C# - How To Program Edit Button For Gridview Through Codebehind
Mar 4, 2010
I am trying to generate a gridview dynamically through codebehind. So I am making all the columns through code using BoundField and other controls.Now I am trying to to put a edit button in the gridview sand program that(I made a RowEditing handler). Right now all my code is in the page_load but when I hit the edit button in the gridview I get 2 gridviews back on post back.So I tried to put a isPostback if statement to stop this but then I just get a error back saying it can't find the handler.

In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
I used below code for above:
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"

is it possible to have a button that points to a method you have defined in codebehind, that passes in a record from the row as a parameter? for example, id.something like:
<asp:CommandField ButtonType="Image" EditImageUrl="/editbutton.jpg" ShowEditButton="True" OnClick="editRow(int id)"/>
it wouldnt necessarily 'edit' this row. i'd like it to instead load an editable grid corresponding to the id passed.

I have a Grid View. I added AutoGenerateEditButton=True.
I want to display that button to users that belong to a certain role. If not the button is not rendered.
What do you recommend? Which event do I have to handle to accomplish that purpose?
Do I have to work with template-driven control such as ListView?
Solution:

<cc1:ModalPopupExtender runat="server" CancelControlID="btnCancelEdit" OkControlID="btnOkEdit" BackgroundCssClass="ModalPopupBG" TargetControlID="PanelCountry" PopupControlID="PanelUpdateCountry" BehaviorID="Edit_Country">
</cc1:ModalPopupExtender>
[Code]....
It is working for me but the major problem is that in modelpopup extender in which i have given targetcontrolid of PanelCountry so when i click on next page of Gridview in it opens a PopUp,while i want to open popup when Edit button of Gridview is clicked not for next page of Gridview.
I mean how i will set the TargetcontrolId of Edit button of Gridview in PanelCountry for modelpopup.

In my gridview, when in non-edit mode, my edit (pencil) and delete (X) buttons show up side-by-side as expected:
Attachment 130089
However, when I click the edit button (pencil) to go into edit mode, the update (diskette) and cancel (undo arrow) appear as shown below, and the edit and delete buttons of the other rows appear the same "wrong" way as well.
Attachment 130091
Here is the code for the grid:
Code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" GridLines="None">
<AlternatingRowStyle BackColor="#F7F4ED" />
<Columns>
<asp:BoundField DataField="Fname" HeaderText="First Name" />
<asp:BoundField DataField="Lname" HeaderText="Last Name" />
[Code] .....

I have a simple GridView with AutoGenerateColumns,Edit and DeleteButton = true
It's data source is a DataTable dynamically generated.
Since i don't want to use object data source, i just catched Delete event and deleted rows from datatable and made a new databind. It works.
I tried to use also AutoGenerateEdit button, but when i click on Edit command field, nothing happes. So i decided to handle by myself edit events, and changed datagrid in this way:
<asp:GridView runat="server" ID="dettaglioprodotti" BackColor="White" BorderColor="#DEDFDE"
