I have alot of query strings on one of my seartch pages. The problem is that even if the corsponding setting is not set by the enduser it will be visible in the URL. Is there a way to avoid this?
In this case the Controller actions take an object of the following class :
[Code]....
Is it possible to avoid setting all the values in the URL when it is the default values that are used?
I'm used to using VB.net for web programming.Often, I have something like:
Dim s as string = Session("s")
I get a string value for s from the web session. If there is no value in the web session, I get a blank string.However, AFAIK, in C#, I have to have something like the code below to do the same thing.
string s;
try { s = Session["s"].ToString(); }
catch { s = ""; }
I'm pretty new to C# and ASP.NET, so bear with me on this one. I'm setting up a page that receives query strings from the url. It then passes these strings to another method (in another class, actually), which goes on to do lots of things depending on the value of the query string.
The general structure looks something like this, where DoSomething() is actually part of another class that will be used by lots of different pages:
pretected void Page_Load (object sender, EventArgs e)
{
DoSomething (Request.QueryString["name"]);
}
public void DoSomething (string UrlVariable)
{
// if UrlVariable isn't set, initialize it to some value
// do stuff with UrlVariable
}
Here's what I'm wondering:
If the query string "name" isn't defined in the url, what does Request.QueryString return? an empty string? null? If it returns null, what happens if I try to pass null to a method that is expecting a string? Does the whole program fall apart, or can I check for null inside the DoSomething() method (after receiving the null string)?
The "name" is optional, so if the user doesn't set it, I'd like to detect that and initialize it to some default value. If possible, though, I'd like to put any validation inside DoSomething(), instead of doing the check on every page that requests the string.
I can get the current value of a URL query string by using Request.QueryString["UrlKey"], but can I actually modify the URL with code, without doing a form GET submission?
If the user is landing on the page for the first time, what is the easiest way to programmatically create the ?UrlKey=value through the Page_load method? Or am I better of doing this with Javascript or building a redirect Like: string redirect = "www.mysite.com?" + MyKey + "=" + MyValue;
I'm completely lost as how to resolve this issue, I'm not sure if it's occurring in iis or it's my .net

I am currently using a number of query string parameters to pass some data from one page to a second page (the parameters hold confirmation/error messages to display in the second page), that due to a third party product can no longer work correctly in the production environment. The user completes an action on the first page, and is then transferred to the second page. What are the possible alternatives to use instead of a query string and GET - session variables, POST data, or something completely different?
View 3 RepliesI am using the datanavigateurlformatstring within a datagrid property with the property set something like;
editrecords2.aspx?RID={0}&SID={1}&LID={2}&DIP={3}&IID={4}&TID{5}
Unfortunately, when the new webpage opens, the url contains lots of spaces and I'm struggling to remove all of the spaces. The code actually works but looks a bit messy, see below.
"http://localhost:34354/website1/editrecords2.aspx?rid=2&sid=2& dip=5 & iid=3 &tid=3"
but should look like this
"http://localhost:34354/website1/editrecords2.aspx?rid=2&sid=2&dip=5& iid=3&tid=3"
i have i doubt. any body clarify this doubts. Find biggest character in a string. using ascii values.
View 3 RepliesI've sucefully created a method to insert values through EF, but i've a question (maybe, a newbie question).
Should i send the values to be inserted as strings to the DAL, and then i create the object there or should i create the object in View Layer and then send him to DAL?
Example 1 (DAL):
[Code]....
Example 1 (View Layer, on a click button for example):
[Code]....
Or should i receive the strings in DAL like this: public bool NoticiasInsert(string tituloPT, string tituloEN, string descricaoPT, string descricaoEN)
Then i create the object cdcModel.noticias and set the fields there with the strings values.
What do you advice me to do? I know that both ways works, but i'm trying to develope with better patterns (i don't know if this is the exacly word, sorry my bad english)
cdcModel.noticias campos = new cdcModel.noticias();
campos.tituloPT = "a";
campos.tituloEN = "b";
campos.descricaoPT = "a";
campos.descricaoEN = "a";
if (DAL.NoticiasInsert(campos)

View 3 RepliesI have a SQL query I'm running in an ASP.NET page. The final parsed SQL needs to contain a list of string values in the WHERE [columnname] IN [values] format. For example, the final query might look something like this:
SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN ('ABC','DEF','GHI','JKL', /* etc */);
However, the string values in the WHERE clause need to be dynamic. Normally I use parametrized queries to make my code convenient and safe, so conceptually I'd like to do something like this:
String[] productCodes = { "ABC", "DEF", "GHI", "JKL" };
SqlCommand cmd = "SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN (@ProductCodes)";
cmd.Parameters.Add("@ProductCodes", productCodes);
However, this sort of functionality doesn't appear to exist in .NET. How should I go about implementing this? I could use a foreach loop on the array and run a query with a single value as a parameter for each value, but there could potentially be a hundred or so different values in the array and it seems like querying them separately would be very inefficient.
I've read another question where someone suggested a solution for strongly-typed int parameters, but that method would make me nervous about SQL injection when used with String values, especially since the client may very well be able to influence the input values.
How would you implement this query functionality?
EDIT with DB Details:
The database is SQL Server 2005.
I have a repository function called getList which retrieves certain information that gets posted to it from a form. My form has 6 fields, and a user can enter searvh criteria in any or all the fields. According to what he has entered, I must execute a SQL string to retrieve matching information.
I have the following:
[Code]....
But, if a user enters only a surname, my query will return no results. Is there a way format my sql string to allow default values, or maybe build the sql string at runtime. In MS-SQL it was easy to do, but how would one do it in LINQ??
How can I get the following default culture values defined in the Web.Config:

I am not looking for the current culture. I am looking for the default ones on the Web.Config as showed.
I've been getting "Connection forcibly closed" errors and in researching a resolution, I have seen to with the following web.config options, which currently are not set in my web app.
Before I change them, I'd like to know what they are currently set to.
how to read these values from .NET code, preferably VB.NET, though C# is fine.
<httpRuntime
executionTimeout="90"
maxRequestLength="4096"
useFullyQualifiedRedirectUrl="false"

minLocalRequestFreeThreads="4"

When I make a routing rule like
routes.MapRoute(
"Rule",
"Home_{action}/{id}",
new { controller = "Home", action = "Index", id="" }
);
"Home_MyAction" works (no id here). But with
routes.MapRoute(
"Rule",
"Home_{action}_{id}",
new { controller = "Home", action = "Index", id="" }
);
"Home_MyAction_" doesn't work (404 error).
Why is it so?

View 3 RepliesI have a user input form with a cascading dropdown. The code is:
[Code]....
Once the user submits the form, it goes into a temporary table, pending admin approval. On the approval page, I display a GridView of all pending records. Is it possible to use a CascadingDropDown in the GridView, with each Dropdown set to the value stored in the database for that specific record?
If I can't do this with a gridview, how about a dynamic ASP table?
I'm creating user controls that i will put into an update panel and make them visible only when required using triggers. Once visible it will float in a dialog box so it has a close button which will just hide the control on client side.
The controls have multiple post back states, like a wizard, i'm using a multi view control to accomplish that. My problem is that once the user is at step number two in the control, if the user closes the dialog, than opens the dialog again, (note that the control is made visible on the server and reloaded by updating the updatepanel) the second step will still be displayed. The reason is . because whenever there is a postback the control will load its state using the viewstate, even if EnableViewState is false it will still load it using the LoadControlState method. so my quesion is how can i force a user control to load fresh with its default values without any postback data.
