When 'return false' is fired, I'm assuming that the function is stopped at that point and there's no need for exit fors and things like that?
I'm new to C# and ASP and can't seem to figure out how to write a function to return a CSS Class name.
Here's what I have so far:
In "MyWeb.master" I have a line that reads:
<asp:HyperLink ID="HyperLink1" text="xxxxx"
cssClass='<%# MyCssStyle("ddd") %>'
NavigateUrl="http://www.RDRR.com/Catalog.aspx?TribeID=1"
runat="server" />
And in "MyWeb.master.cs" I have a routine within the partial class that reads:
public string MyCssStyle(string myInput)
{
myInput = "NavigationBarUnselected";
return myInput;
}
This code does not throw an error, but neither does it return a value. What have I missed?
I have this java function that works great, but I need it to only return two decimal places like 333.33. Currently it returns 333.3333333333. What can I do to modify this?

I have written an insert stored procedure which is called by my business logic layer, I want to return the new ID to the function once it has executed but i'm not sure how.
My SP uses RETURN SCOPE and when I have tested this it works but how I get that into a variable in the BLL function I don't know.
validation(ie if there is no matching value in TableB),i want to show a confirm dialog box asking the user if they want to add a new entry in TableB. If user says Yes then take him to another page to do the entry else stay on the same page I have added that validation in textchanged event of the textbox.
[Code]....
Here is the javascript
[Code]....
How do i capture the return value from the javascript and based on it send him to another page.
Without giving away specifics: basically, I have a bunch of users adding content to my site. What happens now is ajax sends the text to a web service which does its thing, sends the info to the DB, Sends the user an e-mail, and then returns a response to the browser to do something.
What I would like to do is change that order. I want to return a response to the browser so the user is not waiting on the e-mail to send before they get their response. Basically, I'm trying to gain every milisecond I can to quicken the response, and there's no reason for the user to wait for the server to send their e-mail before it tells them that everything worked ok. If the info went to the DB, that's all the user needs to know, they'll know the e-mail sent when it shows up in their inbox. I notice this is an issue on my local machine which has no SMTP server and can actually hang the page response up for a few extra seconds because it's throwing errors trying to send something with no SMTP server.
So, I know in my function when I say
[Code]....
it WORKS, but I want to send the e-mail after the return. Is there ANY way to get this to happen?
I am looking for a c# function to return a portion of the html. Say I have pages that render html of about 60 k in length, I want to email to users showing only the first 2k and add a link to the original page.
Sure there is a Substring function with String, but it will give me a lot of unclosed html tags.
I trying to display image in picture box. The application have two part.First part is windows application, and second part is web service (asmx).This is the code for windows application:
Public Sub PrikazSlike()
Dim p As localhost.Service1 = New localhost.Service1()
PictureBox1.Image = Image.FromStream(p.PictureShow()) [code]....
The problem is that function in web service does not return System.IO.MemoryStream data type so I getting error message can not convert:
Error 1 Value of type 'WindowsApplication1.localhost.MemoryStream' cannot be converted to 'System.IO.Stream'.
I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.

ASP.NET 3.5 C# I am joining two tables using Linq. Table names are MapAssets and ExitPoint. In Database they are related with 'has a relationship'
I am writing a function in my BLL to return the joined table
public List<ExitPoints> GetExitPointDetailsByProjectID(int iProjectID)
{
ctx = new CoreDBDataContext();
var exitPointDetails = from ma in ctx.MapAssets
join ep in ctx.ExitPoints
on ma.MapAssetID equals ep.MapAssetID
where ma.ProjectID == iProjectID
select new
{
//would like to have data from both tables here
ctx.MapAssets,
ctx.ExitPoints
};
return exitPointDetails.ToList();
}
This obviuosly doesn't work. And I dont know what to return at all. All constraint I have for the return is to be able to be bound to a gridview. is this the correct way? Or else whats the correct way?
I added the button attribute on page load.

What I want to do is if the OK button is clicked, save the data and then open the grid. If the Cancel button is clicked, open the grid. The problem is when I clicked the Cancel button, it didn't do anything in the OpenGridButton_Click event.
