Rowupdating in gridview in asp net example
I've searched in here: can't find any examples that make sense to me. It may be close, but I've seen parts of it done other ways and I don't know what is right or the best way.
I could really use a complete example of a simple Grid View, markup and code behind both, that included all the common things you need a Grid View to do: Create a Data Table or Data Set, Fill the Grid View, Edit, Cancel Editing, Updating , Sorting, Paging. ' str Query = "Select * from Employer where " & ddl Search By.
Bind Data could be called in Page Index Changing, but to show that it the event is raised, we’ve handled that in Page Index Changed.
The important point is not which of these two events call Bind Data, but one of them must or the Grid View will not be updated. When bound using a Data Source ID, the Grid View internally tracks the current Sort Expression and Sort Direction, and those are available through properties with the same names.
The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.
The Grid View 'Grid View1' fired event Sorting which wasn't handled.
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).
In addition to that, we’re resetting the Edit Index and Selected Index when the page is changed to avoid cases, for example, where you change pages and are suddenly editing a different item.
NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.
We’ll revisit this method when we implement the sorting functionality.
We also need force databinding to occur when then page is loaded, which we’ll handle in Page_Load.
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.
After specifying the query, we add the appropriate sorting. When you bind a Grid View through a Data Source ID, the Grid View will update this value since it is internally tracking the sort expression, so it knows when to switch between ascending and descending.
The way we’ll accomplish this is to create two properties that store those values in View State.
