I have a main.aspx page, it contains several tabcontainers. In each tab container, there is an iframe with the src="myPage.aspx".
In the myPage.aspx, I have added two comboboxes. The buttons of the comboboxes do now show at all until a postback on the myPage.aspx.
I have a situation where I need to have close to 30 drop down lists on one form. The user also wants the autocomplete functionality. I decided to use the ASP.NET AJAX control. So that the page will load faster I hide them until they are needed. But, as more and more become visible the postback time is getting longer and longer.
I know this can be fixed, but I'm not sure how. Can anyone give me any advice, point me to some articles? Do you have a suggestion for another method of doing what I need? Maybe, I shouldn't even be using ComboBoxes for this?
i have 4 comboxes (com1, com2, com3,com4) and 4 tables (tab1, tab2, tab3, tab4)com1 and tab 1 have master table relationships i.e when in com1 the name is entered tab 1 shows the result of that entry. the same is for the rest comboxes and tables.
Now what i am trying to do is when an user clickes on com1 and types the name of the employee tab2 tab 3 and tab 4 should be hidden. if com2 is clicked tab1 and tab3, ta4 shoud be hidden.etc
Currenty i am using this code which i do not like. Is there any easy and short way to do hide an show.
this is the code i am using
<script type="text/javascript">
$("#com1").on('click', function () {
$("#div1").fadeIn();

I have the latest toolkit build (3.5) and discovered that a ComboBox button width and height is being set to zero and not displaying correctly after switching tabs, posting back in UpdatePanel, and returning to original tab.
Steps to recreate:
1. Run code and start on tab 1
2. Select tab 2
3. Select a Product to postback
4. Return to tab 1 and notice combo button is gone

I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
in aspx i written as follows
<ajaxToolkit:ComboBox ID="cmbAddressAlias" runat="server" DropDownStyle="Simple" AutoCompleteMode="Suggest" CaseSensitive="false" AutoPostBack="true" RenderMode="Inline" Width="170px" CssClass="cmbProvince" OnSelectedIndexChanged="cmbAddressAlias_SelectedIndexChanged"> </ajaxToolkit:ComboBox>
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
I'm posting this here because is related with ajax:
I need to upload files without the postback. So far i know that i can use an UpdatePanel with an AsyncFileUpload to achieve this, and it works fine, but this is not enough for me. Turns out that i need the fileupload control to be invisible until the user press a button. then i have to show the file upload control also without the postback, that's why i'm using the updatepanel. To acomplish this i'm using the following code:
[Code]....
if i don't use the normal panel it works fine, but when i put that control, it doesn't work. By "doesn't work" what i whant to say is that it doesn't fire the OnUploadedComplete method.
I have a modalpopupextender and I want to be able to update the information without causing a postback and having to re-show the modal, normally I use an updatepanel and this is working in most cases but I have an issue with a repeater where the ItemCommand has been set but clicking the button does not fire anything, unless I set the repeater as a trigger but this then does postback and I lose where I am. Not the usability I want to provide.

So how I can get the value of the file once the button click?
I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
I am using asp.net 4 and I am writing this function to disable postback button
<script type="text/javascript">
var pbControl = null;
var prm = Sys.WebForms.PageRequestManager.getInstance();[code]...
however , It's working on asp.net control but It's not working on controls that are input with runat="Server" , it's giving error object expected
I have 2 link button in my page and every thing was working fine until i added window.onload() method on my page.
After adding window.onload() first link button is working but not the second button. I am using update panel in my page
want to do a page refresh when a button inside an update panel is clicked. Is it possible and how?
View 7 RepliesI've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
Any code related to modal popup to stablise is necessary and if the values are enter correctly then modal popup should get post back.

Why do I have to press the "Enable" button twice to enable a disabled ComboBox ?
I have an update panel which is inside a Modal Popup Extender. When I click the Refresh Report button it always calls a postback. I need to stop it from posting back.
View 2 RepliesI have a link button inside a template field of a gridview. The gridview is wrapped in an update panel. I want the link button to fire an async postback but it always fires a full postback. Why is this?
This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.

I have a textbox with an autocomplete extender.The user types in a few chars and usually gets a few to a few hundred suggestions back.And its pretty quick.This is on a formview control at the bottom by the paging. It is for a "Go to" feature.But it is returning the suggestions from the same list of search results from the previous page.(It's really the same page but I just toggle the visibility between the GridView Results and the FormView details).And if they select "All Tickets" its possible to get 5000 results from the search.
Now the autocomplete is really doing the same search as the search results did which is like 46 seconds. And then weeding it down further with the prefix (chars they type in the autocomplete textbox).I have a Return to list button. And I want the Button to interrupt, stop, cancel, abort, or somehow just not wait for the WebMethod to finish, and do a PostBack right away.Since btnReturnToList is a normal postback I can't really use PageRequestManager to check if in async or last postbackelementId or anything.
i am tryin to show the image on the button click. the .cs file contains the database connections so when at the click of btn1 as the database searches i wanted it to display the image below. if i am goin wrong anywhere.and the file below is a .ascx file.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<br />
<asp:Button ID="btn1" runat="server" OnClick="btn1_Click" Text="OK" style="width:155px; text-align:acenter;" colspan="1" Cssclass="buttonNormal" />
<asp:UpdateProgress ID="UpdateProgress1" runat="server"

<ProgressTemplate>
<img border="0" src="~/Images/ajax-loader_2.gif" alt="" style="left:450px; top:250px"/>
</ProgressTemplate>
</asp:UpdateProgress>
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="btn1" />
</Triggers>
</asp:UpdatePanel>
it is supposed to show me that image when i click on btn1. the above code runs but with no results and also it places this line of code when the app is built
"<System.Web.UI.PostBackTrigger ControlID="btnAuswhal"></System.Web.UI.PostBackTrigger>"
function showPopupClick() {
$find("my_ace1").showPopup();
}
Although I can debugger-watch the ace returned by $find. If I call showPopup() it only returns undefined.
I have below code to show processing when button clicked in the updatepanel. But it does not disable the page and processing icon is not showing in the centre. How to disable the page and put the processing icon in the centre when button is clicked according to below code?
