DataSource Controls :: GridView Update Function Doesn't Work.
Jan 27, 2010
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.
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 a simple query on a table to calculate the sum of a field (This field is a calculated field from within SQL 2005)SELECT SUM(RunTime) AS TotaL FROM TimeSheets.It errors out with: Error Message: Operand data char type char is invalid for sum operator.If I use the MAX or MIN function, no isssues. The data in this field is numeric.
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.
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.
Is 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).
[Code]....
Basically if the user inputs 5 into TextBox1, I want the update command to subtract 5 from that user's ballance.
I have a gridview connected to my objectdatasource, i wrote a class for the database queries.Now when i do an update of record i get the id form the grid, when i click on delete i don't get the id, its 0.Is there an option to set the id? i can't find it in the gridview.
Im using File Upload Control in every row of a GridView.... Like tis
Name UploadFile textBox FileUpload TextBox FileUpload . . Submit
On Submit im first uploading all files present in the grid and then saving other values in database....No Problem when uploading Small Set of filesIf i browse more than 10(approx) files(i.e 10 files in 10 rows) and Submit... Internet Explorer-Page Cannot Be displayed Error occurs but no problem when uploading < 10(approx) files....
the datatype in my database is Varchar, so that my gridview Sorting Function doesn't sort correct in sequence 1,2 3, 3 but 1,10,100, how can I sort in sequence 1,2,3,4 but no changing the datatype in database?
I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why???
This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.)
I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:
[Code]....
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?
