Unable to add update and delete functionality to any data control using MS Visual Web developer Express and SQL server 2008. The advanced options in the data connection wizard remain disabled. I can display data OK.
I am however able to connect to an Access 2007 DB through the same page and get this functionality to work.
I would like to implement code to delete the selected row in the gridivew using Radiobutton .

Is there some kind of simple database system that uses simple text or xml files for data storage? I just need some basic functionality like update,delete, insert, simple constraints and relations.For the project that I have now using SQL Server would be too heavyweight and I have never really liked it anyway.
View 6 RepliesEdit and Delete functionality works flawlessly in Gridview if all data is pulled ONLY FROM ONE TABLE. But pulling data from one table give you ID's instead of actual values that are stored in other tables.
After creating a usable Select statement that would pull all the correct values, my Edit and Delete functionality no longer work.
Here is code.

I'm struck at editing the row which is displayed after search operation being performed. I've a table that has User_ID, Name, Status. I would like to bind data and display in gridview. I've implemented a search box to search fr the name and edit the status of the person. But if I'm trying to implement edit option on the searched entry it is not working as how I needed .
<asp:Content ID="Content2" ContentPlaceHolderID="Dresses" Runat="Server">
<div>
<table>
<tr>
<td>
Search
</td>
<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

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"
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
I have a record in gridview contains string with special character like single quotes( ' ) etc..I've a edit button in gridview when i click on edit button of any record of Gridview then corresponding record shown to text box.
But on that time single quote looks like below ....
Before edit button click string in gridview cell, a testimonial or show consists of a person's written or spoken statement
After edit button click string in textbox, a testimonial or show consists of a person's written or spoken statement but when I click update button shows following error :
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$tb_comment="...f a person's written or sp...")"
What is the solution so that single quote shows as it original format as it looks in gridview cell when i click on edit button.
How can I show data of a table into a page by using Data controls and add insert, update, and delete buttons?

View 1 RepliesI have three tables:
Colour(Colour ID, Colour)
DogColours(ColourID, Dog ID)
Dog(Dog ID, Breed)
Colour ID and Dog are primary keys.
I have three web forms, one for each table. Dog colours consists of data that is already in the system from the other two tables. It basically joins a breed to a colour. My problem is this:
When i try delete a dog which is being used in dog colours the program crashes. How can i prevent this crash?
The second problem, the data source in the dog colours web form has the insert, update and delete tick boxes greyed out in the 'configure the select statement' so i am unable to delete a colour and dog joined together. how can i delete something in the dog colours?

Now I need to make all the data editable (add, update, delete). Why isn't the Gridview the same as DataGridView? With the DGV, the data showed EXACTLY as it did in the database and one could add a record, edit a record, or delete a record.
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.
View 2 RepliesI have a page that is using the value from a textbox on a previous page to populate a formview. When I generate the Insert, Update and Delete Statements in Web Developer the edit brings up a blank page and the insert and delete don't work. It works if I just create the formview on a page and hardcode the value in the select statement then the Edit/Delete and Insert works.
View 3 RepliesIm a newbie, hoping any experts can lend a hand. I have a gridview table connected to an SQL database. I have auto generated the update and delete methods to allow me to edit the gridview.
However, I would like the editable data in the gridview to be replaced by a selectable drop-down box. The drop down box is referencing an sql table for selection.
I want to Add, edit, delete and update the records using gridview with validations.
I am not using any default datasources like sqldatasource or accessdatasource.
Want to do it in code behind.
Validations should be used as if some one try to update the value as blank or do not enter characters/numbers like that.
I have a following generic list method that contains some data for a gridview. I need to supply edit and delete functionality for it.

View 2 RepliesI have 3 gridviews in one of my web page, each of which will display different data based on the typeid. I have simplified the system structure in the image below(further description will be stated below the image):
As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews.
During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.

However, the Update(command button) and Delete(template field) doesn't work,the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource.
I have a gridview that pulls data from two tables, CLIENT and PAYMENT. I want to add the edit, delete functions to the gridview for the payment portion of the table, that is to edit or delete the payments but not the client. I've manually enabled the edit, delete functions and input the queries. I've also deleted the textboxes from the templates which draw from the CLIENT table so they cannot be edited. Everything looks good on the surface until I actually go to edit or delete anything, and it has no effect.Here's the structure of the two tables:
CLIENT PAYMENT
ClientID Pk PaymentNumber Pk
FName CLIENT$ClientID Fk
LName PaymentDate
ContactNo NULL PaymentAmount
ArrivalDate PaymentDetails NULL
DepartureDate NULL
CurrentResident
Here's the update query:
UPDATE [PAYMENT] SET [PaymentDate] = @PaymentDate, [PaymentAmount] = @PaymentAmount, [PaymentDetails] = @PaymentDetails WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate
AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails) OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))
Finally, here's the delete query:
DELETE FROM [PAYMENT] WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails)
OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))
I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List?
Which one is better, I mean ObjectDataSource or SQLDataSource or my XML method?

all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.
