Hi, Thanks but
i tried doing like
document.getElementById("<%=mylinkBtn.ClientID %>").enabled="enabled";
this didn't work. I mean my mylinkBtn control didn't get enabled.
is there any tutorial or something where i can check what are the properties like enabled, disabled,visble...etc

As the LinkButton control would be rendered as a tag at run-time and this tag does not have any attribute to enable or disable it, it would not be possible but if you use a HTML Button element or even a asp:button, both would be rendered as a tag and it would support the disabled attribute and so you can write your code like this:

<br />
<script language="javascript"><br />
function Showme()<br />
{<br />
var button = document.getElementById("myButton");<br />
button.disabled = false;//or true<br />
}<br />
</script><br />

See the "Remarks" section. If that doesn't answer your question, try to elaborate.

ASP.NET 2.0 - App_Code Folder

hi all,

my problem is in previous ASP.NET (VS 2003) writing a
function that grabs a string value from a textbox is as easy as:
dim str as string = me.TextBox1.Text

but with visual studio 2005 I can't do this simple way because the class for
that form is placed in the app_code folder and it will not see non of the
web controls on the web form, so saying:

dim str as string = me.TextBox1.Text will not work and it complains about
the TextBox1 is not defined. in more details, I have a function was working
in visual studio 2003 that calls a stored procedure in sql server 2005, this
function passes a variables (3 variables) from a 3 textboxes on the form.
And I am calling this function everytime the user changes the value of one
of these textboxes.

now since the migration, visual studio 2005 puts all classes under App_Code
folder (as one of their new features!!) moving my function under the
App_Code folder prevents me from calling/Getting the values of those
textboxes as they change why? because the class can't see those controls
sitting on the form!

I am going crazy with this. Does anyone know?

thanks for your help.

Just use the code behind page. When you add a web form make sure you check the 'Place code in separate file' checkbox then there should be a little plus sign next to the .aspx page, when you expand it you'll see a .aspx.cs (or .aspx.vb depending on language) file where you can do all you work with the controls. app_code is for more universal code like business logic (though I normally make another project in the solution for this), server controls, or help classes.

thanks eggsovereasy for your reply,

this is a very good news, because i was chatting with some guys and they told me that i HAVE to follow the new format (App_Code) and the old VS 2003 is being discontinued and it would increase performance or something like that. anything true to that?

plus, do u have any idea if a project has already been migrated and(all classes being moved to the App_Code folder), if there is a way to move all those classes back behinde their forms? or i have very much to re-migrate?

-- I just did a re-migration and there is no option or checkbox to force visual studio to use code behinde page! any idea?

thanks a lot

Hi,
I want to fill default white backround color inside the asp.net checkbox to some different color (e.g. gray) but none of the properties exposed by asp.net checkbox control seems me to do that. does anybody have any idea about how to achieve this.

Regards,
Amit

This makes it gray for me:

<asp:CheckBox id="cb1" runat="server"
BackColor="#CCCCCC"
Text="My Checkbox"
/>

Mike,
I was asking to fill the checkbox with gray color and not the outside area of the checkbox.

Urgent help required about Repeater Control

18-Jan-07 7:28

Oh. I see. I don't think you can do that, even with CSS. The solutions I have seen have resorted to using javascript to swap images between a "checked" state and "unchecked" state, using a colored box as for the images.

Hi all,

I have been working on a "web interface" project but I am unable to get it working. Here is what I want to implement. I have been trying to bind the 5 Listbox controls to a single Repeator Control. I have populated the 5 Listbox controls from the underlying database tables. Whenever the user selects values from each listbox controls the result should be displayed in the Repeater control. I can bind one listbox to the Repeater but I can't bind all five listboxes at the same time.

Looking forward to your reply

Thanks for your help,

Koonda

You can bind your repeater to an ObjectDataSource control, which is configured to use a method that takes 5 parameters. Then use ControlParameter controls within the ObjectDataSource, each configured to pull a value from one of the listboxes. Use AutoPostBack=true on each listbox so that a change in any will trigger a postback, refresh the ObjectDataSource, and redisplay data in your repeater.

That's one way to do it.

Thanks Mike Elison,

But I need some code examples. I am not using any code to get this project done. I am just draging the Listbox controls and a Single Repeater. I just change some html in the aspx file for the Repeater Control to get the values. Could you please send me some code to bind all the 5 Listbox Controls to the single Repeater Control to display information to the user

I realy appreciate your help.

Thanks

Nope. Databinding to a control like the Repeater is such a ubiquitous task - you need to understand it if you're going to get anywhere as an ASP.NET developer working with data. You need to look into the ASP.NET tutorials at:
http://www.asp.net/learn/default.aspx?tabid=63[^]

- the data tutorial particularly. And you'll want to look into MSDN documentation[^] on the topic.

I tell you what... look over all the material on those links. If you still have questions on displaying data in your Repeater (using values from 5 controls as parameters) post your question again.

Thank you very much for the links. In your 18th January reply I was confused with some terms, such as you said use the ControlParameter controls. What do you mean by that. Do you mean the ListBox control parameters or the Repeater control Parameters. Please also tell me is there any way to do that without coding?

Thanks
