I have a web forms page with a button that involkes a __doPostBack callback to the page. I would like to invoke this manually - by "manually" I mean from outside the webpage, for example by using wget.

i am doing this in my client side to make my page load and update a message that is inside and update panel, i associate the keydown event of a textbox control to this javascript:
[Code]....
but the problem with that is if the user type fast the page will do a lot of postback, and i just wanna make the last one, how can i afford that??
Clicking the link does perform the postback, as verified by a breakpoint in the code-behind. Also pasting javascript:__doPostBack('ctl00$c1$btnRefreshGrid','') in the address bar of the browser works with the same effect.
I want to call javascript function on label onload, reason I am using an enitity Datasource and assignng a value to this label, but I want to hide it if the value is empty.
I created a simple Master Page in Visual Studio 2008:
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
and got green underlined 'Master' with two warning messages: 1.Validation (ASP.NET): This attribute name must be followed byan equal (=) sign and a value. If the value is in quotation marks, the quotation marks must match. 2. Validation (ASP.NET): Attribute 'Master' is not a valid attribute of element 'Control'.How I can get rid of the messages?
But when i deploy the project on the production server, it does not raise the event although i have checked that the function getting called but the event is not raised.
In short
* javascript:__doPostBack('<%=lnkSaveBtn.UniqueID %>',''); in javscript works using http://localhost:2000/myProjectName/Home.aspx
*javascript:__doPostBack('<%=lnkSaveBtn.UniqueID %>','');not works when using http://machinename/myProjectName/Home.aspx
I have tried using javascript:__doPostBack('<%=lnkSaveBtn.ClientID%>',''); but still does n't work.
i have explicitly added __doPostBack() on Button onclientClick event .
[Code]....
When I am clicking the button the Page_Load is calling twice.
But if I am adding below code inside page load ,page load is calling only once on button click.
[Code]....
and return true is giving me again twice page load ,but adding return true or false in attribute.add code is giving the same result ,only one page load call.
[Code]....
I am not able to understand what is going on exactly I try to add __doPostBack in different way.
I am calling a method with __doPostBack using the OnFocus event for the controls. However I need to update the values multiple controls when the server method executes. This actually causes on focus to keep firing. Looking for help. I tried using TextBox1.Attributes.Remove("onfocus") and then adding it the javascript after processing but it still keep looping. Here is a sample using to textbox's for simplicity:
I have a login.ascx control with three controls (LoginName, Password and btnLogin) , I want to rase a click event on this button from .aspx page because some restriction is there so that I am unable to write any code on .ascx page.I am bale to put loginName and password on .ascx by using query string but unale to raise event.
Im getting that error when try to call a __doPostBack on one of my pages, every page that i have in the project use __doPostBack function but in this particular page im getting that Javascript error.i was looking in the internet and the only thing i read is that this error happends when i have a unclose tag but i review the site and its ok.Error: __doPostBack is not definedSource File: htt://localhost:99/ProjectName/Disable.aspx
I'm sending a value (id) from javascript like this:
__doPostBack('',id)
and at the server side I get it like this:
var id = Request["__EVENTARGUMENT"];
the problem is that sometimes other controls also do stuff and the var id also get's value but not with the value I sent, but some control did.how do I send this value separately so that in var id only the value that I sent using js can be.
I'm having a problem with telerik RadGrid, I want to enable multiple row selection. I also want to go to the server whenever a row is selected or deselected. I created a javascript function to handle the Grid's client side events (OnRowSelected, and OnRowDeSelected). The functions look like this:
function onOperationRowSelected(sender, eventArgs) { __doPostBack("<%=myControl.ClientID %>", "rowSelected:" + eventArgs.get_itemIndexHierarchical()); }
The other function is very similar, the only difference is that it sends the string "rowDeselcted" instead of "rowSelected".
On Page_Load I check to see if the request is a Post request using "IsPostBack" and if so, I check to see if it's a rowSelected or rowdeselected.
My problem is when I select a first raw on my grid, a Post request happens (which is expected), however, when I select the second row, a GET request is issued, which (obviously) will result in IsPostBack returning false.
