Yes, you can manage on your own to create chart in the ASP.NET like the example from the article[^], however IMO you'd better use a third party component which may save lot of your effort, for example the DundasChart. If you're not familiar with a third party component, you might want to contact thier support team, and I think they're more than willing to give you a hand to integrate the component into your application.

Hi,
I am new to Biztalk server. Can any one explain me what is Biztalk server and what is the relation between Biztalk and .Net?

Hi there,
I guess the ASP.NET forum is not a place to look for your answer, try the Biztalk Home[^] instead.

Hi,
You can use javascript to validate the dropdown list. What you need to do is just call a javascript function on onChange event of the dropdown list and and perform the validation in that function.

plz chek it out i hv write this javascript is it correct or wrong
function get_selected()
{
// document.Form1.
var theContent=document.getElementById ("DropDownList1").sourceIndex;
//var theContent=document.getElementById("DropDownList1")
if (theContent="[SELECT ONE]")
{
window.alert("Select all the value from the dropdownList");
}
}
|
|

|

if the dropdownlist control is inside the datagrid control then you can't access the dropdownlist id like that. Because the id will be changed after rendering. you can send that as parameter and then use it.

All the validators support the client side validation, expcept that you are using the ASP.NET 1.1 with non-Microsoft browsers.
By the way, can you write your reply in full instead of using the SMS style.

Hi,
I have a good amount of mail templates from which i just read the contents and send it as a mail, and all the templates are written in .TXT file.
Now i want to do the same thing in a different manner that is , i want to read the same .TXT file and append the logged in user name somewhere in the file.
I have completed the base of how to send the mail but i am stuck up of how to modify the contents dynamically.
I dont want to save the modified file, i just want the name to be included.
I wish if something can be done in StreamReader when i read the contents in this object.
Thanks in advance.
