Web Forms :: Receiving WebService In Javascript Function?
Jan 4, 2011
I wrote a webservice that returns an array of Strings. Below is the code for the webservice:
WebMethod()> _
Public Function CheckNotices(ByVal UserId As String) As String()
' Dim time As String = Now.Date.ToString
Dim dt As New DataTable
Dim ob As New BLL.ClsBLL
I am working on windows Mobile 6. I have created Mobile Application which is receiving data from webservice. Web service is working on Development End and also in UK on Mobile Device. Same application is tried from Dubai to recieve same data but an error occured to receive data. What could be problem? Application from Dubai is accessing My PC service but server at Germany is not accessible. Is there ant blockage issue from server to specific Global IP. User is accesing using Wi Fi.
When I made an AJAX call to an ASP.NET page, I had a mechanism to return some text based on QueryString parameters. Such as :
Response.Write("<text>");
But in the response, I got a lot of extra information about viewstate status. This does not happen in classic ASP or PHP. Also if I ask for the whole page, it returns it with the page directive
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" > hi ihave this functin in .vb file Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click end sub
I deployed one webservice which calls function which going take more than 5 -6 hours. I am using this webservice on my asp.net page and I am calling this webservice asynchronously. So how should I increase webservice time out?
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:
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):
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.
In asp.net page, How can i call the javascript methods for form processing-submitting if the user browser supports javascript and use code behind events if the browser does not support javascript.I have the javascript code to send the form data to an ajax server page using jquery. Don't know how to invoke the needed one based on the browsers javascript availability
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript"> </script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
The jqGrid has been kicking my butt (as well as others on this site). I can't seem to get the JSON data from the webservice to load into the jqGrid when using the addJSONData method.
I am not using MVC just a plain WebProject webservice in ASP.NET 3.5.
I am using the latest version of jqGrid 3.5.
I don't know what to do. I am currently trying to load just 1 row that I am returning a string in my WS like this:
"Page:1,Total:1,Records:1,Rows:[name: Jeff V title: Programmer]"
Which is then passed into my javascript as:
{"d":"Page:1,Total:1,Records:1,Rows:[name: Jeff Vaccaro title: Programmer]"}
I am planning to use a Javascript call to a WebService to retrieve data from the database. At the moment I am using Ajax to do this. But since the Ajax is slowing down the performance of my application. I have read in some article that even though Ajax only refreshes the Update panel contents, Ajax does a full round trip to the server. What I need to know is how can I populate a Grid from data coming from a WebService via a Javascript call.
I'm doing a project in asp.net with a web services. My web services and my asp.net project is separate and my asp.net projet have a reference of my web services. i'm using visual studio 2008 framework 3.5 and my service web is in vb.net. i want to call the web methods of my web services in javascript my script manager is declared
service1 is the class of my Webservice and i call the function test with my button <input name="btnRecherche" class="btnRechercher" type="button" value="Rechercher un emplacement" onclick="test()" /> the problem is : JavaScript say Service1 is not defined but why .... What's the problem ? I've checked many forums and videos every body did it sorry for the french variable
After watching [URL] learning guide in accessing Web Service from JavaScript[/url] I was doing the same thing in order to test it. And found out that in my JavaScript I don't have any WebService in my IntelliSense. Such thing happens if I create WebService and WebSite either in one common solution or in the different.
I only want to execute this JavaScript function runEx() if publicVarFromCodeBehind != "abc".
I am setting the publicVarFromCodeBehind = "abc" in the Page_Load event but anyway the runEx() function is executing. I wonder how this works and how to prevent runEx() from executing though I need to catch the logic from C# and pass on the variable to the JavaScript.
I have a web form that has a button. The click event of the button submits the form for processing on the server. On the server, after the processing is complete, I want to call a JavaScript function. I don't want to attach it to a control. Just call it.
I want to send value from text on text keypress event in C# Code Behind Function. or get value from server side script function which called on textbox keypress event to C# Code Behind Function. How i do that
I'm using the CustomValidation Function to call my javascript but for some reason I'm not getting the * to indicate the error to the user. I keep getting a Function expected Error, so what is wrong with my javascript that's causing this error and why aren't I receiving the * notification?
Javascript:
<script type="text/javascript" language="javascript"> function checkAGITotal() { var a = document.getElementById('<%= NumberInHouseholdTxtbox.clientid %>').value; var b = document.getElementById('<%= AGITotalTxtbox.clientid %>').value; if (a == "1" && b <= "27247" || a == "2" && b <= "35630" || a == "3" && b <= "44014" || a == "4" && b <= "52397" || a == "5" && b <= "60781" || + a == "6" && b <= "69164" || a == "7" && b <= "70736" || a == "8" && b <= "74020" || a == "9" && b <= "81500" || a == "10" && b <= "88980" || + a == "11" && b <= "96460" || a == "12" && b <= "103940") return true; else return false; } </script> vb.net code: Total: $<asp:TextBox ID="AGITotalTxtbox" runat="server" Width="116px"></asp:TextBox> <asp:CustomValidator ID="AGITotalValidator" runat="server" ControlToValidate="AGITotalTxtbox" ErrorMessage="Your household income exceeds the maximum allowed." ClientValidationFunction="checkAGITotal()" SetFocusOnError="True">*</asp:CustomValidator>
