thanks for the response,

but how can I declare the onChange event for the boundfield/textbox that shows up in the grid?
I mean, where should I do it?
I create the grid column at runtime, is there any way to set the onChange of the boundfield at this momment?

thanks

Yes, use GridView's RowCreated event. eg.

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
    TextBox tb = (TextBox)e.Row.FindControl("Textbox1");
    tb.Attributes.Add("onchange", "onchangeFunction();");
}

and is it guaranteed that the textboxes have names like textbox1, textbox2 and so on? I mean, gridview created this controls by itself, I don't name them...

thanks

I never tried that, you can check the name by placing a breakpoing in that event and search for the controls gridview created. or name will be same as you write in columns template.

Why do you show us the 'register' part ? Is the event inside the control's .cs file ?

You mean Usercontrol .cs file..Yeah i wrote my method in usercontrol..i am calling stored procedure in usercontrol to display list of years..

Christian Graus17-Jun-09 13:28

17-Jun-09 13:28

I notice you use Object instead of object, but I'm not sure that should matter. Other than that, I see no reason, if the control is in usercontrol.aspx and the event is in usercontrol.aspx.cs, for there to be an issue.

Have you copy and pasted the code snippets and the error message? I ask because the method name in the error message doesn't match those in the code.

Hello, Not sure if this is the correct place to ask this question but I'll give it a shot...

I have a need that perhaps one of you can point me in the right direction with...

I would like to implement something very similar to what’s out on www.target.com or www.gap.com.

When you click a button (quick view, quick info, etc..) you get a new window with product pics and info.

Here's the link:
http://www.target.com/Star-Wars-Clone-Favorite-Characters/b/ref=nav_t_spc_10_23/184-2346213-9435346?ie=UTF8&node=673254011...(and click on "Quick Info" under any image)

Perhaps I can do this with a widget or something else but I’m not sure what kind of widget it would be. I believe it's done with Ajax!

If someone could provide "ANY" useful information, it would be “GREATLY” appreciated Smile | :)

Thank you in advance,

~Mario

Re: ??Ajax Pop-up Window??

17-Jun-09 11:28

I would suggest that you need to do some reading. I don't believe you have any idea what AJAX is or does. This COULD be done with AJAX, but as it's just a popup window, that appears wasteful to me. However, the ASP.NET AJAX library probably does have a control for this sort of thing, it seems like it's a styled div, which would mean it's sitting on top of a transparent div, to stop interaction with the stuff underneath. You could use AJAX to request the script, or you could push the script down with the page, ultimately, this is done with javascript. You can probably right click on the page and view source, and probably open some include files, to find the script that does it, but it sounds like you should focus on some more basic stuff, first.

~I don't believe you have any idea what AJAX is or does.~

That is why I was asking, duh!! Anyway, I figured out on how to do it is by using a ModalPopup window. Thanks for the info and vote of confidence...

Well, I guess my point is, if you use things you don't understand, then you're going to run into issues.

Yeah, that makes sense. The point tho, is that if you use stuff you don't understand, you will get in trouble.

the user must first enter a value then click enter...This redirects the user to an internal search engine page written in javascript. i want the value to display in the internal search engine text box. I can get it to redirect but I get the error 'txtSearch2 is not part of _Default Class' in the code behind.
Me.txtSearch2.Text = Request.QueryString("Name")

if you need more info please let me know!!!!!

um.... no. The answer is no. you need a runat="server" for this to be aserver control. Why not just use an ASP.NET textbox ?

I get an error when I create the <asp:textbox> control. it says search() is not a recognized member the .aspx page....The search engine is a Javascript search engine with the search() implemented in the javascript. Once the user hits the search button I wanted this to trigger the search engine preferably with the <asp:text> but the only way I can get it to work is with in the input text....This is a copy of my javascript search():

title = new Object();
desc = new Object();
links= new Object();
matched= new Object();
keywords= new Object();
found= new Object();
var temp=0;

// keywords as parsed from the input
// # of titles present in the database
title[0]=45
//no of keywords after parsing
keywords[0]=0
//no of matches found.
found[0]=0

this is the html input boxes

<form name="searchengine" onSubmit="search()">

Keywords:

How can I implement the <asp:text> and still get the same results.....
Thanks for your time!!!!

Hi, what I need to do is to hide the links for some images and files in my website from the public, so they can't direct link to these images.

Can someone help me out eith this?

You can't hide links. You can write code which checks the referrer on a link, a http handler which all links to images pass through, and which reject them if the referring page is not your site. Request.UrlReferrer is the property you need to look into.
