i have the following url on pageload when i clicked on an image in a datalist: "http://localhost/MetSysClient/Pages/pgEDetImg.aspx?sImageName=Sunset"
how can i extract the value of sImageName which is Sunset and place it in a string variable when the page loads?
is there a way to extract or get the url of the webpage? how can i do that?
i tried: sImageName = CInt(Request("sImageName"))
but its not working.. it returned invalid string input
anyone?
thanks..

|

sImageName = Request.QueryString("sImageName"))
Always use request.querystring to get data from url.
Do good and have good.

I seem to recall using an ErrorProvider component back in the day with ASP.NET 1.1 has that been toasted to be replaced by the Validators or have I just gone blind or...? From what I recall it was pretty open to how it was used.
I need to do all validation at the server dynamically after post back because the errors come out of custom business objects and are localized for the user and can be complex and most importantly are already in place and working in a winform app and are not to be messed with.
Scneario: the user posts back, I move their input into the business object, the business object either says ok can save or it has broken rules which I can access and matchup to each control that has a broken rule (is invalid).
Can I then add a validator to the form for each broken rule populating it with my error message as appropriate and send that back to the user so they see the rule and the red invalid icon etc and can fix, repost and I can then check it all over again?

I usually handle validation in 2 ways in asp.net...
1. I always check for basic field format (i.e. is it a phone number, zip code, email, etc) using the asp.net validator controls (i tend to use the customvalidator one almost all the time as I have a validation javascript that I include). I usually put a validation summary at the top of my forms to display all these field format errors. These are just sanity checks.
2. For business logic validation that happens on the server, I include an asp.net label where I output the business logic error/s. So my form postsback and I run bl checks. If they fail, I set the label to visible and set it's text to the error and stop the processing (i.e. I don't call save for instance). The only tricky thing with the label is to make sure you set it to not visible if your bl passes, especially if you don't redirect after your save.
Usually I create an 'error' class in a stylesheet and set my label and validators to use it. Or skin the validators if you're in asp.net 2.
I also tend to use a home grown custom server control, my 'errorcontrol' that includes this label and the validation summary. And usually has a 'seterrortext' method on it. I use this to simplify some of it.
You could play with the 'server validate' part of the validator controls but they are typically (I believe) tied to a specific control and not well suited for overall (across controls) form validation.

Ok, cool, thank you.
That gives me some ideas.
The more and more I experiment with asp.net 2 the more I find it simpler to just bypass a lot of the built in functionality and components and do it myself.
Almost every new feature seems so tightly wired to a concept of using direct database access from the web page and editing nearly anything through some sort of grid like control that it's too much of a fight to work with it using custom business objects.
thanks again.

u can use google or baidu.com. there're more correct answers
for example:
string sql = string.Format("INSERT INTO Table(vl1, vl2) VALUES('{0}', '{1}')"
, txtbox1.Text
, txtbox2.Text
);
then defined sqlconnection,sqlcommand etc, open the sql database.
then u could be get the results of sql command

I have a treeview on my page and when I expand the node and click a child node it returns the page with the treeview colapsed. I want to keep the treeview in the state the user has it opened. Thanks for everyones help in solving my dilemna.
|
|
|
|
|
Could you be more specific about which treeview control are you using ( Microsoft TreeView or TreeView in .Net 2.0, or a third party control ...)? And what does your code look like?
|
|
|
|
|
You have to expand the node of the tree on next page using your code. You have to expand the node explicitly.
Do good and have good.

i'm trying to call GridView.Render() on a webform, but i always get an error saying "that i must place my control in a form with runat='server'" however am sure that my control is in a form and also set to runat server, i'm also sure that the GridView don't have any other asp.net child controls like checkbox added to it,
i just want to mention that it works fine in .NET 1.1 using datagrid or any other control but it don't work in .NET 2.0
so, is it a bug ? or i'm doing somethin wrong ?
well, i hope to find a solution
thanx in advance.

There is a slight difference in the .NET 2.0, you will need to override the Page.VerifyRenderingInServerForm method in the web page and simply return true.

that make sense
thank u very much

Do as the information page says, and you will se the error message instead of the information page.

Our web server runs out of memory every so many hours. We scheduled IIS restarts every 4 hours.
Any ideas on how we can figure out why the server runs out of memory so fast?
|
|
|
|
|
There are a couple of things that you may want to do:
+ Attach more RAMs 
+ Check the IIS configuration.
+ Investigate your code that may eat much of the memory.

You can't use it in .NET 1.1 or 1.0, but you can use a regular expression validator to validate your input.

Like Christian said, you can use the RegularExpression validator to validate the input textbox control, another option is that you can use a third party component that is available out there. You do it yourself and you need know javascript well enough.
