Row updating in gridview in asp net c

21 Nov

To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.

A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.

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").

before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value).

Every one can use it to compare the new value with old ones.

A Grid View Update Event Args object is passed to the event-handling method, which allows you to determine the index of the current row and to indicate that the update operation should be canceled.

To cancel the update operation, set the Cancel property of the Grid View Update Event Args object to true.

In the code below I have shown how you can extract the new values from the textboxes inside the Grid View.

Once, you got the values you just need to send them to the database.
