The thing is if DropDown Autopostback = true, the page will be posted back to the server. It will generate Page_Load event and the respective DropDown.SelectedIndexChanged event.

As I can see you have populated Dropdown inside the !IsPostBack statement, I think the post back event will not run any line from Page_Load (Which I think is perfect).

The only reason that may come, if you have written something inside dropdown.selectedIndexChanged event which changes the original selection with the initial value.

Please check if PopulateDDL1 is called from elsewhere or not.

Hi,

There is a web form and after user select certain option - the page reloads.
There are like 3-4 such options where page reloads according to the user selection but everytime after page reloads - page focus moves to the top. But i want that to the same loaction where user select that option.

You have to use Ajax. in your Visual Studio toolbox there is a Ajax Section and the is an Update panel. Please Google Update panel.

after finishing that option set the focus to the desired location by using focus() method.

video gallery problem...

Hi to all,

I am working on asp.net web application. In this there is a module "video gallery". It should be database driven. I did this by using a flash player. Everything was working fine in the development enviroment ie on localhost. When I uploaded it to the server, the flash player is not visible on the page. Then I checked the "view source" and the control is something like this:

<br />
<div id="FlashVideo1"><br />
	<input id='FlashVideo1_objectHasPlayer' name='FlashVideo1$objectHasPlayer' type='hidden' value='false' /><script type="text/javascript"><br />

Hi Padmanabhan,

Thanks for replying. Actually the gallery is database driven. I am using hyperlinks in datalist control. When user will click any link then the corresponding video will be played in the player.

Change your code to

    {
        try
        {
            ErrorMessage.Text = "";
            cnx.Open();
            SqlCommand insertCmd = new SqlCommand("insert into CouponTransaction(CouponTypeID)values(@id)", cnx);
                        
            insertCmd.Parameters.Add("@Id", SqlDbType.int);
            insertCmd.Parameters["@Id"].Value = Convert.ToInt32(ToddlCType.SelectedValue);
                   
            insertCmd.ExecuteNonQuery();
            ErrorMessage.Text = "Records inserted successfully";
            cnx.Close();
        }
        catch (Exception ex)
        {
            ErrorMessage.Text = ex.Message;
        }

You must put a break point and check what results you get from the selected value. it might have returned an empty string that is why you got that error. You must stop assuming the input from the user is correct.

Try it and tell me what it does
