Javascript - Callback Function With Parameters
Jan 4, 2011I'm using AJAX Page Methods, but I can't seem to be able to pass the needed parameters:
function getFavStatus() {
//favs is a list of DOM <imgs> that I want to modify their img.src attribute
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt,setFavImg(favs[i]));
}
}
function setFavImg(fav, response) {
fav.src = response;
}
The problem that I can't figure out is how to use the "response" from PageMethods, AND pass the DOM object to the callback function.
I've also tried doing something like this:
function getFavStatus() {
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt, function (response) {
favs[i].src = response;});
);
}
}
In this case, the response works properly, but i is always > favs.length, because it has already iterated through the loop... Edit: My PageMethods.isFavorite signature is: [System.Web.Services.WebMethod] public static string isFavorite ( string p_id )

View 4 RepliesAJAX :: Recover Parameter In Callback Function
Jan 15, 2011I'm using ajax to call a webmethod from javascript. The call is successfully made to the webmethod but I'm not able to access the parameters I passed to the webmethod inside of the "OnSucceeded" callback method. I need access to those params because I need to perform more tasks on the client side when the webmethod returns. I'm assuming that the params are returned inside "usercontext", but the value of that param is "null" How can I have access to those params?
Here my sample code:
function OnSucceeded(result, usercontext , methodName)
{
alert( result + ' The value of usercontext is: ' + usercontext);
}
function OnFailed(error, userContext, methodName)
{
alert('Attempt to delete semantic attribute from page failed!');

function deleteSemanticAttribute()
{
var username = 'xxxxxx';
var password = 'yyyyyy'
PageMethods.GetMyData(username, password, OnSucceeded,OnFailed);
}

Send Multiple Parameters Via Querystring Asp
Mar 5, 2010Which is the best way (in performance and security) to send multiple parameters to a web page (on a different server), considering that the length of the parameters may vary because I'm sending a list of products, and the customer may have selected more than one product, so we need to send each product on the querystring to the other page. For example (I'm on C#); I want to call a web page like this:
Simple Querystring: thepage.asp?Product=1&Name=Coffee&Value=1.99
Json: thepage.asp?{"Product":"1","Name":"Coffee","Value":"1.99"}
XML: thepage.aps?<xml><Products><product>1</product><name>Coffee</name><Value>1.99</Value></Products>
(Obviouly considering we can't send special characters via querystring, but I put them here for better understanding) Which will be the better way (performance, security)?

C# - Send Parameters Into Dynamically Loaded User Controls
Sep 19, 2010I load the content of some User Controls into my page with the use of jQuery. So I have this function that extracts the content from my User Control, and it works like a charm.
public string GetObjectHtml(string pathToControl)
{
// Create instance of the page control
Page page = new Page();
// Create instance of the user control
UserControl userControl = (UserControl)page.LoadControl(pathToControl);
//Disabled ViewState- If required
userControl.EnableViewState = false;
//Form control is mandatory on page control to process User Controls
HtmlForm form = new HtmlForm();
//Add user control to the form
form.Controls.Add(userControl);
//Add form to the page
page.Controls.Add(form);
//Write the control Html to text writer
StringWriter textWriter = new StringWriter();
//execute page on server
HttpContext.Current.Server.Execute(page, textWriter, false);
// Clean up code and return html
string html = CleanHtml(textWriter.ToString());
return html;
}
But I would really like to send in some parameters into my User Control when I create it. Is this possible, and how can i do that?
I can see that LoadControl() can take some parameters with object[] parameters but im really not sure on how to use it.

It works but when I'm trying to enter in TextBoxSearch by other language at the other side in my page load of good.aspx I'll get parameters using Request.QueryString["key"] it gives me like this "?????? ???? ????".
That's interesting when I copy and paste text into TextBoxSearch at result it works good at the Goods.aspx Pageload event.
Do AJAX Callback Before Each Postback For Webforms?
Oct 6, 2010Whenever a postback would occur (AJAX'ed by an UpdatePanel) I want to do a callback beforehand and only after the callback has completed (either successfully or not) should the postback occur. How can I do this?
Elaborate explanation: We use ASP.NET AJAX (UpdatePanel 'n stuff) together with DevExpress controls. Among those controls is the ubiquitous GridView. As is typical with ASP.NET gridviews, you can edit rows one-by-one, and to save your changes you have to hit the "update" button at the end of the row. However if you make some changes to the row, then forget to press the "update" button, and hit something else in the page (say the big red SAVE button that causes a postback and saves the whole form to the DB), your changes will be lost. The row will still be in edit mode, but it will have reset to the data it had initially when you started the edit.
Our clients are not happy with this and want the row to be saved automatically if the user forgets to do so himself. Luckily the DevExpress gridview is smart enough to have an "Update()" method which I can call from JavaScript. Unluckily that causes a callback and returns immediately. If I allow the postback to continue as normally, the callback will get aborted. Well, technically it's a race condition I guess, but so far it seems that the postback wins. There are events to which I could attach for success/failure of the callback, but I don't know how to "resume" the postback that started it all. We could turn off callbacks for all the grids, but that would be a performance disaster.
Call SQL Function With Multiple Parameters From C# Web Page?
Mar 30, 2010I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this:
String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE
ClientID = @ClientID AND LocationName = @LocationName ',10)";
SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection);
Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID
Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default";
// Real code uses Location Name from user input
SqlDataReader reader = Cmd.ExecuteReader();
When I do this, I get the following code from SQL profiler:
exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable
(''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)',
N'@ClientID int,@LocationID nvarchar(20)',
@ClientID=7,@LocationName=N'Default'
When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists.
exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20);
SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable
(''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)',
N'@ClientID int,@LocationName nvarchar(20)',
@ClientID=7,@LocationName=N'Default'
I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function.
Web Forms :: Passing Multiple Parameters To VB.net Function

Text='<%# FormatFooter(Eval("Anonymous"), Eval("DisplayName"), Eval("CreatedDate")) + "

The Function "FormatFooter", needs to pass in Anonymous and DisplayName parameters. Anyone know the correct syntax for doing this?
