I need to dynamically construct a url by appending new parameter to the current url.
I know how to do this in the long way by getting the current url and check if there is any QueryString, if no add "?" if yes add "&". Also check is the parameter is already exist. If yes change the value.
But is there any build in .NET function to do this? Like Request.QueryString.Add
I'm constructing a query using linq, but I'm having trouble using a collection, i.e. where field in database = anything in the collection.
Below is an example of what I mean:
dim keywords as string ="test,test2,test3,cats,dogs,frogs"
Dim getKeywords = (From cp In myDataContext.pages
Where cp.pageKeywords = currentPageKeywords.Split(",")
The aim of the above code is to return all records where the "pageKeywords" field contains 1st keyword, or 2nd keyword, or 3rd keyword etc.
I am trying to implement admin login and operators(india,australia,america) login, now operator id starts with 'IND123' 'AUS123' and 'AM123'
when operator india logs in he can see the details of only members have id 'IND%', the same applies for an australian and american users
and when admin logs in he can see details of members with id 'IND%' or 'AUS%' or 'AM%'
i have a table which defines the role i.e admin or operator and their prefix(IND,AUS respectively)
In loginpage i created a session for Role and prefix
PREFIX = myReader["Prefix"].ToString();
Session["LoginRole"] = myReader["Role"].ToString();
Session["LoginPrefix"] = String.Concat(PREFIX + "%"); works fine
In main page(after login) i have to count the number of member so i wrote
string prefix = Session["LoginPrefix"].ToString();
string role = Session["LoginRole"].ToString();
if (role.Equals("ADMIN"))
StrMemberId = "select count(*) from MemberList";
else
StrMemberId = "select count(*) from MemberList where MemberID like '"+prefix+"'";
Problem: 1. i want to constructor parameter something like
StrMemberId = "select count(*) from MemberList where MemberID like '@prefix+'";
myCommd.Parameters.AddWithValue("@prefix", prefix);
Which is not working
2 Displaying the members in gridview i need to give condition (something like if (role.Equals("ADMIN")) show all members else show member depending on the operator prefix)the list of members in operator mode and admin mode. - where to put the condition in gridview how to apply these
I need to implement a search page where a user will be able to specify some search criteria and perform a search. It's a requirement that the results are displayed on the same page, beneath the search criteria.
Here's the code for the controller class:
[Code]....
For simplicity, the table string above is hard coded but would be constructed dynamically in the real code.
I also have the following form defined In the body of my html:
[Code]....
Finally, I'm using JQuery to hijack the submission of the form and to request the html for the table:
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$("form[action$='GetTableData']").submit(function() {
$.post($(this).attr("action"), $(this).serialize(), function(response) {
$("#tablePanel").html(response);
});
return false;
});
})
</script>
I'm fairly new to ASP.NET and MVC but the thing that slightly bothers me is that the html is generated in the code-behind for the view.
Is there some way that qury string variables can be added dynamically ? Suppose Page one.aspx?Id=3 redirect me to Two.aspx
Can I add some parameters in Two.aspx before page loads ? I know query string collection is read only and it looks not possible but just asking there may be some way to do this.
Example:
[URL]
I added the iis tag because I am guessing it also depends on what server technology you use?
I m facing some problem. i m not passing Dynamic string through query string..
I m using this code
string abc = "CPCB_" + TextBox1.Text + "_" + TextBox2.Text;
Response.Write("<script>window.open('xml.aspx?Flag=3&date='+abc,target='new');</script>");
Is It Possible to send a string consists of (,.&') in a query string ?
View 7 RepliesI have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
View 2 RepliesI am wondering if you might be able to with a little problem.I am trying to learn more about building web services by constructing one but I have run into what I think is a syntax problem that I can't figure out. Below is my C# code:
[Code]....
I have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)
I am discovering the PrimaryKey columns names from within a loop, ie:
For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields 'fld.Name ' this is where the column name is stored, so I have to get this into an array Next I can not use this syntax.
GridView.DataKeyNames = new string() { "PowRatHP", "Voltage", "Phases", "Poles", "Drive" }
So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?
I wanted to create a URL like http://localhost/menu.aspx/?id so that on typing this, it displays all the id's in the database. for eg:134
123
543
234
may be the id's which should be displayed after fetching from the database. However, it should be displayed as it it is without any control or without arranging in any gird etc. How can that be done?

View 11 RepliesIn IE 7, I can right click on my page and select properties and (usually) see the query string that was passed to that page.
How do I see this in FireFox? I am having a bug where I should be passing consecutive numbers in the query string, such as deal_ik=1,2,3,4,5 etc but 5 is missing. So I want to examine the query string that is actually getting passed.

Is there a difference between me using JavaScript to redirect to URL + "?Querystring=value" versus using whatever mechanism ASP.NET uses?
If there is a difference, how can I make the rendered ASP.NET page be submitted to the same URL with a different query string by JavaScript?
I am developing a web application using the traditional Web Forms model. I have one page that loads the details of a particular destination. The url comes in the following format [URL]. I understand that this is not properly favored when it comes to search engines. what I need is something like this [URL]. How can I get this kind of functionality through web forms.
View 9 RepliesI am curious if is out-of-date to use query string for id. We have webapp running on Net 2.0. When we display detail of something (can be product) we use query string like this : [URL]We use query string for reason that user can save the link somewhere and come back any time later. I suppose that we use url rewriting soon or later but in mean time I would like to know your opinion.
