I am currently working with a text box that is embedded within a gridview. My goal is to retrieve the ID of the textbox using JavaScript. However, when I try using '<%= txtNewQty.ClientID %>', it results in a compilation error.

txtNewQty is not accessible at the top level of the page, so you won't be able to use it in that way. You may need to either generate the JavaScript on the server side or navigate down from the gridview element. Please provide some code and details about your desired outcome.
Controls embedded within Gridviews are not part of the main Page structure; instead, they are confined to the .aspx file. Due to their nature of being replicated in multiple rows, these controls are dynamically generated.
If you need to access a specific control within a Gridview row, you can utilize the FindControl method.
foreach(GridViewRow row in gridview.Rows)
{
Textbox tb = row.FindControl("txtNewQtv") as Textbox;
string id = tb.ClientID;
//Include your JavaScript code here to make it executable on the client-side
}
This code snippet demonstrates a less than ideal method by hardcoding the column index. While it may work, there is likely a more efficient solution using jQuery. Unfortunately, I do not have expertise in that area.
<script type="text/javascript">
function Update(btn) {
alert(btn.parentNode.parentNode.children[0].children[0].id);
}
</script>
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="txtNewQtv" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<input type="button" onclick="Update(this)" value="Update" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
