Web Forms :: Filtering A Textbox As The User Is Providing Input - Using Ajax "FilteredTextboxExtender"?

Jan 31, 2011

I need to filter user input into a textbox - as the user inputs the text (as opposed to examining the textbox on the textchanged event) The FilteredTextboxExtender does the trick, but there is a catch. I want to add formatting (currency) AFTER all of the input is collected in the textbox. The "FilteredTextboxExtender " prevents this from happening. This extender does have a property "Filtermode" which can be set to either "ValidChars" or "InvalidChars" at design time, but I do not know if it can be set at runtime.

Any solutions would be most appreciated. I am also open to other solutions to the problem - which is : do not allow chars other than numeric into the textbox, until the textbox has lost focus, at which time, currency formatting is to be applied.

AJAX :: Update FilteredTextBoxExtender From AsyncPostbackTrigger?

May 28, 2010

I have an ASP.NET Label on my form, which is wrapped in an UpdatePanel. The UpdatePanel has two AsyncPostbackTriggers which reference two DropDownList controls. Based on the combination of selected items in both DropDownLists, I'm updating the Label. I also have a FilteredTextBoxExtender referencing an ASP.NET TextBox that's, by default, only allowing numbers. Now, along with updating the Label based on the combination of selected items from both DropDownLists, I'm also changing the FilteredTextBoxExtender's FilterType to Custom | Numbers and ValidChar to a hyphen, to allow both numbers and a hyphen (for phone numbers). Remember that I have both DropDownLists as AsyncPostbackTriggers for the UpdatePanel. This works perfectly fine doing a regular postback, but if I add those two DropDownLists as AsyncPostbackTriggers, the FilteredTextBoxExtender is not working properly based on the FilterType and ValidChar properties. It only allows just Numbers, which is the default. Is there anyway around this without having to do a regular full postback?

AJAX :: Unable To Close/hide Ajax:popupExtender, When Used Inside A Gridview/Itemtemplate

Dec 15, 2010

I am fairly new to web development & stuck up using the ajax:popupExtender inside a gridview/Itemtemplate. So, would like to get help from experts in the forum


Currently I m developing a web page which holds a grivview. As one of the column needs a multiple column dropdown with soring facility, I am using ajax:popupExtender to achive that. Basically in the column i have a Panel1(label & image which mocks up has a dropdown), ajax:popupExtender, Panel1(gridview to have mutiple column). When user clicks on it the ajax:popupExtender is called & the targetpopupid which is a panel2 with gridview is called.

Here when user clicks on thePanel1, I am able to display Panel2 using ajax:popupExtender. Also, when user selects some row, I am able to close/hide the ajax:popupExtender in the code behind using cancel(). (this is done in selectItemIndexchange of panel2 grid view).

But my problem comes when user doesn't select any row & clicks back on the panel1, the ajax:popupExtender will remain open. but it should have been closed as i am trying to mock up dropdown dunctionality. how can I hide/close ajax:popupExtender when user clicks on panel1 2nd time.

Following are the different approaches I tried but nothing worked out.

1. wrote JS, & tried to add attributes of the Panel1's onclick event.
Failed: Error - Object is undefined. even though i passed a valid obj from code behind.

<script language="javascript">

AJAX :: TextBox AutoPostBack Inside UpdatePanel?

Jul 29, 2010

I have two textboxes insie an updatepanel, the same update panel also has a trigger from a Clear Button from the other update panel. The first Textbox AutoPostBack is set to true. The first time when the textchanged event is fired, everything work as expected--the labels got populated, the focus is set to the second textbox. However after I click on the Clear button, i entered something to the first Textbox, its TextChangedEvent fires--the labels got populate, the focus seems set correctly to the 2nd textbox, but I
cannot enter anything to the second TextBox. it seems like the form is not active--when i hit tab, I expect the focus move to next control, instead it moves to the URL box. Turn off the AutoPostback then put a button next to the first textbox will fix the problem, but I am wondering if there is other workaround to keep the AutoPostback of the 1st textbox?

I am using IE8, here is a simple test page:
