KeyDown Event Does Not Fire For 'enter' In AutoCompleteBox

Aug 18, 2010

I am using a Silverlight usercontrol in my ASP.NET web app.
The user control has several autocomplete boxes and it seems that the enter key never fires the keydown event in any of them while it fires for other keys.

I'm assuming that autocomplete boxes must handle the enter key in a different way, perhaps for chosing an item from the list. - Thus it works with simple text boxes.

I was thinking about overriding the eventhandler in a new deriving control...

Aug 4, 2010

I have a textbox on my page and the second a user puts something in the Textbox i need to make a save button visible.

I thought I would do that with a keyup or keydown even. However, all I can find in my Text box is OnTextChanged. This only fires when enter is pressed. This is not want I want.

Is there anyway to fire a Keyup or keydown event when the user types something into the textbox?

AJAX :: Dropdownlist Selectedindex Changed Will Not Fire And Update Gridview In UpdatePanel?

Oct 6, 2010

I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.

Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)

I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.

It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.

AJAX :: UpdatePanel Conditional Update OnLoad Event / Updatepanel To Update On Queue?

Aug 25, 2010

i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.

all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.

but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

AJAX :: How To Fire A ModalPopupExtender On The SelectIndexChanged Event Of A Dropdownlist

Mar 17, 2010

How can I fire a ModalPopupExtender on the SelectIndexChanged event of a dropdownlist?

I only want it to fire when a particular value is chosen in the list.

I tried leaving the PopupControlID value out and calling .Show() on my extender in the onselectchanged event, but it would not allow me to have a blank PopupControlID. If I set the PopupControlID to the ID of my dropdownlist, the popup fires as soon as I click on the dropdownlist control.

AJAX :: SliderExtender Causes TextChanged Event To Fire On Every PostBack?

Oct 7, 2010

I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?

I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).

The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.

However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.

Is it possible to prevent postback unless the slider has actually been moved?!

AJAX :: Why Buttons OnClick Event Only Fire 2nd Time Round

Basically I am using a ModalPopUpExtender and it works fine, except that the OK button has an OnClick event that only fires when it is clicked for the 2nd time.. obviously i can progress with populating my OnClick event method for later on - its just annoying that a user has to click my button then ok in the pop up twice before they can get their intended result!
