update Event Args) Dim lbl Service Level As Drop Down List = CType(GVSupport Info.
We’ll get to how these properties are populated shortly, but first we need to go back to the Bind Data method.
The original method shown above did not implement any sorting, but now that we have a place to store the Sort Expression and Sort Direction we need to change that.
To finish up then one has to set the Sql Data Source Update Parameters to the desired values.
The syntax for doing so is: Protected Sub GVSupport Info_Row Updating(sender As Object, e As System.
