AJAX :: Using Textbox Onchange To Trigger Updatepanel / Gridview?

May 25, 2010

How can I get a gridview (that is inside an update panel) to update/filter whenever something it typed into a related textbox outside that panel..( possibly in another update panel)?

As in Google. When you start typing, it starts autocompleting for you by looking up words in the background using the text you've typed.

I want, in effect, for a user to start typing in a textbox (say "Order #" textbox) and each time a character is typed, to trigger an update to a gridview that has a 'search param' in it's SQL Datasource SP that plugs the textbox's text into the where clause of the select inside the SP...

make sense? I have the SP and all other related code, I would just need to know how to create a JS function (preferably via server-side using something like:

txtOrderID.Attributes.Add("ontextchanged",....

Rather than hardcoding client-side JS....

AJAX :: Unable To Maintain Focus On Dynamically Created Textbox

Jun 30, 2010

i have a WSS 3.0 Webpart that contains an UpdatePanel with a customized SPGridView. I want to provide instant filtering of data by adding a textbox below the column header when the column shall be filterable. There is a jQuery based solution for this on the net, but it's totally client side and doesn't work with paging, so i tried it on my own.

In the CreateChildControls of my SPGridViewExt class i have :

[Code]....

I've also overridden the DoFilterPostBackEventProcessing method to create a "[ColumnName] LIKE '%[textbox.value]%'" filterExpression for my datasource which also creates the LIKEFILTER_COLUMN and LIKEFILTER_VALUE ViewState Items so i can identify the textbox that should refocus on after the postback. The filtering itself works great, but whatever i try, i am not able to set the focus to the textbox after entering the first letter.

[Code]....

All these four methods don't work. The registerstartupscript call doesn't even render the script when i search the page source after postback. I also tried to add a HiddenField to my webpart and set it's value to the control id of the textbox in onfocus, then register a startupscript in OnLoad that focuses the control if the HiddenField has a value, but to no avail.
