I set breakpoint in the Foo2 function (comment), but debugger hasn't visited it. I tried writing diffrent text, not writting anything and writting "bar" and pushing enter and tab after that, but it still doesn't work. I mean text changing action. Is it possible?
There's no submit button. You need to add a button to submit the form, which will then trigger page validation.
<asp:Button runat="server" id="myButton" Text="Submit" />

when include JQUery the InnetHTML is not working. Where is the error and how to fix it.
Thanks in advance
i believe it is because you are using runat="server" in head within which you add the jquery. jquery and javascript for client side, and runat="server" posts the data to server. remove runat="server" from head and check.
I want this gridview to emulate a console, the text file I have is a server console log.
I want it to:
*Refresh when the file changes.(thus the timer)
*Scroll bar position maintained when updated, unless at bottom.
*When scroll bar position is at the bottom,stay at the bottom after databind update.
Current Problem: On timer, databind() moves the scrollbar position back to the top, and with a refresh so often you can't even scroll down at all.
Here is my current code. Thank you for your help!

LinkButton senderLink = sender as LinkButton;
//store requested language as new culture in the session
if (senderLink.CommandArgument == "he-IL")

}
else
{
// some code
}
Session[Global.SESSION_KEY_CULTURE] = senderLink.CommandArgument;
//reload last requested page with new culture
Server.Transfer(Request.Path);
}
}
In your code behind:
this.html.Attributes.Add("dir", "ltr");
An alternative, if this is not working is to place the attribute directly on the tag and use a property to populate it:
<body dir="<%:Dir%>">
public string Dir { get; set; }
// Set Dir in the on click event
protected void RequestLanguageChange_Click(object sender, EventArgs e)
{
LinkButton senderLink = sender as LinkButton;
//store requested language as new culture in the session
if (senderLink.CommandArgument == "he-IL")
{
Dir = "rtl";
}
else
{
Dir = "ltr";
}
Session[Global.SESSION_KEY_CULTURE] = senderLink.CommandArgument;
//reload last requested page with new culture

I have a button in my asp.net web application. When i clicking the button it will hide the text box in the same webs application .
If is it possible that anyone help me its very useful
Thank you
If the button is an html button then you can use javascript to do this:
onclick of button call following js:
document.getElementById(textBoxId).style.display = "none";
or
document.getElementById(textBoxId).style.visibility = "hidden";
from code behind TextBoxId.Visible = false;
from Javascript document.getElementById('<%=TextBoxId.ClientId%>').style.dispaly="none";
You can do it with JQuery:
<script>
$("#myButton").click(function () {
$("#myTextBox").hide("slow");
});
</script>
This is what you are looking for:
HideTextBox.aspx

The same problem I faced several times the cause is that java script cannot call code behind(c#/vb function/events).
An alternate way I used is to use hidden fields that is accessible by both java script and code behind. But then you want to call events not read values modified by java script.
For this we refreshed the page through java script when we want to trigger that code behind event and let the page load to monitor the scenario(value that java script set) and triggers the required event.
The code at the end would be real mess and unmanageable, would take lots of efforts to debug.
