AJAX :: Disable Button Before Portback Inside Update Panel?

Apr 2, 2010

I have an application that allows users to insert data into a log. The forms are displayed inside update panels and display via modalPopUpExtenders. I am running into a problem where users are able to click the Insert button multiple times before the panel can update that a click was registered.

How can I disable the Insert button once the user clicked on it and had time to communicate with the server? The system is allowing duplicate and triplicates to be inserted into the system.

AJAX :: Repeater Button Works Inside The Conditional Update Panel?

Nov 17, 2010

I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.

My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.

So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?

Web Forms :: AJAX Modal Popup Is Closing When Button Is Fired Inside Update Panel

Jun 26, 2012

 I am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section

1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient

bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User

will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also

2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station details 

On particular client selcted above.

I have given the delete station command on deleting the station that particular entry doesnot goes away. 

It Should not be visible after it get deleted

Now when i click on imagebutton a modalpopup will open. 

Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button

Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?

Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.

But when I am clicking on imagebutton it is closing the modalpoup.

And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.

<%--   ************** CLIENT SECTION START HERE*******************--%>
<p class="heading">CLIENTS</p>
<br />
<asp:ScriptManager ID="smClientMgmt" runat="server" />
<asp:UpdatePanel ID="upCMClientInfo" ChildrenAsTriggers = "true" UpdateMode="Conditional" runat ="server" >

AJAX :: Download File From Database Within A Update Panel?

Mar 3, 2011

I have struggled with this for the last 2-3 days. I have a tab container control with a update panel surrounding it. On one of the tabs I have allowed the user to upload and download files to a SQL Server database. The upload works fine and the download works fine only when I remove the update panel.

I have tried to implement the solution that's provided at the following location...http://encosia.com/2007/02/23/ajax-file-downloads-and-iframes/I had to modify the code a little bit to fit my scenario but it looks like it would work. Is there another way to download files from a database within a update panel?

If there isn't another way to do this what could be wrong with my code...following the example on the encosia site...

Page starting from [Code]....

The code never gets past the if statement with in this java script. Should I put a trigger on the update panel to force a post back. Any help will be appreciated, java script is not my strong point.

Conditionally Trigger A Full Page Postback From A Link Button Inside Update Panel

Nov 29, 2010

How do I conditionally trigger a full page postback from a link button inside of an update panel?

I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.

Here is the control hierarchy:

Custom Control

Event handler Pseudo code:

LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
End If
End Handler

Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
