Editing the Data in a GridView

In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.

How Do I Enable Inline GridView Editing?

Now that you have created a site with Edit and Details views, how do you enable inline editing in a GridView control? This video shows you how, and also touches on routing.

Gridview with a dropdown list for editing


Hello. I am working through Scott Mitchell's ASP.Net in 24 hours book. I am finishing the photo album project.

I have a GridView that retrieves a list of uploaded photo rows for the logged-in user.
The GridView is for editing and deleting rows.

The photo Category field in the Gridview is a dropdown list. The text entry field was deleted after converting this field to a Template.

Like the uploaded photos, these Categories are user-specific. They are created in another web page.

Users also have the option to select "none" for the category when they upload an image.

For the GridView:  The Category ID field's ItemTemplate and EditItemTemplate both have a " - None - " choice added to them.

I am getting this error:

'pictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value


Note: The ID for the ItemTemplate for that dropdown list is the ID listed above in the error: "pictureReadOnlyCategories".


Am I missing some step in this process of changing a GridViews text field to a dropdown that can be used for editing? I went through the book's instructions three times.

Here is my code for the dropdown list and a screenshot of the Design

Gridview extends past edge of div and page when editing users


I have a gridview pulling all data from one user. This gridview has an edit button and when that is clicked the gridview becomes too wide for the div/screen and I get a scroll bar. Since this gridview can only have one user in it anyway is it possible to display each field on seperate lines instead?

gridview tablecell text emptystring in RowDataBound event when editing


HI and thanks in advance.  asp.net using vb, using a codebehind page.

I have a relatively simple gridview bound to an product table that displays great.  The problem comes when I choose to edit a row.  When I do so, the gridviews' RowDataBound event fires and the values of the text properties of the tablecells in the row evaluate to "" emptystring. 

I do notice that if I break within the GridView1_RowDataBound event during a refresh of the page, the values are there.  But again, when I hit the "Edit" button in the first column (the CommandField column) .  Text properties of the cells resolve to ""

 Here is the code for the event, followed by the gridview in the form (inside an updatepanel)

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  ' not a header, footer row.. etc.
            Dim cellProductNumber As TableCell = e.Row.Cells(3) ' ProductNumber column

'>>>>> after clicking "update", even though a value displays in the gridview,
' the cellProductNumber.Te

Creating a gridview to allow editing of current users


I finally got membership and roles setup and seems to be working.

I have setup a page to allow the creation of a user and editing of roles for a user.

I would like to setup a page with a gridview that displays all users and what roles they are assigned. I remember running across someone else that was looking to do the same thing, but cant find it. Not sure if it was in this forum or online somewhere else.

But i found that i can use the  aspnet_Membership_GetAllUsers procedure in my db to get all the users, but how can i add the roles to each person and possibly setup the gridview so that each role they have, is displayed on their row in the gridview

So i would like to see something like this maybe more data displayed depending on the client request.

Username                 Email                 Last Login                          Roles

GridView editing without using data source controls?


I am binding my gridview without using a datasource control and instead doing it in the code behind. However, I would like to use the inline editing features of the gridview. Could someone please point me to an example that does gridview editing/updating 'manually' in the code behind?


Editing Image in Gridview VB.net

Hi, i'm back again and would like to seek help and advises from you experts on how to deal with problem. I have a table that accepts news data like title, content, link and a single image to be uploaded and attached to the database (not on file server). Now i want this Image Column (varbinary datatype) to be edited in case. When I tried puting an html fileupload in editing mode using gridview, I am getting error from the Image Column conversion like Image type cannot be converted into string. I know there is this scenario of reading and assigning data in my table, and then changing some codebehind and at the same time binding it into the gridview.This is my Image Handler:<%@ WebHandler Language="VB" %>Imports SystemImports System.WebImports System.ConfigurationImports System.Data.SqlClientPublic Class Handler : Implements IHttpHandler        Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest        Dim con As New SqlConnection()        con.ConnectionString = ConfigurationManager.ConnectionStrings("automotiveConnectionString").ConnectionString                ' Create SQL Command           &n

New paragraph when editing text in gridview

I have a gridview which I use to edit text fields. How is it possible to start a new paragraph when entering text? I'm hoping that this can be done without using markup, as the users are not neccessarily going to be particularly computer literate.

GridView Confirmation Box Using JQuery BlockUI in asp.net

JQuery is the most popular JavaScript library. One of the main reasons for its fame is the plugin architecture. Anyone can create a separate library that leverage the JQuery library. In this article we are going to look at the BlockUI library which is used to block the user screen while performing a task.

Textbox Editable GridView in ASP.NET

This article describes how I made a fully editable gridview in C# using ASP.NET 2. The idea is that the GridView looks and works like an Excel spreadsheet. You see all the cells in the table, and you can edit any of the cells you like, and they are automatically updated (i.e. saved to the database). This is very often how people expect data tables to work in web pages, and I've often seen people clicking in vain on un-editable gridview cells, somehow expecting to edit them, and not understanding that they need to click an Edit button at the end of the row.
