You can try below code:
function isNumberKey(i) {
if (i.value.length > 0) {
var notNumber = /[0-9]/g;
if (i.value.match(notNumber)) {
i.value = i.value.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,");
}
}
}
The result:

When you enter 333333, the key cannot be released. The keyup event is sent to an element when the user releases a key on the keyboard.

I have already answered in the above post. The keyup event is sent to an element when the user releases a key on the keyboard.
So when you type, you can only keep pressing the keyboard, not release.

I tried with two your solutions, but not effect (user can input letter and group like as 3,3,333,3).
I have alot of textbox like money, so i want buld one function and call as onkeyup="isNumberKey(this);".
My function is activities very good, exception left, right, home, end key are no effect.
I want allow user typing only number AND left, right, home, end key.
this is my function:
function isNumberKey(i)
{
if (i.value.length > 0)
{
i.value = i.value.replace(/[^\d]+/g, ''); // Only number
i.value = i.value.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,"); // group for currency
I tried with two your solutions, but not effect (user can input letter and group like as 3,3,333,3).
This is the test result of my last answer, does this meet your needs?
The ValidChars property in the FilteredTextBoxExtender control will let you set the characters you need to type.

Use F12 to check whether there is an error message in the console.
Please show me your complete code.

Hi test0101,
You can use RegularExpressionValidator control to make textbox only input numbers.
<asp:TextBox ID="Money" onkeyup="isNumberKey(this);" type="tel" runat="server"></asp:TextBox> <asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="Money" runat="server" ErrorMessage="Only Numbers allowed" ValidationExpression="\d+"></asp:RegularExpressionValidator>When you enter 333333, the key cannot be released. The keyup event is sent to an element when the user releases a key on the keyboard.

Hi test0101,
If you want to allowing only certain characters in a TextBox, you can try to use ajax control FilteredTextBoxExtender.
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:TextBox ID="Money" onkeyup="isNumberKey(this);" runat="server"></asp:TextBox> <ajaxToolkit:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" runat="server" TargetControlID="Money" ValidChars="1234567890," />I have already answered in the above post. The keyup event is sent to an element when the user releases a key on the keyboard.
So when you type, you can only keep pressing the keyboard, not release.

Yes Sam.
This is my code: https://forums.asp.net/post/6301104.aspx
In that code, already:
<asp:ScriptManager id="toolScriptManageer1" runat="server" EnablePartialRendering="false">
</asp:ScriptManager>
so, I only updated your help with:
<asp:TemplateField HeaderText="Salary1" >
<ItemTemplate>
<asp:textbox ID="txtSalary1" onkeyup="isNumberKey(this);" Text='<%# Eval("MySalary1") %>' Width="80px" runat="server"></asp:textbox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Salary2" >
<ItemTemplate>
<asp:textbox ID="txtSalary2" onkeyup="isNumberKey(this);" Text='<%# Eval("MySalary2") %>' Width="80px" runat="server"></asp:textbox>
<ajaxToolkit:FilteredTextBoxExtender ID="FilteredTextBoxExtender2" runat="server" TargetControlID="txtSalary2" ValidChars="1234567890," />

Hi test0101,
I read all your code, then wrote a demo based on your code, but it is still work.
This is my tested code:
<script> function isNumberKey(i) { if (i.value.length > 0) { var notNumber = /[0-9]/g; if (i.value.match(notNumber)) { i.value = i.value.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,"); } } } </script> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"> <Columns> <asp:TemplateField HeaderText="Salary1"> <ItemTemplate> <asp:TextBox ID="txtSalary1" onkeyup="isNumberKey(this);" Text='<%# Eval("MySalary1") %>' Width="80px" runat="server"></asp:TextBox> <ajaxToolkit:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" runat="server" TargetControlID="txtSalary1" ValidChars="1234567890," /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Salary2"> <ItemTemplate> <asp:TextBox ID="txtSalary2" onkeyup="isNumberKey(this);" Text='<%# Eval("MySalary2") %>' Width="80px" runat="server"></asp:TextBox> <ajaxToolkit:FilteredTextBoxExtender ID="FilteredTextBoxExtender2" runat="server" TargetControlID="txtSalary2" ValidChars="1234567890," /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> </ContentTemplate> </asp:UpdatePanel>Have you used F12 to check if there is an error message in the console? and you can also set a breakpoint to debug whether your js method is triggered.
