Why OnClick event of a button inside usercontrol not happening

Greetings to all the ASP.NET pros out there

I have a problem that i would like to share with you and if possible get an advice:

I am loading a usercontrol dynamically using datalist. inside this usercontrol i have a imgbuttton.

in order to find the specific usercontrol who's button was clicked, iam trying to assign a customized ID to the userControl, and the button like this:

Setting the id for the UserControl:

protected void Page_Load(object sender, EventArgs e)
    {
        i++;
        this.PreRender += new EventHandler(Cast_PreRender);
        this.ID = "Result" + i.ToString();
    }

Setting the id for the button

void Cast_PreRender(object sender, EventArgs e)
    {
        PlayerName1.Text = Player1NameSB;
        PlayerName2.Text = Player2NameSB;
        CasterName.Text = CasterNameSB;
        ImageRace1.ImageUrl = Race1SB;
        ImageRace2.ImageUrl = Race2SB;
        Map.Text = MapSB;
        GameFrame.Text = GameFrameSB;
        LikeAmount.Text = LikeAmountSB;
        CasterLOGOIMG.ImageUrl = CasterLOGO;
        PlayButton.ID = i.ToString();
        
    }

the problem is, after doing this, when i click the button nothing happens, i mean, when debugging, i never get inside the OnButton_Click event. if i delete the --> this.ID = "Result" + i.toString(); and the--> PlayButton.ID = i.ToString(); it's ok. here is the onClick code

protected void PlayButton_Click1(object sender, ImageClickEventArgs e)
    {
        
        Image img = (Image)sender;
        string tt = img.ID.ToString();
        Response.Redirect("default2.aspx");
       // lb.Text = img.ClientID;
        
    }

if there anything elese you might need to evaluate my problem, ill gladly prove and additional code needed.
thank you very much for your help,

If you move the assignment of the ID for the PlayButton from the PreRender to the Load event it will probably work.

hi mm10, thanks for your response,

this is not working

i have it written like this

protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack == false)
        {
            i++;
            this.PreRender += new EventHandler(Cast_PreRender);
            PlayButton.ID = i.ToString();
            this.ID = "Result" + i.ToString();


        }
        
    }

still nothing happens, it is not getting to the onclick event. any other ideas?

Re: Why OnClick event of a button inside usercontrol not happening

Set it on every request to make it work on the first postback:

protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack == false)
        {
            i++;
            this.PreRender += new EventHandler(Cast_PreRender);
            this.ID = "Result" + i.ToString();
        }
PlayButton.ID = i.ToString();

    }

Re: Why OnClick event of a button inside usercontrol not happening

where have you declared the variable "i"

Re: Why OnClick event of a button inside usercontrol not happening

hi again,

the postback condition is not the problem, i dont know what is, but for sure is not the postback, i added this condition just now.

ofcourse i tried what you suggested, nothing new there.....:)

Re: Why OnClick event of a button inside usercontrol not happening

hi nirman, thank you for your response...

Here the declaration of the "i":

public partial class SearchBullet : System.Web.UI.UserControl
{
    public static int i = 0;
    private string casterLOGO;

    public string CasterLOGO
    {
        get { return casterLOGO; }
        set { casterLOGO = value; }
    }

in addition, this is the aspx page where i load the user control, may this has to do with the problem:

<asp:DataList ID="WatchLaterDL" runat="server" DataSourceID="SDSWatchLater" RepeatColumns="1">
                    <HeaderTemplate>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <Search:Bullet runat="server" EnableViewState="false" ID="SearchResults" Player1NameSB='<%#Bind("Player_Name") %>'
                            Player2NameSB='<%#Bind("Expr1") %>' CasterNameSB='<%#Bind("Caster_Name") %>'
                            Race1SB='<%#Bind("Race_1") %>' Race2SB='<%#Bind("Race_2") %>' MapSB='<%# Bind("Map")%>'
                            GameFrameSB='<%#Bind("Game_Frame") %>' LikeAmountSB='<%#Bind("Like_Amount") %>'
                            CastURLSB='<%#Bind("Cast_URL") %>' CasterLOGO='<%#Bind ("Caster_LOGO") %>' />
                    </ItemTemplate>
                    <SeparatorTemplate>
                        <br />
                    </SeparatorTemplate>
                </asp:DataList></div>

thanks again for your help

Re: Why OnClick event of a button inside usercontrol not happening

my solution was like this:

instead of using an image buttom, i used Hyperlink.

on_Load event of the usercontrol, i assigned to the src Attribute of the hyperlink all the properties of my user control and passed those using

querystring to another page.
