Use RequiredFieldValidator.
Add a RequiredFieldValidator and set the property ControlTovalidate as your textboxname , set the appropriate error message on ErrorMessage property

no i cannot use requiredfieldvalidator . I want to have clint side interaction;requiredfieldvalidator works on
server side .Something in javascripting ?????????
|
|
|
|
|
No buddy. It works in client side.
Anyway the javascript code for mandatory text field is here
function RequiredField()
{
document.getElementById("lblErrormessage").innerText = '';
if(document.getElementById("TextBox1").value == '')
{
document.getElementById("lblErrormessage").innerText = "Field is required";
return false;
}
return true;
}
add this method in Page_Load event code bahind on some submit button onclick like
button1.Attributes.Add("onclick","return RequiredField()");

Of course, "Textbox1" won't work, as the framework assigns it's own Id, based on where the control is in the page heirarchy. You're definately better off using the validators, which do indeed work on the client.

when i fill up now the textboxes it is not getting submitted.
|
|
|
|

why are you changing your code yourself.
see my code for text box as
if(document.getElementById("TextBox1").value == '')
but you changed as innerText.
for textbox its value
for label its innerText
ok

Hi
1.My local host is not displaying default page
2.if I create any aspx file I am getting this problem that the specified webserver not running on Asp.Net version 1.1
Pls find the attached screenshot .
|
|
|
|
|
This is what you should check to se so the IIS has .NET properly installed.
1. Open IIS Service Manager.
2. Right click the Default Web site and select Properties
3. IF you have a tab called ASP.NET, click that to se what version is installed and activate the one you need to run if you have multiple alternetives.
--- IF you don't have a ASP.NET tab visible or it's inactive. You need to re-install the .NET framework or simply run the aspnet_regiis.exe command found in the .NET's bin directory under \WINDOWS\Microsoft.NET\Framework\vx.xxx.xx
4. IF you have .NET properly installed and activated under the IIS, then you have to check so the website or virtual directory you are trying to access has the Application Settings enabled so it can act as a ASP.NET Application.
5. IF that dosen't help and you are using Windows Server 2003 >, you must check the security settings
found under the Web Service Extensions node, Make sure the ASP.NET vxxx.xx is Allowed and that any other extension you plan to use also is enabled.
Hope that will help you find/solv the problem(s)

hi
You can use two calendar controls like
In your Form,have
From Date[as Label] -- [have a Textbox here]--Calendar Control1
To Date[as Label] -- [have a TextBox here]--Calendar Control2
Search[as Button]
Assign the date you have selected in the Calendar control to the respective textboxes and Search accordingly.
Similar samples are available in this site itself.
One of it is Here http://www.codeproject.com/aspnet/RayCheng_MyCalendar.asp[^]
~Happy Coding

Well, I tried formatting the listbox to give the appearance
of columns like :
xxx.....bbbb...dddd )I had to add "."s here!)
111.....22.....333
but no matter what, setting DataTextString="{0,-18} or
anything else, it strips out padded spaces:
xxx bbbb dddd
am I barking up the wrong control tree? Maybe a datagrid?
The box is filled from a: DataSet.Table("aa")..
using Vis Studio 2005..
ALSO..the TextChanged and SelectedIndexChanged dont fire until
I hit a button which causes postback..??
Thanks for helping..
