I got a gridview to display the data from the database properly but when I go edit. it give me an error. I searched and change ConflictDetection=CompareAllValues to OverwriteChanges
The error goes away. However the database is still doesn't update. Does anyone had to tweak the gridview function to make it works. Maybe I did something wrong.
I try and update my table with the following
[Code]....
I dont get an error or anything, nothing happens, and the date remains the same.
Can't tell what is wrong here . It worked fine and I didn't did anything special in code-behind
I don't see any error just the same data in gridview

After the SubmitChanges call, the Text field in data2 wasn't changed. According to the NerdDinner sample, I supposedly can just write to my data object and then call SubmitChanges.
my table i have a column named [Name] nvarchar(255)[Name] can be a string witch can have some diacritics like "Ăă, Ââ, Îî, Țț, Șș"If i am using this, it returns for word "Antichități" the string "Antichitați"
[Code]....
But if i am trying to replace "ț" with "t", it doesn't work
[Code]....
The result is still "Antichități"How can i resolve this issue?
I've never used the RetrieveData() function and I don't know much about it.Having failed to work it out myself could someone show me some examples of how I call this method?Here's what I know about it:
1.It hadles the work of contacting the database and creating the DataSet.2. You must import System.Data, System.Data.SqlClient and System.Web.Configuration namespaces in teh web page.3. It can be called in any event handler in the web page code.I've tried typing this method in my page_Load() but I get the squiggly red underline which indicates that it doesn't recognise this method.
I have records with and without a email entered in the field called 'email'.
This one works:
Return From p In db.myTable _
Where p.Email.Length > 0 _
Select New With {.p.Name, p.Email}
but this doesn't
Return From p In db.myTable _
Where p.Email.Length = 0 _ ( nor does Where NOT p.Email.Length > 0 )
Select New With {.p.Name, p.Email}
Am I missing something?

sql update command. I have created two forms for update,
1. In first one I retrieve details in text boxes vai id entered by user.
2. In second one I display a grid and on the EDIT hyperlink I pass on the value of the primary key to another update page with same syntax as first one. When I click on update button on this next page, I get a successful update message but the data in the
database is not updated. Also I don't get any kind of error.
What is going wrong with the code?
Here is the code for the update page in second situation.. BTW I am displaying the details in a datagrid.
[Code]....
as seen from the title my sql doesnt update the data that has been inserted by my function. But in my function it works perfectly as it returns '1' when i executenonquery. however it only works when i insert a record which has a date later than today's date. which is weird as there is no validation in that page and if there were to have a validation, it would not run the function.
View 10 RepliesIs it possible to perform an update command which performs addition using a value from a textbox? For example: User inputs a number into TextBox1 (I use regular expression validation to ensure this is an integer).

Basically if the user inputs 5 into TextBox1, I want the update command to subtract 5 from that user's ballance.

View 9 RepliesI use ADO.net Entity Data model for work with database.
In my program, I want to update a record of user table, so I use the code below to do this.
In this function I send changed user info and then overwrite the information with the current user information.
After I run objUser = _user; and then call objContext.SaveChanges(); to save the changes.
But when I do this, the changes are not persisted to the database. I use this code for another programs but in this case the code does not work!
public void Update(tbLiUser _user)
{
LinkContext objContext = this.Context;
tbLiUser objUser = objContext.tbLiUsers.First(u => u.tluId == _user.tluId);
objContext.Attach(objUser);
objUser = _user;
objContext.SaveChanges();
}

This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?
