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."

View 9 RepliesI'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)
I have a function that gets the position of a control.
[Code]....
All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:
function (getPosition)
{ var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>');
getPos(txtBox1);
}
I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.

View 3 RepliesI don't know if this is even possible, but here goes: I have an ASP.NET page that contains an IFrame that calls an HTML page. Is it possible to pass a variable from the ASP.NET page to the HTML within the IFrame? More specifically, I'd like for the ASP.NET page to fill in one of the fields on the form within the HTML page.
View 2 Repliesfor(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 have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
I have successfully been able to parse HTML from a website:
TestParser parser = new TestParser [URL]
List<Pairing> pairings = parser.ParsePairings();
DBSave.SavePairings(pairings, userID);
----------
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?

Can someone explain to me the rules around what can and cannot be evaluated/inserted into markup using the <%# %> and <%= %> tags in asp.net?When I first discovered I could inject code-behind variables into mark-up using <%= I thought 'great'. Then I discovered that if such tags are present you can then not add to the controls collection of the page (that's a whole different question!). But <%# tags are ok.
Is there a way I can inject a code-behind variable or function evaluation into the page using <%# ?

View 1 RepliesIn my example below I am trying to Bind 2 different size GoogleAds to the 2 first rows in the GridView. One Ad on each row. The ads that are inside.......
(i2 == 0) and(i2 == 1).
I need to use <%if (Counts < 2) %> in HTML to restrict it to just 2 Rows, so this variable needs to be passed correctly also. As it is now, Counts is not passed correctly so <%if (Counts < 5) %> needs to be set in order to see any ads at all. I beleive this is because Page.DataBind() is binding the last ad in memory from the loop.
So when running this code, the same ad (i2== 2) is set to 3 rows in the GridView. This is my problem!

I have a gridview that is dynamically created and have finished all but one problem - I need for my code that is within a Public Shared Function to access a textbox string - In the below I need myinput to return the string so that my query's can use the variable - the below shows: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
If I remove the "Shared" the error goes away however it crashes other parts. (if I hard code the text then all works as expected)
