Please see below code below.

I am trying to create a webpart that allows a person to create sub-sites using a existing site template that's provided in a drop down list.

I get the following error when I run the code:

Error      2      The event 'System.Web.UI.WebControls.Button.Click' can only appear on the left hand side of += or -=      line 90

Error      3      The best overloaded method match for 'Microsoft.SharePoint.SPWebCollection.Add(string, string, string, uint, string, bool, bool)' has some invalid arguments         line 111

Error      4      Argument '1': cannot convert from 'System.Web.UI.WebControls.TextBox' to 'string'    line 111

Error      5      Argument '2': cannot convert from 'System.Web.UI.WebControls.TextBox' to 'string'    line 111

Error      6      Argument '3': cannot convert from 'System.Web.UI.WebControls.TextBox' to 'string'   line 111

Line 90 should say:
btn_Submit.Click += new EventHandler(btn_Submit_Click);

Open in new window

Line 111 should probably be:
SPWeb newSite = mySite.Add(txt_siteUrl.Text, txt_siteName.Text, txt_siteDesc.Text, 1033, "STS#1", true, false);
