I am new to the wonderful world of asp.net gridviews. As of now, my gridview would have several rows each with a edit and update button. When I click edit, the editable cells turn into textboxes and can be successfully updated. However, if I am in edit mode in one row, and I click an update button in another row, an error will fire.
So my question is, how could I validate that the current row finished editing? Ive been searching google and I understand how to make field templates, assign a control, and can validate a certain cell. But I am not sure of a way to force someone to finish editing before causing that error. Thanks in advance!
From comments:
Why do you provide an update button when the row is not in edit mode?
You could set AutoGenerateEditButton to true. Then update + cancel buttons are shown when edit was clicked.

I am working on a MVC application. My requirement is as below.
Add/Edit/ Delete functionality (done this using editor template). Done
Display read-only information on double click of row. - Need Solution.
Delete selected row in button click
Description: The user should be able to view the details of a row by double clicking the row. Double clicking the row should display the details in read-only mode.
Then the other problem is how can i be able to select a row and delete it by button click.
Please let me know how I can achieve this functionality.
Usually something like is achieved with javascript/jQuery.
You would bring down the read-only data when the page is first loaded but hidden from view. Then set it up so that when you double click a row the extra information is displayed through modifying the CSS display value.
It would be equally as easy to show this information in another window - or wherever else you desire.
For more information take a look at the jQuery website
I am creating a web page using C# ASP.NET and Visual Studio 2008. I would like to create a dataentry form on my web page using GridView. Whenever a user may, he/she can edit the record on GridView (I have did this using edit, update, cancel option) but I would like to place another button in GridView named "Close" by which user can make that particular record "Non-editable". After clicking on close button on Gridview that record get locked and no body can edit that record in future.
Can anybody help me?
Maybe you can do that by adding a column to your table in your database. If the close button was clicked in your gridview, update the data in the database and make it closed so that it cannot be edit in your gridview.
Hope this gives you idea.
I have an application that has a datagridview in it obviously enough, and I add data to it programatically like so:
dataGridView1.Rows.Add(string[]);
Before I add any objects to the dataGridView I can edit the cells by double clicking, hitting enter or f2. After data has been added into the rows however, I can no longer edit any of the values. I have tried toggling the "Read Only" attribute from true to false, and also tried to mess with:
dataGridview1.EditMode ....
I don't know how to make the edit mode work properly, but on all previous keystrokes it just highlights the next row in the list.
How can I enable the user to edit the data in the data grid view once the rows have been added ?
Here are a list of tutorials on ways to accomplish this here:

I would start with these.
What is the best way of editing a entire row on datagrid. Datagrid is bind to sql table. I would like to edit the changes and commit the changed field.
If possible a simple and easy solution for this problem would be gr8 if anyone could suggest me.
Thanks in advance
I quit using DataGrid for editing. I use the ListView then provide then provide a GridView as the ListView.View. Inside the GridView you can create GridViewColumns with CellTemplates. The last column of each GridView row is a button to delete that row. Instead of supporting a browse and edit mode, I just support an edit mode. The application moves more fluidly and I don't have any of the headaches that comes along with working with the DataGrid.
I have one GridView and one "Add" Button. If I click the "Add" button, one new row will be added to the GridView at the sametime I want to show "Update and Cancel" buttons in CommandField Column.
When I click the Update Button after the Insertion of the New Row, I want to Show the Delete Button in the Command Field Column.
Once again When I click the Delete Button, the Corresponding row will have to be deleted.
So far I have done all the four things(update, cancel, edit and delete) at the same. But now I dont want Edit.
The problem is when I include "ShowDeleteButton = True" in the command field, the "update and cancel" buttons are not displaying when I click the "Add" button.
The "update cancel" buttons are displaying only when I include "ShowEditButton = true". But I dont want to Edit the Column. Any one please help me.
Here I want only to do Update, Cancel and Delete. How to do? I dont want coding, I have written all the coding parts in Gridview_Rowupdating and RowDeleting Event.
Here is my GridView's Command Field Column.
