I'm developing a web application using asp.net and bootstrap v3. On my page, there is a modal which contains two twxt boxes and an asp dropdownlist. My problem is that the dropdownlist SelectedIndexChanged is not firing. When I put a dropdownlist outside the Modal, its SelectedIndexChanged fires without any problem. I have set the EnableViewState="true" for the Page and the DDL. I have also set AutoPostBack = "True". Note: The page postback when i change the selected item in the DDL inside the modal but it don't go to the SelectedIndexChanged event as i have put a break point and it doesn't work. I have notices also that the HTML of the DDL (Option, Select) is also that the (Selected="Selected") property is always set for the first element.
this is how I loadt the DDL
protected void Page_Load(object sender, EventArgs e)
{
if(!isPostBack)
{
DataSet ds2 = MainModule.GetTableSQLBySP(new Dictionary<string, string>(), "SP_Stand_GetSectorTypes");
ddlMdlAreaInvitedSecType.DataSource = ds2.Tables[0];
ddlMdlAreaInvitedSecType.DataValueField = "Set_ID";
ddlMdlAreaInvitedSecType.DataTextField = "Set_LongName";
ddlMdlAreaInvitedSecType.DataBind(); }
}
and this is the Modal code
<div class="modal fade" id="modalAreaInvitedSearch" style="margin-top: 155px" role="dialog" aria-labelledby="basicModal" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
