****TextBox.TextChanged Event
How to: Respond to Changes in a TextBox Web Server Control
Edit:
From your edit it would be better to use AJAX.
You can fetch data from oracle database from C# using the AJAX call and return the result to the response and display the data.
If you're using webforms you could use a WebMethod to invoke the query from javascript, you can see an example here.
You could also just add a control that invokes a function server side and use the FindControl method of the ListView to obtain the value of your textbox. Also if you want the function/method to be called when the user stops typing you could use a jQuery plugin called typewatch you can find it here. Also taking into account the WebMethod* attribute that I mentioned earlier in the answer.
Go through the article Complete ListView in ASP.NET 3.5. This article shows how to place textboxes inside listview and edit the data in listview.

i tried to dynamicaly load GridView on the existing page from server. However, when I get the html from the server and insert it into the element, grid appears, but some actions are not available on it (for example drag and drop on columns, filters and so on). Moreover, i have a callback on init event and controls init event, but they dont invoke. Recently, i have loaded gridview with full page and all was good. On support center i found that i need to use ASPx.Evt.DispatchEvent(window, "load"); after insert gridview in my page, but there isnt any explanation about this. Currently, after i have added this piece of code and most of functionality works well and client side events fired, but some are still broken, for example GridView.PerformCallback();. What else i need to do to init controls on my gridview?

The aforementioned ticket refers to the MVC Extensions product, not the WebForms.
In the meantime, why do you need to render the HTML and add it to the DOM and initialize manually? It is not a good practice for the server-side controls (i.e., when the client-side counterpart should be properly processed).
If you need to add the DevExpress ASP.NET WebForms control dynamically, consider using, for example, ASPxCallbackPanel.
I am using AngularJS to implement a DevExpress control on my website. This control is of type dx-data-grid.
The control works perfectly but I run into a problem. In the mesh I have a series of records that I want to modify. I know how to control when editing starts (using the onEditingStart function) but my problem is that I do not know how to control when editing ends, because at that point I want to send the list to the server to modify it.
The View:
enter image description here
The function that controls the beginning of the edition is:
onEditingStart: function (e) {
console.debug("EditingStart");
},
Thanks!
I suggest you to use rowUpdating or rowUpdated event as per your requirement. At these events you can create list of records to pass to custom server side code.
If you require any further information then provide more information about the current implementation.
Hope this help
Pretty basic question, I have a checkboxlist inside of a wizard control. I need to collect the value of all items that are checked, as well as whatever value is inside of a textbox if "other" is checked, to insert into my database during the Wizard.FinishButtonClick event. How do I do this? I need this in VB, please.
We cannot give you complete code to implement the task you want to implement, but can provide some starting point. Please go through the articles given below. Get back to us if you still have problems in implementing what you want after reading these.

In Ajax,is there any technique exist to validate ASP.NET GridView, i.e., to check whether the GridView contains at least one row?
Any comments welcomed.
I assume you render the GidView on the page. If I get you can check it using Javascript/jQuery on client side...
If you want to check it on the server side you have to call a method on the .aspx page using Ajax. In this case you should create a static web method on the page that check how many rows the gridview has got then you have to call that method using Ajax or jQuery

I have a standalone webform (no masterpage) that opens in a div from another page. The standalone page uses jquery to move a user through a non-linear questionnaire. At the end of the questionnaire there is a result displayed with a "complete" button. When the user hits the complete button the result is sent back to the parent/host page of the div.
I have a new requirement where i need to actually pass the question and answer id's to code-behind or web service where i can insert the question and answer id's to my DB.
None of what i need to do requires object serialization. I want to do this as simply as possible.. none of the controls in the questionnaire are server controls.. just regular select boxes or radio button groups. I suppose i could do an ajax postback using an update panel or something but not sure if making the controls runat=server will screw up all the jquery/js i have working in the questionnaire.
Any help is appreciated thanks!
I would tackle this by using jQuery to post the data to a web service, which is fairly trivial. There's are a couple of code examples for doing this with asp.net here:
jQuery: Ajax call to asp.net webservice fails, server return 500 error
and
Calling a webservice through jquery cross domain
To answer your other question, putting runat="server" will not have an affect of jQuery's ability to parse the elements in the DOM.
