Question

I added a web user control and created a function in jquery at client side named “ButtonClick” on web user control. And calling this method from code behind using ScriptManager.RegisterStartupScript in loop .
But it runs only one time, while it should run loop times.

Please help me……
Code sample is here

  var q = (from p in obj.Pinny_ShowOffer where (p.OfferID == objOffer.OfferID) select p).ToList();
    if (q.Count > 0)
    {
        Rdbtnoffersetup.Items.FindByValue("2").Selected = true;
        ScriptManager.RegisterStartupScript(Page, Page.GetType(), "ShowDIv", "ShowDiv(2,2);", true);
        Int32 k = 0;
        for (Int32 i = 0; i < q.Count; i++)
        {
            ScriptManager.RegisterStartupScript(Page, Page.GetType(), "ButtonClick",
                                                                        "ButtonClick('btn" + q[i].Weekday + "','" + q[i].Weekday + "');", true);
            if (q[i].StartTime == "07:00" && q[i].EndTime == "11:00")
            {
                ScriptManager.RegisterStartupScript(Page, Page.GetType(), "select value", "SelectValueoFDropDown('drpStart" + q[i].Weekday + k + "','1');", true);
            }
            k++;
        }
    }

The reason it’s only firing once is because you’re duplicating they key ButtonClick in your RegisterStartupScript call.

From the documentation:

A client script is uniquely identified by its key and its type.
Scripts with the same key and type are considered duplicates. Only one
script with a given type and key pair can be registered with the page.
Attempting to register a script that is already registered does not
create a duplicate of the script.

You could trying something like this instead to keep it unique:

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "ButtonClick" + i.toString(),"ButtonClick('btn" + q[i].Weekday + "','" + q[i].Weekday + "');", true);
