Forms Data Controls :: Gridview Delete One Row Only?

Mar 28, 2011

I have a gridview control on my page that lists records and sorts them according to the most recent to the oldest record. The most recent record is first record at index 0, and I want the users to be able to only delete the first record in Gridview. Is this at all possible? I'd like there to be the word 'Delete' next to the first record only.

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?

Nov 18, 2010

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";

But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.

Specified argument was out of the range of valid values. Parameter name: index

How do I reference the delete button so the edit button is not affected in this case?

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically).

Here is my source code.

and I added this as a Gridview column:


and this is the error I get:

Forms Data Controls :: How To Delete A Row From A Gridview

Oct 7, 2010

A very simple question.

I am trying to delete a row from a Gridview but getting error in my Gridview1_Rowdeleting method on the line Gridview1.DataKeys(e.RowIndex).Value;

Error: Method, delegate or event is expected. Here is my Gridview

<asp:GridView ID="GridView1" runat="server" OnRowDeleting="Gridview1_Rowdeleting" DataKeyNames="RecAdvId">
<asp:buttonfield headertext="Delete" commandname="delete" datatextfield="MessageId" />
<asp:BoundField DataField="RecAdvId" HeaderText="RecAdvId" Visible="false" SortExpression="PanelId"
<asp:BoundField DataField="Advert" HeaderText="Advert" HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />

Here is my code behind method which gives error:

protected void Gridview1_Rowdeleting(object sender, GridViewDeleteEventArgs e)
int x = _Gridview1.DataKeys(e.RowIndex).Value; //Error: Method, delegate or event is expected.

Forms Data Controls :: When Gridview DELETE Bombs?

Dec 7, 2010

I have several "standard" GridViews in the "admin" side of a web site I am developing. In the past, none of these have ever shown any problems with a standard Delete.

To review: Each of the subject tables has a "RowID" field specified as Identity and as the Primary Key.The BoundField for the Rowid is set to ReadOnly. There is "Edit, Delete, Select" specified for the CommondField. Edit and Select operate as they should.

HOWEVER, Delete results in a "Must declare the scalar variable "@RowID" (with the associated "unhandled exception" verbiage).

The DeleteCommand text in the SqlDataSource for the GridView reads

Forms Data Controls :: Gridview Clearing Out After Delete?

Mar 4, 2010

I have a gridview which at run-time contains X number of records. Upon clicking a DELETE linkbutton on a particular row the gridview completely disappears from the page, when it should reflect simply the loss of that one record. Everything is okay on the database end, the record is deleted, so I know that part is working. I run a query and rebind the gridview within the Rowdeleted event. I even try hardcoded a value in the query which I know exists in the database and it still doesn't refresh with this record showing. Whatever code I need to post, let me know.
