AJAX :: Image Upload And Validation In Modalpopupextender?
Dec 13, 2010
The issue is that i am adding a new record and a image using modalpopup. Its working quite fine. I have to let my modal popup extender make a postback on insert button click because i have a image upload control in my modal popup.
It is working quite fine but the problem is that i have also used validation controls in my popupextender and when i click on insert button it checks the validations and shows me appropriate message but it do postback after showing message which it should not do at all.
i have master page which contains abutton to insert new message this new message should appear in Modal PopUp Extender Control which contains the 2 text Fields (title and subject] and 2 required files validatior controls also there is validation summary control my issue is when open the modal window the symmar validator control save its values and duplicates the error messages
I would really appreciate if someone can find out what's wrong with this code.
Here is my question. I have textboxes in a modal popup extender (City, state, zip) and there is an image button search for searching the address from the database. All this functionality is within a control (.ascx file). This control is added to the page where it needs to be displayed and is being displayed when a user click the Address button (the code for it is not shown here). The method ShowAddressSearch() in the control is being called from the page and it displays the popup.
When the user enters any of the 3 values and hits search a server event is fired up and the result should be displayed in a grid. What is happening is, when the user hits the search button the server call is made and the data fetched from the db but the modal popup closes itself here is the code for this. I would really appreciate if someone can find out where and how popup is getting closed.
I have a ModalPopupExtender control inside accordin control, users can add images, that I sotre the path in database(sql server) and the actual image in physical address inside web server,I automatically resize the image to thumbnail size in C#, when users first connect to the site,the see the thubmnail version of the image,which is much faster to download,and by clicking the thubnail, the hidden asp:pnael is shown with imzge in full size, I use javascript to unhide the panel and also change the image source to actual image,everything works fine in IE, but in Firefox and Chrome, the first time user clicks on thumbnail can not see the full size image,only after couple of time, they see the full size image? what could be the problem?
I am using asp.net ,C# what is the best way to achieve this?
I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
