I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?

I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired please.
My demo page: http://bit.ly/92RYvq
Below is my code and the order I need it to fire.
[WebMethod]
public CascadingDropDownNameValue[] GetSubCats1(string knownCategoryValues, string category)
{
StringDictionary kv = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues); [Code]....

I have a gridview where the dropdownlist is built during the RowDataBound event. I need to be able to poup a window based on the selection from the dropdownlist Items.
I cannot use Repsonse.Write("window.open('link');") coz i will need to redirect to the webpage which clears out the search on the page.
I need to be able to open a new window with the link and continue executing code on the page.
I have tried,
1) Page.ClientScript.RegisterStartupScript(Me.GetType(), "openwindow", "window.open('" & link & "');", True)
2) Dim s As System.Windows.Forms.HtmlWindow s.Document.Window.Open(link, "", "", False)
3) Process.Start(link) - this works locally but dosent on the testbox

I have an application where I have a dropdownlist with AppendDataBoundItems set to true. This allows me to add a select all ListItem with a value of "-1". I store the selected value in a session so that the selected value is retained if a user navigates away from the page then returns. This works fine for all values except for when the value is set to the appenddatabound item (All). When I debug i can see that the onselectindexchanged event does not fire when the 'All' item is selected. If a user navigates away from the page and comes back this 'All' value is lost as it is not stored in the session.
find my code below:
<asp:DropDownList ID="ddlTeams" runat="server"
DataSourceID="odsTeams" DataTextField="Team_Name" cssClass="ddl"
DataValueField="TeamID" AutoPostBack="True" AppendDataBoundItems="True"
onselectedindexchanged="ddlTeams_SelectedIndexChanged">

I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

<asp:DropDownList ID="fiscal" runat="server" AutoPostBack="True"
DataSourceID="SqlDataSource3" DataTextField="fiscalno"
DataValueField="fiscalno" style="margin-left: 28px" Width="130px"

I get this error "The server method xxx timed out." calling a WebService that internally does a hard query to the database, and takes some time. I use this method to change the webservice timeout, but it does not seems to do anything (the timeout errors appears in less than a second).

I have a list of items in a GridView, with one column I'd like editable through a DropDownList.I do not wish to put the GridView into 'edit' mode or have any 'confirm/update/save' buttons.. I just want autopostback on the DDL, and an OnSelectedIndexChangedevent to update the row.Problem is, from my OnSelectedIndexChangedevent within the DDL, although I can see the new value to save, I can't discover the row to update from the GridView.Can anyone see how I can achieve what I wish? Other than perhaps storing the row id within the DDL? Maybe turn it around so the GridView's events are called?

How would I get the previous item on DropDownList before OnSelectedIndexChanged fires the event?
I had a DropDownList that has names as its items ("John", "Mark"). By default the SelectedIndex is "John". Upon changing its index and selecting "Mark" the event OnSelectedIndexChanged will be triggered. When I use ddlName.SelectedIndex it will return only the index for "Mark" which I want to get is the index of "John".

I have the following method in a class withing a website.
public static void Authorise(int role, Page callingPage)
{
callingPage.Master.FindControl("divUnauthorised").Visible = true;
callingPage.Master.FindControl("ContentPlaceHolder2").Visible = false;
}
Now this works fine but I really want to just have the one parameter of role and not require the page to pass itself into the method. Is there a way of finding the object that called the method and casting it to a System.Web.UI.Page?
