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.
I am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here
I'm at a loss, this is the first time I have seen these problems occur.
I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.
I want to add a class to a div inside my repeater control based on whether the query string value is true or false, so that I can style it differently.
View 6 RepliesI have a hyperlink column. I need to add just one query string to the url. It needs to pass the string located in the first column of the same row. Let me know if you need more info. Edit: Also, if you don't mind it might be useful if I was able to pass the primary key of the object bound to that row, instead of the string in the first column. Would that be tricky to do? Either would work fine.
View 1 Replieshow do i add a new parameter to an existing query string?
[URL]
now i need to add a new parameter say, showsearch.
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
Is It Possible to send a string consists of (,.&') in a query string ?

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>");
I have some code that splits a session into strings by a -
My session looks something like this 123-456-789- and I split it like this
Dim MyString As String() = Session("MySession").Split("-"C)
And i've got a some code like this
Dim x as Integer
For x = 0 to MyString - 1
Response.write("Ref: " & MyString(x) & "<br>")
Next
This writes the code like this
Ref: 123
Ref: 456
Ref: 789
Ref:
So it's adding an extra Ref where it shouldn't be because there is no data after the last -
Is there a way to stop this adding in the extra one?
I 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 have a website built that uses master page templates. In the master page I have a simple menu in a list. This is not dynamic (yet!).
I am trying to put together some code behind to write a simple css class to one of the menu links if the Request.ServerVariables("URL") is equal to the current page URL
I have no code written because everything complains when I try to come up with something. I was thinking of doing it using a switch function but am I over complicating things?Below is the simple menu with the class I am trying to write to the link:
<div id="nav">
<ul>
<li><a class="selected" href="Default.aspx" title=""></li>
<li><a href="" title="ThisPage.aspx"></li> [code]....
I want to dynamically add the value of query string, taking inputs from the database and thus building a link. I want this to work in an ASPX page.
Here is the snippet of what I want to achieve:
<asp:HyperLink NavigateUrl=""></asp:HyperLink>
Here I want to dynamically build the value of NavigatUrl, I tried doing this;
<asp:HyperLink NavigateUrl="Welcome.aspx?q=" + <%= Value From My Code Behind %>></asp:HyperLink>
However, this doesn't seem to work properly.

I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.
I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?
I am new to ASP.NET And I am have THE hardest time understanding how to work with forms in ASP.NET. Here's what I am doing:
Dynamically add User Controls to a PlaceHolder based on some int value (which currently is passed in a HiddenField).Fire an event if the WebControls inside of the User Control change, then handle that event in the Main Page (i.e. save the input to DB)When the user clicks the "Next/Continue" button, the next controls for the next page are loaded. And I guess maybe I just can't seem to get how things work in ASP.NET, because I am really struggling with the general idea of how ASP.NET flows.
Should I be dynamically loading the controls in Page_Init, or Page_Load? Or should I load the controls when the buttonclick event is fired?Do I have to add the axCtrl.OnDataChange += new EventHandler(HandleAxControlDataChange); line on Page_Load? Or should I put this in When I first load the UserControl, I need to initialize some WebControls within the UserContorl. Is there a way to know if I have loaded new user controls into my placeholder? I can't use Page.IsPostback, because after the first page, every page is a postback from the buttonclick.

I am creating an application which creates pages dynamically, therefore all controls are also created this way. Initially adding a Editor part to the editorZone loads fine, as follows:

Where am I doing wrong here?
I am working on an application, where a user will enter their primary information (Name, Address, Email, Phone etc), then enter their automobile information (usually a fleet of automobiles).
My web page currently has one row of text boxes (Car Make, Year, Model, VIN, Mileage, License Plate)
Below this is a button called "Add More Cars"
What I am trying to do here is allow the user to add more cars if they have more than one that needs to be registered.
My problem is how do I do this dynamically?
2nd problem, how do I collect the data entered by the user (for all cars), to be able to write them to the database?
I have a gridview databound to an sql source returning about 1300 records (cars). I have listboxes to narrow the search (model year, manufacturer, segment). What is the most efficient way to tie these listbox selections to the gridview query?
Right now I am piecing together my own sql query string and replacing the SelectCommand. This works, but I keep running into timing issues where the command reverts back to the coded initial value. I can continue debugging this, but is there a better way?
I am using Wizard control, my requirement is when drop down list selected index change event occurs , based on the selected item I should remove or disable some side bar links. I have seen many posts removing and adding dynamically. But I could able to remove dynamically but I could not able to add dynamically. I am getting Viewstate problem.
