Inplace Edit in GridView

In this article I am presenting a different way to look at EditItemTemplate, using which user navigation for editing is reduced and . it looks very different (see screeen shots) then regular implementation of GridView.

Edit GridView Individual Cells in ASP.NET

The ASP.NET GridView allows for a row of data to be edited by setting the EditIndex property of the GridView, placing the entire row in edit mode.

You may not want the entire row in edit mode if you are using DropDownList controls for several columns in the EditItemTemplate. If each DropDownList has many options then loading them all at once may result in a sluggish page. Also, if your data structure is more like a 2 dimensional array rather than a set of rows, you may want to edit each cell individually.

Here I will demonstrate how to achieve this and also how to deal with event validation without disabling it.

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

How to let user edit selected gridview columns, not entire row



I've got a gridview I would like to let the user edit a couple of columns.  Seems like everything I'm coming across so far makes the entire row editable.  

Hopefully the solution isn't too complicated.  Can someone point me in the right direction?


Detecting Edit or Insert Page


I am coding a .cs file that handles the metadata for a particular table. I am putting a custom validation that allows me to update or insert only if the PubMedID is not already in the database. This would be easy except that the PMID should also be allowed to be null as some of the references in the database were not from PubMed. So i perform a query on the database to see if there is already an identical PMID in the database. This works great when using Insert. However, when using Edit, it does not. The PMID is already in the database because the one currently being edited has the same PMID!!! So I know exactly how to change my query etc. However, I do not know how to tell from inside this Edit/Insert agnostic page, which one it is being called from. Thanks for your help!

BuildingTable: (BuildingID, BuildingName)

AssetTable: (BuildingID,..,....,....)


ItemTemplate: Using a LINQ query I join the two table and displays in a label control a string which includes BuildingID and BuildingName (5 North Building)

jquery datepicker not popping up in Gridview Edit Template textbox


I have a gridview that I can't for the life of me get the datepicker calender to pop up for.  I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview.  I didn't expect any issues however can't seem to find anything to work.  I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail.  I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.  Please help!

Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)

Masked Edit Extender overwrites instead of inserts


 I have a masked edit C99999 as a mask and allow a "C" or "D" as the beginning character.

This C or D is added to an existing number when that application is Denied or Canceled.

The trouble is the masked edit is in overwrite mode and destroys the original app#.


Can I make it INSERT or do I need to do an append of the original number to the new

prefix in the update code?


I hope this isn't another RTFM question... <BLUSH>

Windows 7, IIS 7.5 and VS2010: can't edit global.asax


Hey and thanks!


As the subject line notes the software in use, anyone have an idea why I can't edit global.asax in VS2010 (being ran with the 'run as administrator' advanced property check box checked)?  The file properties in explorer show local machine admins have full control (I am in that category) and also that IIS has windows auth enabled for the default web site.  What is this other level of security on here that I'm missing?  I can edit web.config, vb files and general aspx files with no problem--just the global.asax file causing a headache...





How to use a drop down list to edit in the standard Edit.aspx with DD?


Hey All,

I'm brand new to Dynamic Data and to ASP.NET.  I've been able to fumble around and get the calendar extender up and running and a few other customization options implemented, but I can't seem to get this drop down list to work - even after reading tons of online info.  The good news is that my web page/application is VERY simple, so hopefully you guys can help me out.  I'm working in VB btw.

I have a list of road projects submitted to me by local governments.  One of the fields is SponsoringAgency, which has a limited number of possible entries (the names of member governments).  Thus, when they submit a new project, or edit an existing one, I want to limit the input into the field "SponsoringAgency." I'm trying to use a dropdownlist because I'm familiar with it from Access, but it may not be the best approach.  Imagine you just setup a brand new, standard DD website, how would you get this to work?

Methods tried and failed (probably because I don't understand them fully):

UIHint - The closest I can get with this is an error saying that since SponsoringAgency isn't a Foreign Key, I'm out of luck.

Creating a SponsoringAgency Table - In my data layer, I created a second table with a list of government names.  I then tried se
