Passing A JavaScript Variable To A Helper Method?

Feb 24, 2011

I am using ASP.NET MVC 3 and the YUI library.I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such:

window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))';

Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like:

var formatActionLinks = function (oCell, oRecord, oColumn, oData) {
var newsId = oRecord.getData('NewsId');
oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>';
};

C# - Hidden Variable Vs Server Variable Accessing On Client Side In Javascript

Jul 14, 2010

I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.

I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:

var value = eval(<% =value %>);

Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().

Which is the best approach and what are the pros and cons?

Passing Variable From Event To Page_Load?

May 19, 2010

I am thinking this is a pretty simple problem... but I can not get it to function.I just want to get the calendar control to change a date which subsequently modifies a database select statement. I can get the current code to process without error, but the variable set is always a click earlier. Of course, I want the variable to be set upon any change in the calendar control.

public partial class NewBusinessReport : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

[code]...

Does this make sense? I just want it so that when SelectionChanged gets fired the Calendar1SelectCommandDate passes the correct date to the Page_Load page. The error I get now is:"The name 'Calendar1SelectCommandDate' does not exist in the current context"I get that the variable does not exist in the context. That actually seems to make sense based on what I have coded; however, I try to get that variable established and I still seem to be headed in the wrong direction.Basically, I have four calendar controls, one for a date (period 1 start, end and then period 2 start, end). I want to set the program so any change in that date sets off a new Select statement into the SQL server.

Web Forms :: Passing Value Of A Variable With URL Of The Hyperlink Control?

Sep 4, 2010

I have 10 hyperlink controls. Depending on which hyperlink is pressed I want to pass a value to the target page. I think the easiest way would be to pass the value using URL of the hyperlink controls. Something like <asp:HyperLink ID="HyperLink1" NavigateUrl="~/News.aspx?id=>. I can pass just a value, but I want to pass a value from a variable.

<asp:HyperLink ID="HyperLink1" runat="server"

SQL Server :: Passing A Variable To A Remote Stored Procedure?

Feb 27, 2011

I have a SQL stored procedure on a SQL server that uses a variable to create a new database. This works in SQL I have a connection string that works I have added a sqldatasource to a webform, and configured the datasource to connect to the remote SQL database and am able to select my stored procedure. I am able to bind the variable to a control in the sqldatasource wizard (often two of the same control appear- if that is significant)

When I test the sqldatasource in the configuration wizard and put in a manual entry, the procedure runs and works

It is on the web page I am having troubles. I want the user to enter a name in a text box, click a button/link, and run the procedure. Ive used buttons and links...but not in the right way I think, becuase when I click them the stored procedure doesnt run.

As mentioned above, I have selected the right control in the sqldatasource wizard. So what do I need to do now?

Is it button click event? If so whats the syntax?

Should I be embedding my textbox in a dataview?

How To Get The Value Of An .net Variable Into A Javascript Textbox

Nov 29, 2010

I'm writing some Javascript code for an ASP.net page. have the string "foo" assigned to a string variable myString.I would like to assign the value of myString to a JavaScript variable, so I write in my ASP.net code:

<script type='txt/javascript' language='javascript'>
var stringFromDotNet = '<%=myString%>';
</script>

This works fine as long as myString does not contain quotation marks or line-breaks, but as as soon as I try to assign something with quotation marks or line-breaks, all hell breaks loose and my code doesn't work.
