Add a button to update in 1 click to a gridview control


Hi all, I know that from the title probably everyone is going to think, "why add an update if is already there!"  the reason is because I want to update/delete/add with one click, instead of click the edit button, modify the data and then click the update button.

This is my scenario, I have a gridview with information of tools(screw driver, hammer, etc) one of the columns is the status, so what I want is to add a button that the user can click and chance the status from "Assigned" to "Active" this is what I have so far:

<asp:GridView ID="GV1" runat="server" AutoGenerateColumns="False" CellPadding="4"
                        DataKeyNames="IdTool" DataSourceID="Tool" ForeColor="#333333" SelectedRowStyle-BackColor="AliceBlue"
                        SelectedRowStyle-Font-Bold="true" Width="605px">
                        <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
                            <asp:TemplateField ShowHeader="False">

In-Depth look at the GridView Control

In the last article we looked at few of the new controls available in Asp.net 2.0. We also talked about Grid View Control which has replaced the Asp.net 1.1 DataGrid control for good. In this article we will examine more features of the Grid View control. In this article we will see some of the common operations that can be performed using the GridView control. Apart from these operations there are many more functions that can be performed on the control and which we will see in the later articles

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 format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Using TemplateFields in the GridView Control

The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.
