Why would you want to view the design ? I mean, the designer is really not a great tool, it's far better to write your own script and run the page to view it.
But yes, you can turn off the HTML validation, but you'd do better to fix your HTML.

Besides memory consumption, are there any issues I should be aware of when keeping DataTables in a session object?
Here's my situation:
When a user adds a new entry into the database, there are of course a pile of related child tables that have to be filled in as well. When working with a new record, there won't be an valid ID for the parent record so I'm doing everything in memory until the user hits 'save'. I've already got a couple of my GridViews working fine but I was wondering if there where any gotcha's.
Thanks!

My 1 cent to this
1) May be you can try using a staging table in db to store this temporay values and when the user hits save; copy from staging to the main table.
2) Or Create a view state object and add the data table to it.
Thanks

1) So have a set of duplicate temp tables in the database? Maybe use the user's id as the record IDs.
2) Question, why would you use view state over session objects? I guess the view state would save memory on the server but it wouldn't the increased page size slow down the user's browser? I guess using AJAX update panels would help with that.
Thanks for your response!

1) Ya, UserID,Session ID cound serve as he primary key and when the user clicks save copy and insert to the main table and delete the same from temp table.
2)
a) The good thing of View sate over the session variables is that you can dispose then once done with it.
b) Update panel does nothing more than hiding the user from seeing a full page refresh by interepting post back.Behind the Scenes it does everything that needs to be done with out its presence.

Hi, what I do in those cases, is set the related column in the child table as not required(allow nulls), then I save the parent data and I get the new ID, with that new ID I will fill all the child tables and then I save them.
Geek to the bone.

Create a custom class that's stored in Session with it's own Save() method that will write to the DB. The DataTable probably has more information than you need and will waste more memory by storing it in Session. You can bind all your GridViews to the class just as easy.

That seems like the best solution. Use an array to hold the data and built an interface around it.
Thanks!

ASP.NET is a method for outputting HTML to a user's browser. No part of this ability allows you to interact directly with a user's computer.
Seriously, how do so many people who decide to write ASP applications misunderstand ASP?

Given that the task is impossible, 'as early as possible' means never. As someone else said, why do so many people who post here have no idea what ASP.NET is, and how it works ? I recommend you buy a book on ASP.NET and read it.

You can put img tags in side your table row, and I assume these will appear over the background image. Are you trying to put rounded corners on a table ? You can do this with CSS instead, if the background is solid, but if it's solid, you shouldn't use a background image at all, just set a background color.

Hi
I am using an ajax update panel and within it there is a gridview control with item templates that have a fileupload control and a button that uploads the file chose.
I know that AJAX has problems with regard to using fileupload's and this is the solution: http://www.codeproject.com/KB/ajax/simpleajaxupload.aspx[^]
This (trigger) does not work as my button is within the gridview's template columns and I get a runtime error saying that cdmUpload can't be found.
Is there any other way that I can reference the control so it can be found?
Or any other method where I can use the fileupload control within the updatepanel so it actually works?
Any help would be great.
Thanks
M

Ya you can do this.
1) Add a buton Say btnUpload Inside the update panel
2) In the button click event right the code to save the uploaded file in the server.
3) In the Updae panel trigger collection add a postback trigger for the btnUpload Conrol.
Thanks

Thanks for your help, but i tried this, and the button control cannot be found as it is within the gridview's item template.
Is there no way to find the button other than:
<Triggers><br />
<asp:PostBackTrigger ControlID="TabContainer1" /><br />
</Triggers>

Hi to everyone!
I have one problem, when I want to make an update to some record in the table, I am entering the data for it, and instead just for one field, the UPdateCommand is putting the same data in all the fields. Example:
I have two fields: ID and Name. And I am making an update of the name, and it's changed all the data for all the fields under Name. I think that I should use some WHERE statement, but I am beginner in SQL and every help will be appreciated. Thx
Example, before update, I had:
ID:1
Name:a
------------
ID:2
Name:b
-----------After update-------------
Update name: "c"
ID:1
Name:c
------
ID:2
Name:c
-------
|
|
|
|
|
use where id = 'whatever one you want to update'
|
|
|
|
|
well, when I am putting WHERE [id]=@name I get this error:
Conversion failed when converting the nvarchar value 'edenss' to data type int.
and when I am putting WHERE [id]=@id I get update of all the fields where the ID is existing.
|
|
|
|
|
where id = @id should work
you need to make sure it is jus selecting the one id
can you post your whole code
|
|
|
|
|
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="">]]>"
SelectCommand="SELECT * FROM [tblname]" InsertCommand="INSERT INTO tblname(name) VALUES (@name)"
UpdateCommand="UPDATE [tblname] SET name=@name WHERE id = @id">
<insertparameters>
<asp:parameter name="name">
<asp:parameter name="name">
|
|
|
|
|
where is @id declared, what is it? textbox value, hardcoded value?
