AJAX :: Use A File Upload Inside An Update Panel Along With A Dropdownlist?
Jan 27, 2010
i m using an update panel on a page which contains a listview. the listview (in each row) has a fileupload control and a dropdownlist.
although both controls do not have any interrelated values, its a desgin constraint to use both of them inside a listview row (and hence ...n number of such rows)
everytime i change the selection in the dropdownlist, the file upload control clears.
i have been through this pos, which suggests putting the controls (which cause postback) inside an updatepanel (use AJAX) and keep the fileupload outside of ajax.
[URL]
however my problem is that both my controls are in ajax bound code (that is inside the update panel) and hence the selection clears the file in the fileupload control.
I am having dropdownlist and button in the update panel when i selected item from the dropdown list and click on the button the the item goes into the database
but only first value of dropdownlist is going into database when i selects other values and click on the button it is still inserting the first value of the dropdownlist
I've been wrecking my brain on how to solve this but I'm all out of idea. I have a FileUpload control within an UpdatePanel. I have a button, let's call this btnSave, that saves the FileUpload.PostedFile into an sql server. What happens is that when the btnSave is clicked, I would save the file to a ViewState as well as upload it to the sql server. I also have an ImageButton, call this btnDel, that clears up the ViewState that holds the File in the viewState. This btnDel is an Asynchrounouspostback trigger to the UpdatePanel that holds the FileUpload control. If I browse a file, click on btnSave, everything would work fine. However, if I browse a file, click save, click on btnDel, browse anotherfile using FileUpload, and click save, sometimes FileUpload.PostedFile has a file and sometimes it is null. I'm really not sure what's causing this. I know that there is an issue of incompatibility if btnSave is made to be an asynchronouspostback trigger to the updatePanel. I don't see how making btnDel an asynchronouspostback trigger could affect this.
If I do take out the FileUpload control from the UpdatePanel and remove btnDel as a trigger, everything works fine except a postback is generated, which the client does not like.
I have 3 upload controls ,one listbox and two button controls in page. One button control named Attach has the code to add the files to listbox form 3rd file upload control and the 2nd button control named Save has the code to save the files of 1st and 2nd file upload controls in application folder and items of listbox to database.
The issue is couldn't maintain the state of 1st and 2nd file upload controls after browsing the files to file upload controls and clicking on Attach button control to add file name to listbox which was browsed by 3rd file upload control.So i placed the 3rd file upload control, Attach button and listbox in update panel but its not working. My requirement is when clicked on save button files of 1st and 2nd file upload controls in application folder and items of listbox to database, but 1st and 2nd file upload controls will loose the files as soon as Attach button is clicked to add filename of 3rd fileupload control to listbox.
I have a detailsView inside the update panel., and in the detailsView I have a FileUpload Control and a button btn_Upload. In the click event I have written code :
when i m going to store img in db and using fileupload control it's not possible to store , but if i remove update panel and scr... manager i can. need soluation. i m storing img as image in db as filebyte
i have a website with an UpdatePanel and inside of it, is a button and a gridview, onthe click event of the button, if has the following codes:
[Code]....
Basically it exports the gridview data to excel, but it shows an error. it said that the error occurs when the website uses the "Response" inside the Updatepanel.is there an alternative to "Response" method.
I am trying to implement validations for a jQuery pop-up which is placed inside an update panel. I am facing problems using validation controls and I presume its because oft he ClientScriptManager it uses. I read in the FAQ section [URL] that we need to download and apply a hotfix to solve this.
Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.
I have a check box, RequiredFieldValidator and textbox that have editmask extender I want to change the control properties programmatically when I check the check box but the problem that nothing happened when I check it.
I made the control post back and I added triggers.
when put break point and go with code step by step will go through the code but nothing change.
i have an issue running JavaScript inside an updatepanel,
i'm using a script as follows:
[Code]....
and each time the update panel updates i load a new variables for the FlashFileName to display a different movie.
outside an update panel this works, but inside the script doesn't run, i have read on other posts that there is an issue with running javascript inside an updatepanel.
This is updatepanel code. as shown in the code, i am referring to ddlClass in triggers which already calls a javascript function loadAllDefaults();
The problem is, since ddlClass is calling javascript function 'onchange' property, i cannot call any other function of backend code and I want to refresh the updatepanel on the basis of selected value of dropdownlist.
How can i do this? I have created a function in c# code in backend but I am not able to call both functions together!
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.
2- i have Ajax Control ToolKit HTML Editor OutSide My UpdatePanel and its not inside any control.
my problem when make HTMLedior (visible=false ) onpage event, MyupdatePanel Render Control Much Fast, but when i Make it visible its slow my application althougth this htmleditor not included in any update panel and its not refreshed.
I have a page with three update areas, Create, Edit, and Delete. The controls that do these three functions are inside separate update panels so when I'm doing Create, I only fill controls inside that updatepanel. Problem is I'm using asp validation controls on all the controls in the three areas. Therefore, when I press the "Go" button in the Create UpdatePanel, the validation fails on the empty controls in the other two area. I hope I'm explaining this well. The behavior I would like to see is that only the controls contained in the updating panel would be validate.
have a wizard control inside an update panel. have a radiobuttonlist that autopostback's when i click a radio button, page posts back & the page hops back up to the top. i want a user to be able to click radio controls & checkboxes with the form to be fluent; the hop back up to the top is rather annoying & may confuse the user.
