Gridview rowupdating example asp net
Row Updating event, doesn’t work as all samples say it should do.
All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.
The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set.
Which means I won’t make my 70% code reduction Microsoft has always promised me.
You can see the C# code below will give the row number whatever you are editing by New Edit Index property.
So Grid View will put the appropriate row into the Edit Mode by assigning row number to its Edit Index property. You can follow any responses to this entry through the RSS 2.0 feed.
If we use proper command names for the buttons like “EDIT”, “DELETE”, “UPDATE”, “CANCEL” these will also trigger the appropriate Grid View Events.
First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.
To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.
In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.
Row Deleting – Occurs when a row's Delete button is clicked, but before the Grid View control deletes the row.
