Hi
I am looking for a solution to a Java Script question. My question is this, I have a gridview, and in this gridview I have a column, which I use as a flag. The gridview itself is dynamically added to a user control and then to the page. What I would like to do is to use Java Script to hide this column, but I do not know how to do this. Unfortunately, I cannot use code behind, because of the gridview being dynamically added.
Also, I have one further question, I already have some Java Script code that can hide some of the rows based upon the values in my column when a button is clicked. What I want to do is when the page is loaded for the first time, to hide some of these rows, and to use the button in reverse to reveal them again. How do I achieve this?
Thanks

Look at the JQuery [^]library, it makes tasks like this very easy.
$("td.flag").hide();
This simple bit will hide any TD element with the class name flag.

I just had a quick look at this, and I am slightly confused as to how I can use JQuery to hide the rows when the page is first loaded; then to use a button show them, or hide them based on a click. Please explain.

Have you read the documentation for JQuery?
$(document).ready(function()
{
$("tr.hidden").hide();
$("button").click(function(){ $("tr.hidden").show(); });
}
This script will run when the page is loaded and hide any TR element with the class hidden. It will also hook up the click event of the button to show all TR elements with the class hidden when clicked.

Hi
Yes, I had a brief look at the article, and I got the general idea. You to excuse my ignorance, but I have never used JQuery before. So, it take me a few days to get use to it.
However, in my current JavaScript, I have a function which I have called ShowAll. This function does the reverse what I really want to do. To get to my gridview, I am using getElementByID to find the div where the gridview I want to use is located, and then childNodes for the gridview I want. To get to the rows, I am using getElementsByTagName to find all the rows, and then a for loop with an if for the logic.
So, my question is whether I can nest the JQuery into the JavaScript to work with the gridview I want. Is this possible?

One, it is an entire website, not an article. Two, take a better look and your question will be answered.
Your JavaScript, as you describe it, is convoluted and unnecessary and shows a lack of understanding about how to use JavaScript.

Hi
I am not sure what has happened here, but I have 3 panels, and these 3 panels are nested inside one large, thus:
<asp:panel id="pnlMain" runat="server" height="60%" width="100%">
<asp:panel id="panel1" runat="server" height="100%" width="100" scrollbars="vertical">
<asp:panel id="panel2" runat="server" height="100%" width="100" scrollbars="vertical">
<asp:panel id="panel3" runat="server" height="100%" width="100" scrollbars="vertical">
What is happening is that when I add my gridviews to these nested panels, the panel is just getting larger, the scroll bars are not scrolling, in other words the panels are stretching rather than their height staying fixed.
How do I fix this?
Thanks

Because you are specifying the heights to be a percentage, not a fixed size. It's doing as you have asked.

Wouldn't setting the size as a pixel stop the panel fitting any browser size resolution?

You can't have it both ways

you can attach onclick event on label and textbox at server side as below
Label1.Attributes.Add("onclick", "javascript:alert('you have pressed Label')");
TextBox1.Attributes.Add("onclick", "javascript:alert('you have pressed Textbox')");Cheers!!

| In the OnRowCreated event, assign the javascript click event and send the row index to it. That index you can then access in the server side click event through a hidden field. "No matter how many fish in the sea; it will be so empty without me." - From song "Without me" by Eminem

Use a button column and you don't need to do any of this.

Use a button column or template column and specify the onclick even handler for client-side processing or handle the event on the server-side
