Well, I believe that the only way to know about
these questions is practically working on them.
The more you will work and use the technology,
the more you will be able to understand and answer them.

This comes through experience and lot more reading.I would suggest you read a lot more case studies,you can get a lot on internet.You should know pros and cons of every concept,which suites where,Dos and Donts etc.So the basic funda, is read more,dig deep into very concept look for realtime examples.. it may take bit time but once you'll reach you will be giving your own solutions to the problems.
Cheers!!

Hi all,
I am trying to read the dropdown selected value in Page_Init Event, but i couldn't.
I have to dynamically add controls to form based on dropdown selected value.
please suggest me how to read dropdown selected value in Page_Init.
thanks in advance.

In normal scenario, you cannot read the any
entered value from client side in your Page_Init event.
(If you wish, you can read the posted form manually and
get to know about the dropdown selected value)
In Asp.Net, your control gets populated with value after Page_Init
event and before Page_Load event.
So, your values will be available at Page_Load and later events.
I will suggest, things would be easier if you push the logic to
Page_Load event or later.

I would consider using JQuery, http://jquery.com/[^]

document.GetElementById('ctl00_MainPlaceHolder1_TextBox1')
should be
document.getElementById('ctl00_MainPlaceHolder1_TextBox1')
The getElementById starts with small letter.
This might be your problem.
use disabled = true / false;
Cheers.

thanks for the answers...
but it not a syntax problem... in my question is a write error... sorry...
this is the right source code:
function enableField() {
alert('sdf');
document.getElementById('ctl00_MainPlaceHolder1_TextBox1').disabled = false;
}
hmmm..... i dont know.... f*** js
|
|
|
|
|
i think you should also try
document.form1.txt1.readOnly=true;
hope this will work for you

Hi all
I have Ajax enabled website. Its working fine in my local server (Ajax animation effects are working) but on the server its not working. Pages showing javascript error 'sys' not defined'.
I have added ajax dlls and System.Web.Extensions.dll into website's bin folder.
but does not work.
Many post suggests adding httphandlers and httpmodules like...
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false"
type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions,
Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add verb="GET,HEAD" path="ScriptResource.axd"
type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions,
Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
validate="false"/>
</httpHandlers>
After adding httphandlers, it starts showing 500 - Internal server error.
and if I remove httphandlers section, it start working but ajax animation does not work.
Have any idea?

Hi
I have a user control, which contains a button and gridview. When the user control is loaded in the browser it runs without error. However, when I click the button the button and the gridview simply disappears off the page.
When I view the page on the screen in view source, I noticed that the button doesn't have a unique id. Therefore, I think this may be my problem. Further, when I add a break point to the button, and run in debug mode, the break point is never reached!
The user control that I am having trouble is added to a collection object, which is also itself a user control. The collection object, when I add a button to it directly is fine.
Has anyone come across this problem before? Is the problem unique ids? If so, how do you assign unique ids to user control, and ensure uniqueness when the control is added to a collection?
|
|
|
|
|
ASP.NET takes care of creating unique IDs for each control but prefixing the id of the contained control as appropriate; mycontainer$ctrl01$myButton for instance.
It sounds as though you are having an problem with event bubbling. The click event may be being handled by a parent control.

|
|
|
The user control is being added dynamically.
Which I need to do, and is probably why the unique ids are not being correctly.
Is there away round this?

Question:
I would like to take out this link from the loginview and move it to one of the links under a RoleGroup. After doing this, nothing seems to happen when Register link is clicked on.
Any thoughts please?
thanks
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<tr>
<td>
<span>You are not logged in.</span>
</td>
</tr>
<tr>
<td>
<asp:HyperLink runat="server" ID="registerLink"
NavigateUrl="~/Register.aspx" Text="Register"
ToolTip="Go to the registration page"
/>
</td>
</tr>
</AnonymousTemplate>

Please read the forum guidelines. "Login" is not a very descriptive or informative title.
What do you mean nothing happens? You are not redirected to the registration page?

you, you are right. I do not get redirected.
It only redirects when the html of the register page is inside the loginview.
Thanks

I want to create a dynamic report. In my report rows and columns are not fixed, out put should displayed in a grid view.I have one filtration criteria in which i will specify rows and columns.I can add multiple rows and columns.

Hello Friends,
I've a textbox and Button As i click on button it should generate a new row to insert and insert the data into GridView's row from textbox.
Actually i've to save the data into gridview and finally into database from gridview.
|
|
|
|
|
The simplest thing you can do is cast the DataSource of GridView to a DataTable, add a new row to DataTable from TextBox and bind it to GridView on ButtonClick.

Oh, i thought his TextBox and Button are outside Grid.
