How do I control using ListView when to show the Update/Delete/Insert buttons and when not?

Posted By:      Posted Date: October 03, 2010    Points: 0   Category :ASP.Net

It should be simple, but I didn't found yet how to do it.

There is only one user (Admin with user name and passowrd, he has a cookie so I know when he is watching the page) I would like to show him the Update/Delete/Insert button options in my ListView, but to the other users I don't want them to be able doing this kind of things, So it should be hidden from them.

How I am doing it in C# code?

Showing/Hiding these buttons?

How to perform insert, update, delete and select rows in ASP.NET gridview control using stored proce

In this article, we will explore how to add, update, delete and select a record from sql server database using gridview control in a simple way. I'm using visual studio 2010 and sql server 2008 for this sample.

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

How to Delete from a SortedList using Listview Control

I'm new to Asp.net, and I looked at an example of using a listbox's selected index to delete from a sortedlist. I'd like to write something that would get the selected index from a different control, like a listview, and then delete from the sortedlist. I've read up on a few examples on how to bind data from a sortedlist to a listview, but I've not seen an example of how to get the index once the data is displayed! Can this be done? Thanks for any response!

Allow or deny roles to update, insert and delete records.

Hello, I have two roles "Admin" and "Basic". I also have a listview on the web page. My goal is that to make "Admin" role has the highest privilege to deal with records such as "insert", "update" and "delete". For the role "Basic", it only can update the records. Is there any sample code for that? Thanks.

Hi, I'm stumbling along trying my hand at Linq to SQL and have come across this code below that was provided by MS.http://msdn.microsoft.com/en-us/vbasic/bb737928.aspxThe problem is there is no ".add" method for Categories to chose in the statement db2.Categories.add(newCategory)I've seen similar videos here on ASP .NET that uses code very much like the example below, but I am unable to run this example connected to a Northwind SQL database using Web Developer 2010 Express.

Update, delete, insert

I have two databases.  When I am using MS Visual Web Developer, I can drag the table onto the webpage and it gives me check boxes to Insert, Update, Delete,... When I do the exact thing using the other database, it only has check boxes forpaging, sorting and selection.  What is the difference?  I seem to have all teh same permissions in both databases. How can I make the second database update, delete and insert?

Can I use a DetailsView control to insert and update with RIA services?



I'm struggling with trying to use RIA services from an ASP.NET web site.

I created a new web site, added an entity framework model, then added a RIA service that uses that model. I used the DomainDataSource control to bind the ASP.NET controls to the RIA service.

I have a GridView that shows items from the database (via RIA and the entity framework model underneath it), and can see the items fine. I added a DetailsView as a pop-up, as shown in http://mattberseth.com/blog/2007/07/modalpopupextender_example_for.html and http://mattberseth.com/blog/2008/04/masterdetail_with_the_gridview.html. When I click the "edit" link in a row in the GridView, the DetailsView shows with the right data, but clicking the "save" link doesn't actually update the database.

Furthermore, I can't work out how to add new items this way, as when I try and use the DetailsView to add a new item, nothing is sent to the database.

Anyone any ideas how this can be done?


SSIS : Insert, Update, Delete records from destination table by comparing records in source table.


Requirement: Inse

rt, Update, Delete records from destination table by comparing records in source table.

Update: if records exist in both the table compare them, and update value in destination table if value is different.

Insert: if record doesn't exist in destination table, add new record in destination table.

Delete: if record exist in destination table but not in source table, delete record from destination table.

----> I have created an SSIS package that does all this task but in order to perform delete operation, I have to store all records of destination table into a temporary table.
And since it's not the most efficient way, I have created another SSIS package by using Lookup & conditional Splits
method, now it works fine with inserting and updating information but I am not sure on how to handle removing record operation!

I would really appreciate if you could help me with this.

(In order to archive inserting and deleting records, I have referred following thread!

linqDataSource control - auto update/delete feature - when there is a join?



I've used the linqDatasource control (combined with listView) with it's features supporting automatic insert/update/delete for tasks who's data resides only in one table.... Now I have a scenario where I need to include a join in the linq query that will return the data for the linqDatasource control... will I still be able to use the linqDatasource control's automatic update/delete feature? I'll be using the linqDatasource contro's 'selecting' event to craft the query to return the data that will be bound to a listView control. All the fields of the table that I need the updates/deletes on will be included, but I need to pull in one field from another table for viewing purposes only, don't need to update/delete it.
