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??
I have a LinkButton that I need to perform a click on to cause a postback. The actual link target is:
javascript:__doPostBack('ctl00$c1$btnRefreshGrid','');
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've tried the following with no effect at all:
__doPostBack('ctl00$c1$btnRefreshGrid','');
$('#ctl00$c1$btnRefreshGrid').click();
$('#ctl00$c1$btnRefreshGrid').trigger('click');
eval($('#ctl00$c1$btnRefreshGrid').attr("href"));
I've tried using both <%= btnRefreshGrid.UniqueID %> and <%= btnRefreshGrid.ClientID %> to generate the selector.
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 am raising an event from the javascript function using the below code.
javascript:__doPostBack('<%=lnkSaveBtn.UniqueID %>','');
The event fires when using the below URL
http://localhost:2000/myProjectName/Home.aspx
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 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 tag:
<asp:ListItem
CssClass="LabelCSS">Executive</asp:ListItem>
and I am getting the error message
Validation(ASP .Net):Attribute CssClass is not a valid attribute of element ListItem.
What attribute would I use for Css with ListItem?
why the ValidateRequest dose not work when html tags had sent by __doPostBack method in javascript.

I have abit of a problem, with the AutoEventWireup setting.
Currently, my master page's onload seems to fire twice. If i set wireup to false, it doesn't fire at all.
All my page, using the masterpage, also has the setting set to true.
Should i only have it set to true in the master?
What happens to my events in the indidual pages then? Does the masterpage handle the wireup, if they are set to false, and it is set to true?

I'm trying to create an asyncrhonous postback in asp.net using __doPostBack(), but I have no idea how to do it. I want to use vanilla javascript.
Something simple like a button click can cause the __doPostBack() event to fire. I'm just trying to learn how the mechanism works.

View 4 RepliesI'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 put following on Page_onload event, I am not sure why it is not working. However when I use with dropdown, it is working fine.

I am trying to dynamically add buttons to a gridview during the onload event.
protected override void OnLoad(EventArgs e)

I want to call a javascript function at onload event of gridview..But I am getting Compilation error. How can I do this?
Basically I am using a javascript in .aspx page which have a master page. I want to get the value from javascript in code behind.
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.
What am I missing here?
