Updating grid view Secret sites for sex chat nepali bhutnese

In this article, I am going to explain how to manipulate data using Grid View control.

After that again, I am doing the same thing that I had done in Cancel Record method, I mean setting Edit Index property of the Grid View to -1 and rebinding the data again by calling Bind Data() method.

When Delete link of the Grid View will be clicked, it will confirm the user whether they really want to Delete the record, if they will click OK, it will fire On Row Deleting event of the Grid View that will call Delete Record method.

I am not able to get the changed values that i enter in the grid view .

My best effort got me the value that was in gridview before editing or changing.

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").

In this method again, I am getting the primary key value using Data Keys property of the Grid View and using it to delete the records from the database.

After successfully deleting records, again I am calling Bind Data() method to rebind the Grid View.

You can notice that I have kept Required Field Validator too inside the Edit Item Template as I want the textbox to be validated for empty data.

In the same way you can put any kind of Validation controls inside Edit Item Template to validate the form element while user will click Update link.

Please note that when you will not bind the data again, Grid View will not change in edit mode.
