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.

// document.Form1.
var theContent=document.getElementById ("DropDownList1").sourceIndex;
//var theContent=document.getElementById("DropDownList1")

{
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.

+ You can place a special text holder like <LoggedInUserName>, you then simply replace it with the real username value.
+ You can place the format item like {0} ... in the contents, and use the String.Format method to insert the username value.

hi,
thanks for the reply, i am sure both the methods are beneficial.
but can you please tell me how to use String.Format, and which one is more convenient to use.

Not sure, but I'd go for this method.

You can use checkboxlist control to generate the checkboxes dynamically. you can assign source to the checkboxlist control and bind that to make it ready for use.

Hi there,
Are you sure that you need dynamic checkbox controls? Anyway, you can find lots of datagrid examples from the datagridgirl[^] site

I can't able to find the syntex for DESC order which fits in my problem. I am using following syntex. but where should & how should i include the key word DESC in my coding line.Thanks,
dataview.sort=dataset.tables[index].columns["columnname"].tostring();

You simply concatenate the DESC keyword after the column name:
dataview.sort=dataset.tables[index].columns["columnname"].tostring() + " DESC";
|
|
|
|
|
When I concatenate the DESC keyword after the column name, It's not returning any value to Datagrid. I tried the same syntex.
Thanks,
NIKI
