Call client side and server side events together.
I have one textbox on my aspx page.
I want to validate amount in that textbox. If it exceeds 100 then the alert message should show that amount is bigger.
And it should not go further. But if the amount is less than or equal to 100, then after checking the condition on
clientside, it should to the server side TextChanged event.
I have written a javascript function which is being called on "onchange" event of textbox and if the value is valid, then
it should call serverside textchanged event of the same textbox.
Please its urgent.

It you are trying to validate it on server side too, then use compare validator.
It can validate that text box on first on client and then on server.
==========================================================
<asp:CompareValidator ID="CompareValidator1" runat="server" ControlToCompare="TextBox1"
Display="Dynamic" ErrorMessage="CompareValidator" Operator="LessThanEqual" SetFocusOnError="True"
ValueToCompare="100"></asp:CompareValidator></div>
Hope it helps.

Or try this:
<script type="text/javascript">
<!--
function validateTextBox(elementRef)
{
var textBoxValue = parseInt(elementRef.value);if ( (isNaN(textBoxValue) == true) || (textBoxValue > 100) )
{
alert('Too large!');
elementRef.focus();
elementRef.select();
}
else
{
__doPostBack(elementRef.id, '');
}
// -->
</script>And in the CodeBehind file:
private void Page_Load(object sender, System.EventArgs e)
{
// Insure that the __doPostBack() JavaScript method is created...
this.GetPostBackEventReference(this, string.Empty);TextBox1.Attributes.Add("onchange", "validateTextBox(this);");
}NC...

I would like to know how to raise an event on a client side only control from a server side function. For example, I have Button1 whose onclick is handled at the server.

All I need to do is automatically click the anchor after I post back from the Button1.click event.I tried the following line of c...
Is it possible to call client side function from server side code without initial client request?
Atlas is great. I'm using timer to periodically check database changes on server to populate client side controls with new data.

Server should call client side function on all connected clients when, for example, 'database updated' event occurs on server. Thanks.

Client Side events and Server side binding
I want to filter a dataset, server side and bind it to a select control. Problem is my filtering must be done based on the text written by the user in a text input. To get this text i'm using client side keyboard events. I tried to use client side binding and it works fine, but the problem is my dataset has more than 10000 rows, and so the performance is awful. Only thing i can do i think is to rebind the select control to a filtered dataset, improving performance.

For example, if I'm going to put an HTML table on a page, how do I decide whether or not to use a server control? Should the server side always be chosen or if there is not explicit server side functionality required is it better to opt for a "normal" client side table?
