View 2 RepliesI have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.

return [variable1.text(), variable2.val(), variable2];}
I've searched for ways to call the javascript method from the web method but every time my search results in how to call a web method from javascript.
I did find this but it was done from the code-behind of a silverlight project and when I tried adding the correct reference to my code-behind it wasn't there
var result = HtmlPage.Window.Invoke("GetItems"); Is there a reference I'm missing?

i just want to be able to call a javascritp subroutine on the client, after the server has done its thing (when an action completes or control goes to the view, i'd dont mind calling the js from the view either).
for some reason, even vs2010 doesn't let me put breakpoints in <% ... %> tagged areas between <script...> and </script> tagged areas. i for this reason can't figure out whats going on and how it's running things. here is what i've put in my view, and the javascritp should run, but it doesn't....

Is it possible to fire a JavaScript method after a form element is considered invalid? Here is my scenario:
There are 2 tabs on the ASPX page. The user has to fill out info on both tabs. The user, while on tab 2 clicks the submit button. However, there is a required field on tab one that needs attention. Do I need to create a custom valuator (either a CustomValidator control or create a new control from the base valuator) to call a JavaScript function to display tab 1 and show where the error is?

View 2 RepliesAdding a label control inside of a div will short circuit my image buttons onClientClick method call.
I have an Asp.net panel control. In that markup I have an image button control. My image button when clicked will not call my Java Script method unless the image button control is wrapped with a div or table <td> tag.
That is fine with me. However Just to the left of my image button I have a label control that must be on the same line/row of my image button. If I wrap both the label control and image control in a div or td tag then
my Java Script method is not called. So somehow wrapping the label tag with a div or td results in the short
circuiting of calling my Java Script method.
Why is this? I must have my label and image button control on the same line, so that is the requirement.
I tired using a span tag instead of a div, but that does not work. Below is my Asp.net markup code.

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)

I want execute below callback() method after completion of document.getElementById('btnDownload').click(); method . Now callback()executing immediatly. I want wait "Click()" process done then Execute callback(); method.

callback();
}
function callback() {
this._popup = $find('mdlPopup');
// hide the popup
this._popup.hide();
alert("hi");
}
When this function is hit , it does not call my function in code behind? Why could it be doing this? How can I fix this error.
$(document).ready(function() {
$('[id$=btn_Update]').click(function() {
var reten = $('[id$=txt_Reten]').val();
var i=0;
var selectValues = "";
var ProdID = new Array();
$("#lst_ProdId option").each(function() {
selectValues = selectValues + $(this).text() + ",";
ProdID[i] = $(this).text();
i++;
});
for(var j=0; j < ProdID.length;j++)
{
// alert(ProdID[j]);
}
var params = "{'ProdID':'" + ProdID + "','RetenP':'" + reten + "'}";
$.ajax({
type: "POST",
url: "/ProductPricing/Products/RetenPeriod.aspx/UpdateRetenPeriod",
data: params,
contentType: "application/json; charset=utf-8",
datatype: "json",
success: function(result) {
alert("sucess");
},
error:function(e) {
alert(e.statusText);
// if(errorThrown != null)
// alert(textStatus+ ":"+errorThrown);
// else
// alert("fail");
}
});
return false;
});
return false;
});
This is my webmethod in code behind:
[WebMethod]
public static bool UpdateRetenPeriod(string[] ProdID,string RetenP)
{
for (int i = 0; i < ProdID.Length; i++)
{
update(ProdID[i],RetenP);
}
return true;
}

I have an asp.net mvc application that take a while to load on my production server. I would like to write a script to call my pages every 10 minutes to avoid the pages from being scrapped on the server, which would then cause the server to reload them.
I was thinking of using a SQL Server stored procedure to call my pages every 10 minutes to keep the pages alive.
I've read that I can do this using CLR, but I am not sure how. Does anyone have an example of how to call webpages in a SQL Stored Procedure using CLR?
