Asp.net dropdownlist Onselectedindexchanged event

Question

I have some dynamic controls in my asp.net page.

like,

TextBox ratingtxtbox = new TextBox();
ratingtxtbox.ID = "Rating_1";

and

DropDownList Exsecondpositiontxtbox = new DropDownList();
Exsecondpositiontxtbox.ID = "Exacta2nd_" + i.ToString();

For my textbox I'm added keyup event as

ratingtxtbox.Attributes.Add("onkeyup", "ChangebyWin(" + i.ToString()+")");

Its perfectly working..

Now I added indexchanged event of dropdown list as

Exsecondpositiontxtbox.Attributes.Add("onselectedindexchanged", "ChangebyExacta(" + i.ToString() + ")");

But it not working.. Is it the error in Key name..?

You really need to share your javascript code as well. Also are you using ClientIDMode=Static on those controls? As that won't actually be the ID unless you are. — mattmanser

You should use onchange instead. OnSelectedIndexChanged is a server-side event

Exsecondpositiontxtbox.Attributes.Add("onchange", "ChangebyExacta(" + i.ToString() + ")");

Here is how you would use OnSelectedIndexChanged

Exsecondpositiontxtbox.SelectedIndexChanged += SomeEventHandler;

Exsecondpositiontxtbox.Attributes.Add("onchange", "ChangebyExacta(" + i.ToString() + ")");
