MVC :: Deleting Record
Mar 24, 2010
I've followed a blog here on removing a record. this is what I have. everything works except the page doesn't refresh after delete has been called as if it's doing it in AJAX. I only see the change when i do a manual page refresh. [URL]
Master Page Head section
<head runat="server">
<title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title>
<link href="../../Content/Site.css" rel="stylesheet" type="text/css" />
<script src="../../Scripts/jquery-1.3.2.js" type="text/javascript"></script>
</head>
Index View:
<% foreach (var item in Model) { %>
<tr>
<d>
<%= Html.ActionLink("Edit", "Edit", new { id = item.LogId })%> |
<%= Html.ActionLink("Details", "Details", new { id=item.LogId })%> |
<a href="/Log/Delete/<%= item.LogId %>" onclick="$.post(this.href); return false;">Delete</a>
</td>
<td>
<%= Html.Encode(item.CampaignId) %>
</td>
Controller:
//DELETE
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Delete(int id)
{
try
{
_repository.Remove(id);
return RedirectToAction("Index");
}
catch
{
return View();
}
}

I am trying to delete a record being displayed in a table on my ManageUser view using a sub-form, thus
<table cellpadding="2" cellspacing="0" border="1" summary="User Grid" style="text-align: left">
<tr style="background-color: #ABC3CB;">
<th align="center">User Name</th>
<th align="center">Approved</th>.....
but instead, it is returning directly to the Admin/ManagerUser view, thus displaying my original set of records again.

I have a form that when I click the delete button I want it to refresh the grid with that record removed from the grid. Does anyone know how to do this. Is this something handled in the code behind? Here is my code for the delete button on the design page:

I have a dropdown list, and can select names to delete from db table user.
Just want to add a confirmation dialogue window before deleting the record.
I am using a simple function at js to confirm. Isn't that enough to go to btnDelete_click() if true? I am using LINQ to SQL.
I tried:
(code behind)
protected void Page_Load (object
sender, EventArgs e)
{
if(!IsPostBack)
btnDelete.Attributes.Add("onclick","return check();");
}......

I have a gridview and a SQLDataSource control. In my gridview I have 2 commandfields "Edit" and "Delete"
The "Edit" command field works as expected. Using the "Delete" command field I get the error below.
Server Error in '/DataControls' Application.
The DELETE statement conflicted with the REFERENCE constraint "FK__titleauth__au_id__0CBAE877". The conflict occurred in database "pubs", table "dbo.titleauthor", column 'au_id'. The statement has been terminated.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I am using a Gridview inside an UpdatePanel. I am using the RowCommand method to call my code to delete the record. The gridview is bound to a <list> collection. I am unable to get the Gridview to postback / refresh after the users deletes a record; however, if I refresh the page in the browser and the page loads, it obviously is gone. I have searched quite a bit on this where others are having problems but nothing they did work for me, so I was hoping someone could review my code and let me know what I am doing wrong.
Here is my ASPX:
[Code]....
Here is my C#
[Code]....
When I step through the code, the postback happens and then my delete code is called, so once the delete code happens, the page is already finished loading, which seems to be my problem.

I have two tables with one common field. The field is the primary key in one table, and just a plain field in another. When I delete a record in the table where the common field is the primary key, I want to automaticaly delete a record in the other table that has the same data in the common field.
What is the most effecient method of doign this..triggers?

I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.

how can i retrieve the all foreign keys against a single primary key. i mean to say that if a table contain a primary key then it becomes as foreign keys in which tables.
i want to take that nam of that tables and on the base of that tables then i am to delete from all the entries. e.g: if a primary key's column entry deleted then all foreing key entries should also be deleted.
there are 988 tables in a single database. it can't be possible to go for each table to setup foreign key to ON DELETE CASCADE.
.can it have any way to delete against foreign key priority wise? mean to say that parent table contain primary key, child table contain foreign key , now there is another child table which dependent previous child table. then how can i delete all record against it?
i want to do it from programatically. i am using sql server 2005
i have completed this till to that , it retrieves all foreign keys but how to delete now on the base of priority.

I am having trouble changing page numbers on my gridview after deleting a record if the deletion of the record causes there to be no more records on that page. Currently I have a form below the gridview that adds a record to the datasource of the gridview.
[Code]....
Code behind stuff:
[Code]....
Now with this code above, if I insert a new record using the form below the gridview, it will reload and go to the new page if the insertion causes the record to appear on a new page, however when I delete that record, thus causing nothing to be on that page, the gridview visually just dissappears. I've got the gridview bound by a linqdatasource control, and on the page_load function I only databind if the page is not a postback.

Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...

I have a DataGrid that I need to be able to use to delete records form a file
[Code]....
[Code]....
I use
((TextBox)GridMenuOptions.Rows[e.RowIndex].Cells[1].Controls[0]).Text;
To access the data in the Grid for updating, but it doesn't work for deleting
I can use
string id = GridMenuOptions.DataKeys[e.RowIndex].Value.ToString();
but that only returns the first key.
How do I access the rest of the keys?

I have a bound data field, a detailsview, one of the records I have formatted to currency in the item template. Yet when I go to delete a record, I get a error message "Input string was not in correct format". Take away the formatting and the page runs fine. I tried changing the datatype from int to money, it makes no difference.

I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1
2 Record2
3 Record3
4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1
3 Record3
4 Record4
...if I then hit refresh...
1 Record1
4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server">
<asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" />
</asp:LinkButton>
protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) {
if (e.CommandName == "Delete") {
int ID = e.CommandArgument.ToString().Numeric();
db.SPs.SpDeleteAccount(ID).Execute();
UI.Confirm(uiBroadcast, "Account has been deleted", "300px");
BindAccounts();
}
}

I'm very new on VWD, but I got the hang of it for the past 2 weeks(thank you for all the videos posted here in ASP.NET),but I'm really weak on the coding part(vb & c#),except for all the sample shown on the tutorials. Anyways, I have a simple project that
does insert, update & delete to SQL express using the details view. But to complete my project, I need to add a button that will create an event to restore the very last record inserted in SQL and display it back into the details view for minor modification
and nserted again as the newest record with the mod. I'm doing this so user, doesn't need to re-key-in redundant information, like names, original date & time etc, and just make modification on the description of the last record.....

I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
