Row updating event in asp net Sex on webcam without card credit


Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").For a while now I’m trying to figure out why my method, triggered by the Grid View.Row Updating event, doesn’t work as all samples say it should do.

Image button in popup header is used as Cancel Control ID but we also have a cancel button in our modal popup and here is the code to close the modal popup by cancel button without postback: If you can see we used if not is postback because we don’t want to load record on every postback but only for the first time, on page load.

event is raised when a row's Update button is clicked, but before the Grid View control updates the row.

This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.

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.

Check out what I’m trying to do, maybe you can help?
