Does anyone know how to program a Confirmation box to pop up when deleting a row in a ListView Control in ASP 3.5 in VB? I have the delete buttons in both the ItemTemplate and AlternatingItemTemplate.

I am abble to wrangle the code to work with a generic message but without understanding this piece I am unable to figure out how refrence my own data.
I have created a ListView with a SQL DataSource. It has Item Template, Alternate Item Template, Insert Item Template, Layout Template, Edit Item Template & Select Item Template. There are delete buttons in the Item Template, Alternate Item Template and Select Item Template. The Delete command is
DeleteCommand="DELETE FROM [ClientNoteType_Lookup] WHERE [ClientNoteTypeCode] = @ClientNoteTypeCode"
which seems correct. I have not selected Use Optimistic Consurrency when I configured the data source. When I click on the Delete button, it deletes the selected record and the record after. THe ClienNoteTypeCode is a varchar(4) field and all codes are unique. It deletes both records in SQL Server when the button is clicked, but one one is deleted on the web page until I refresh the page and then both are deleted.
I want to confirm from the user before deleting a record. I want to show a message box to confirm operation... How I do that.. I used query to delete a record on button's click event..
View 1 RepliesHow Can I appear Confirmation Message Before Deleting in ASP .NET MVC Page
View 3 RepliesI 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'm using this code;
Code:
Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
Dim l As LinkButton = DirectCast(e.Row.FindControl("LinkButton1"), LinkButton)
l.Attributes.Add("onclick", "javascript:return " & "confirm('Are you sure you want to delete this record " & DataBinder.Eval(e.Row.DataItem, "CategoryID") & "')")
End If
End Sub
but i still encounter these errors:

I have a ListView that displays comments for an article.Each comments has a button that, when clicked, deletes that comment provided that the logged person is the comment's owner or an administrator.
I need a way of storing comment's ID in the ListView somehow and then I need to check if the ID of the comment's author is the same as the ID of the logged user (which is stored in the Session) and then, if they match, display the button that deletes the comment when clicked.
i need to get data-bound items from outer listview to display in inner Listview, in this scenario:

View 6 RepliesI have a ListView, I've setup to use an ObjectDataSource, I've created my Layout and Item templates, and I'm able pull and view a list of my data no problem. However I want to add delete capabilities to my
ListView and my reference material tells me to go into the "Configure ListView..." option under the ListView's smart tag, the only problem is I don't have that option, the only three options in my smart tag are "Choose DataSource", "Configure DataSource..." and "Refresh Schema", what am I doing wrong?
I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
View 8 RepliesDoes anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.

I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.

If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.
Ok, background first:
The form allows a user to create and edit one estimate.
Each estimate can contain multiple Jobs, which are represented in a ListView.
Each Job can contain multiple Parts, which are contained in a ListView that sits in each item of the Jobs ListView.
A user can add and remove as many Jobs as they want.
A user can add and remove as many Parts to/from each Job as they want.
I have no issues adding to each of these, but I do have a problem removing a single part from a single job.
For a reference, here is one Job in the Jobs ListView on the form:
I want to make sure that no matter what a user does, the part of the form they are working on saves what they have. Removing a row from that Parts ListView is no exception. What I want it to do is save the values in each of those textboxes and then delete the necessary row.
Here's what I have in the codebehind:
[Code]....
The EstimateRow variable I create does not get a value from theListView)HFERID.Parent.FindControl("LVEstimateRow") bit of code. There must be another level of nesting that I'm not accessing correctly, because it can't seem to find that nested ListView.
I have a datakey defined on my outermost ListView. When I click on a linkbutton in a row in this listview, the second listview is displayed. This inner listview has several controls and also a linkbutton. When I click this linkbutton, it gets handled by its own event; linkbutton_click. In this event all the data is collected from the innermost listviews' controls, and sends it to the database. The only thing I need within this event is the datakey from the outermost listview.
