I've an UpdatePanel where according to operations inside of this UP is filled. I've add some buttons but the buttons to not fire clicks. I've used the code

im using an update panel and my web form consists of textboxs and combo box, my problem is that when i click the button save for the first time, my page simply postbacks and the event save wouldnt fire, click it the second time and poof save will execute.. I notice that it is caused by my dropdown box and textbox autopostback function, i need to set this to true since i need to execute another function that will disable the dropdown when the textbox is filled and vice versa,set this to false and save will function normally..any ideas how to fix this?
here is the code for that.
<asp:DropDownList
ID="ddNewLocation"
runat="server"
Width="95%"
AutoPostBack="true"
AppendDataBoundItems="True"
onselectedindexchanged="ddNewLocation_SelectedIndexChanged">
<asp:TextBox
ID="txtNewLocation"
runat="server"
Width="90%"
AutoPostBack="true"
ontextchanged="txtNewLocation_TextChanged"></asp:TextBox>
In my default Page I register this listener:
[Code]....
and this Event is never fired

View 2 RepliesI have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?
View 1 Repliesto explain my problem as simple as i can i have made the following page each textbox is a required field. when i enter valid data in the text box and click the button everything is fine. the problem i am having is that after this button click > i empty out the last 2 textboxes > click the button > the required field validation is not thrown.
the autopostback property being set to true is a must in this case.

So I followed Scot Mitchell's tutorial from asp.net/learn on adding a checkbox column to be able to select multiple entries and delete them with the click of a button. When I make my selection and click the button it works on the database end, as the desired entries are deleted. However, the entries remain on the page after it reloads. if I refresh the page it's updated properly but I'd like it to automatically update after the button is clicked.
Also, I tried his method for adding check/uncheck all buttons to the top of the gridview and they don't seem to be working either.
Here's the code behinf from the gridview page:

I have a very simple ModalPopup (with checkboxlist) + LinkButton in a page. I did everything as per the video tutorial. However, it appears that the first click on my linkbutton triggers a reload of the page and only after that, it starts working. How can I have it working the first time ?
Here's my code :

I'm developing a page which has a master page, and in the contentplaceholder I have an UpdatePanel with a GridView inside. Out of the UpdatePanel I have a button which calls to a ModalPopup, in the modalpopup i have two textboxes, an accept button and a cancel button. If I put the textboxes in a div in the contentplaceholder everything works fine, it recognizes the click button, it makes the insert into the gridview, and refreshes the updatepanel and the gridview But, if I try to make the same proccess from a ModalPopup the click event is not fired. I tried everything, and I didn't forget to put the triggers in the updatePanel to make asynchronoys calls to the server. How can I fire a click event from a modalpopup in order to make an insert?
View 2 RepliesI am working on a financial portal and I am having a problem..I don;t know what to call it so i mentioned it as an 'unknown to me' problem..I have a webpage..whenever I click on any button on my webpage, the request goes through..but nothing show up on the webpage..then If I click on another link and then again come back to previous link,then only I see the results of button_click..
e.g.
I have a currency conversion and investment form..so after filling up the form in following way and if I click on "INVEST" then nothing shows up..
so now if i click on any other link and go back to 'buy currency' link I see the result as 'investment successful'
I have a button like this:
<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />
If I write my client function like the following, it works as expected:
function ConfirmSave()
{
return confirm('Confirm?');
}
But I should check, inside the function, for the confirm result, like this:
function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}
Doing this, the page postback but the server click event doesn't fire.

I have a modalpopup that i have opening on a radiobutton selection. That works great, opens when it should and closes when you click cancel. BUT i have the following on my cancel button event that is not firing
[Code]....
I also have a button event for my "OK" button and that works great, but my cancel event doesnt seem to fire or work. Maybe the ClearSelection() is not what i need..
I want to clear the radiobutton if they cancel out of the ModalPopUp so they can make a new selection, since its a required field.
Before I go the route of using hidden fields or something similar, is there any way to send back to the server changes to the disabled state of an ASP.net Button control? I have a Button that is initially enabled and I disable it via jQuery on the client. Works great. The only problem is when I do a PostBack the server still thinks the Button is enabled and sends back a response that changes it back to enabled. Why doesn't the ViewState send back the current disabled status of the Button? Is there a way to force it to postback the changes? Other ASP.net controls, like the CheckBox, do send back the state changes to the server. Seems odd to me.
