How To Add Code / To Use LtlBranch As My Lookup Variable?
May 19, 2010
I have a site which I need to modify and add phone numbers based on what branch is being displayed. I have NO clue what-so-ever on how to do this.I have a .aspx file which is using another file as its code behind. My first question is: If I want to add "if statements" into this code, do I add them in the .aspx file or the code behind (aspx.vb) file? Next question is: A statement like
"<asp:Literal runat="server" ID="ltlBranch" /> Employees"
is using ltlBranch to place the branch name in front of Employees. Can I use ltlBranch as my lookup variable? In other words, is this valid coding for asp?
If ltlBranch="MainStreet"
show the rest of my code[code]...
Should I be creating a sub-routine within the codebehind form and then calling that routine? I am clueless on how to go about this, and am just trying to get a starting point so I can look up more info on it.
I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.
I have a page with a Textbox, a Button and a Label control. On Button_Click event , I store the value of Textbox in a variable called S using code behind.
I want to show the value of S in the Lable control using inline code but not using the code behind. ?
I have a gridview that when users click an asp:Button a confirmation box needs to appear. Inside that confirmation box, I want to include information from the gridview (DataKeyValues) that I can use in the codebehind to customize the confirmation message that pops up.
I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place? <p> <%for (int i = 0; i < 30; i++) {
I'm having a bit of difficulty setting a variable from the code behind and utilising it in the ASP.NET page (setting it as the value inside a textbox). My webpage simply errors and says it does not exist in the current context. The variable is declared and set all in the Page_Load method.
Here is the relevant ASP.NET code. I assume you will not need to see the code behind, as I have tested outputting the variable via the codebehind (using Response.Write) and that works fine.
for(var i=0; i<<%=Model.Mydatalist.Count%>;i++) { //then I need to pass i to Mydatalist like Model.Mydatalist[i] } //var myJSdata="<%Model.Mydatalist["&i&"]%>";
is not working.. as system see i (i's value) as a string, and will throw exception: cannot convert string to int.
I guess I'm missing something here, but I can't find a way to pass a simple variable from my code behind file to the .aspx page. In code behind I have:
Dim test As String = "test" and in my aspx page I try: <%=test %> that gives me the following error: Error 2 'test' is not declared. It may be inaccessible due to its protection level
I'm looking at a routine that returns a variable name and value in two fields from a table, the intent is to then assign the value to the correct variable.
How to register a Java Script varibale in Server Side (Code behind ) and access at Client side (Javascript file ) , without a hiddenfield , Literal etc
I'm making a page with a DropDownList (called ddlSupp) that contains several suppliers, and I populate it with an SqlDataSource, all in front code.
In another part of the page I make a CheckBoxList, and populate it again with an SqlDataSource. The select command of the SqlDataSource is a procedure call to my MySQL database. However, what the CheckBoxList gets populated with depends on who is selected in ddlSupp. How do I make a variable in front code that will take the value from ddlSupp and populate my checkbox accordingly?
Here is my code:
[Code]....
I get a MySQL error at (<%$ddlSupp.SelectedValue %>) so I know the wrong value is being passed into the query. How can I fix this?
How can I call a .net method in inline code using a javascript variable?My code looks like this:
for ( var i = 0; i < numberIterations; i++ ) { var result = <%# GetFilterTagURL( myArray[i].Value, false) %>; //do stuff with result }
This block is inside a javascript block; the GetFilterTagURL method is a a .net method and I want to pass the variable myArray[i].Value as the first parameter.
UPDATE:I guess that, as you say, I'll have to create a web service to achieve what I want.
I have a problem to pass along public variables from C# code to the HTML code. I assign the variables in the Page_Load event and then pass along them to the Panel and Image control in the HTML code. Though I get this compileerror for the Width: "Cannot create an object of type "System.Web.UI.EbControls.Unit" from its string representation '<%setWidthImage%>' for the 'Width' property."
I'd like to know how to declare a variable in my code behind page that I can use in all the subs of my code behind.
I tried in after the Partial Class declaration to declare a "Public String" :
[Code]....
and to use it in my subs but when I use it from a sub to another I loose the value affected in another sub.
Is there a way to use a Public variable from a sub to another (I'm actually using a session variable in order to do it and I'm not sure it is the best way)
tually through some piece of code I am getting a double variable's value. see my code below.
[Code]....
I declare double totalPerdiem = 0; globly. I dont know that how many times this event would fire in a session.I want this like if first time the code runs and give a value to totalPerdiem, it should keep aside and if event comes again, then this value should added to the old one
I've done a search and read a few things, All i'm trying to do is set a variable in the code file and call it in the page file asp.net vb.net 3.5. I've tried like this in the code file:
[Code]....
And in the design part of the page:
[Code]....
But it says that name isn't declaired. What am I doing wrong?
This works. Now I have to submit a form via C# code.... DONE. It works. And my C# code saves the "new" HTML to a string variable called "submitParsedHTML". My question is: how to I change out the URL, to go through the string variable instead? I am thinking about doing this: When the user clicks the button to "Post" to the form and the app grabs the HTML. The app logs into my FTP account and saves the HTML as a seperate (temporary) file to be used on the internet [URL] Then the app can then parse the HTML as if it was a normal HTML document and not have to go through formatting the text to an HTML document. What do you all think?
I have a control and list of variables and I want in the control property to be assigned to the variable value directly in the page not from the back code, something like this
My global variables
public string Banana = "banana_pie"; public string Apple = "apple_pie";
in my custom control instead of:
<uc:LoadPie id="pieBanana" type="banana_pie" />
To this
<uc:LoadPie id="pieBanana" type="<%=Banana %>" />
so is there a way or just assign the property in page back code.
