Error when using ScriptManager to close current window and open another one

I have a problem when executing below line of code, I want to show success message and then closing the current window and open another one.

ScriptManager.RegisterClientScriptBlock(this, this.GetType(),
"alertMessage", "alert(' Progress Has Been Finished '), 
window.close(), window.open('ReqProgDetail.aspx?v=0&codLic="+ 
Convert.ToInt32(_idlicense) + "#section1') ", true);

My HiddenField :

HiddenField _idlicense = (HiddenField)dv.FindControl("hid_id_license");

and this is my exception message :

System.InvalidCastException: Unable to cast object of type 
'System.Web.UI.WebControls.HiddenField' to type 
'System.IConvertible'. 
at System.Convert.ToInt32(Object value)

You're getting an error because you're trying to convert HiddenField object into int, so you have to retrieve value in HiddenField object first before converting it to int.

try changing part of your code:

Convert.ToInt32(_idlicense)

into :

Convert.ToInt32(_idlicense.Value)
