Gridview1 rowupdating old values blind dating 2016 avi news

So now we could flag a page as being in Edit Mode and bail out of check Exit if it was (even if the apge was flagged as being dirty).

But we were not out of the wood quite yet – we still needed to wire the new functions into the rest of the code.

Most Web Developers have come across this problem at one time or another, how do I stop someone navigating away from a page if they have not saved any changes they have made?

If they make changes to the data fields and click OK then the flags are reset accordingly.

Now we just need to handle the situation where the user clicks on the Cancel button of a row in Edit mode. It may not be the only, or the best way but it solved the problem that we encountered.

For those who do not know on how to generate Events in Grid View you can follow these steps below: I have a project that I coppied the above code into.

When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values.

My first approach was to set the dirty status of the page when any row was actually updated, i.e.

when the user clicked on the OK button of the Edit Row.Adding the following code to the Row Cancelling Edit event sorts that out: So there you have it, one method of utilising Dirty Checking in ASP.

Contol[0])Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System. We needed to add the ‘onclick’ attribute to each Edit button in the Grid View to flag the page as being in Edit Mode.The simplest way of doing this is from within the Row Created event: When the row has been updated we need to clear the Edit mode flag and set the pages Dirty state to True.This could easily be caught in the Row Updated event and seemed a logical choice and initially seemed to work as expected – until one of those damn tester people got hold of it.
