Gridview Rowcommand event firing but show hide controls including Gridview not happening

Question

Here is what I am trying to do in two simple steps:

1) New Row (trNewPost) which has table inside and controls in it to add new post or to update existing post.

Default Visible=false;

2) Add Button to make above row visible = true;

3) trMyPosts has Gridview in it and displays all the posts.

Default visible = true.

When user click on editing any row of the gridview (RowCommand event) I just want to hide this grid (trMyPosts) and show trNewPost.

That's all. events firing, but nothing happening.

What technologies are you using? Is this Desktop or browser based? Language? Framework? We need to know more before we can help — Binary Worrier, Jun 28 '11 at 15:12

I think you've got viewstate problem.

One of the things you can do is this :

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            // do things here
        }
    }

Because whenever anything happens, the page posts back. By encapsulating your Page_Load with ! Page.IsPostBack, you prevent those things from happening over and over again.

Now, if your variable is a global variable, you will have this same problem. Consider instead using a Session variable.

Also, I just wanted to show you this piece of code just in case :

    protected void HideShowClicked(object sender, EventArgs e)
    {
        // toggle the visibility of the control
        // (that is, if visible then hide, if hidden then show) 
        myControl.Visible = ! myControl.Visible;
    }
