Create a subsite programatically and add SPGroups

SPSecurity.RunWithElevatedPrivileges(delegate()

{

using (SPSite osite = new SPSite(siteCollectionUrl))

{

using (SPWeb oweb = osite.OpenWeb())

{

SPWeb site = null;

site = oweb.Webs.Add(Weburl, projectname, projectdescription, EnglishLocaleId, sitetemplate, true, false);

site.Navigation.UseShared = true;

site.Update();

isSitecreated = true;

if (isSitecreated)

{

site.AllowUnsafeUpdates = true;

site.SiteGroups.Add(site.Name + "-Owners", site.CurrentUser, site.CurrentUser, "");

site.SiteGroups.Add(site.Name + "-Visitors", site.CurrentUser, site.CurrentUser, "");

site.SiteGroups.Add(site.Name + "-Members", site.CurrentUser, site.CurrentUser, "");

SPGroup gOwners = site.SiteGroups[site.Name + "-Owners"];

SPRoleAssignment assignmentOwner = new SPRoleAssignment(gOwners);

assignmentOwner.RoleDefinitionBindings.Add(site.RoleDefinitions["Full Control"]);

site.RoleAssignments.Add(assignmentOwner);

SPGroup gVisitors = site.SiteGroups[site.Name + "-Visitors"];

SPRoleAssignment assignmentVisitors = new SPRoleAssignment(gVisitors);

assignmentVisitors.RoleDefinitionBindings.Add(site.ParentWeb.RoleDefinitions["Read"]);

site.RoleAssignments.Add(assignmentVisitors);

//Add users for visitors group

//gVisitors.AddUser();

SPRoleDefinition roleDefinition = site.ParentWeb.RoleDefinitions.GetByType(SPRoleType.Contributor);

SPGroup gMembers = site.SiteGroups[site.Name + "-Members"];

SPRoleAssignment assignmentMembers = new SPRoleAssignment(gMembers);

assignmentMembers.RoleDefinitionBindings.Add(roleDefinition);

site.RoleAssignments.Add(assignmentMembers);

 site.AllowUnsafeUpdates = false;

}

 else

{

  isSitecreated = false;

 }

}

}

});

 This will help you to create site and groups programatically

Bind values into dropdown list using SQL table.

Bind values into dropdown list using SQL table.

SqlCommand Bicmd;

SqlDataAdapter BiAdap;

DataTable BiDt;

 private void bindApplication()
        {
            try
            {
                SqlConnection con = new SqlConnection(connStr);
                con.Open();
                Bicmd = new SqlCommand("select Application as Name from WFE_ApplicationMaster", con);
                BiAdap = new SqlDataAdapter(Bicmd);
                BiDt = new DataTable();
                BiAdap.Fill(BiDt);
                ddlApplication.Items.Clear();
                ddlApplication.DataSource = BiDt;
                ddlApplication.DataBind();
                ddlApplication.DataTextField = "Name";
                //ddlApplication.DataValueField = "ID";
                ddlApplication.DataBind();
                ddlApplication.Items.Insert(0, "--Select--");
                BiAdap.Dispose();
            }
            catch (Exception)
            {
             
                throw;
            }

        }

This will help you to bind values from SQL table to dropdown list

Radio button list validation using JQuery.

Radio button list validation using JQuery.

<asp:RadioButtonList ID="rbIsactive" CssClass="radioButtonList" RepeatDirection="Horizontal" runat="server" ValidationGroup="g">

<asp:ListItem Value="0">Active</asp:ListItem>

<asp:ListItem Value="1">In Active</asp:ListItem>

</asp:RadioButtonList>

if ($("[id$=<%=rbIsactive.ClientID%>]").find("input:checked").length < 1) {
            var RB1 = document.getElementById("<%=rbIsactive.ClientID%>");
            var radio = RB1.getElementsByTagName("input");
            for (var i = 0; i < radio.length; i++) {
                if (radio[i].checked) {
                    break;
                }
                else if (i == radio.length - 1) {
                    rvalue = false;
                    alerts = "Please Select Workflow Status";
                    radio[0].focus();
                }
            }

        }


This will help you validate radio button list

Remove spgroups using powershell.

Remove spgroups using powershell.

When you delete a site spgroups for that site will remain in webapplication itself. So we have to remove that spgroups manually. Otherwise it will return "Group name already exist" exception when you create a spgroup with same/old name.

$spWeb = Get-SPWeb "Web Url"
$spGroups = $spWeb.SiteGroups

$groups = ("MID-10000-Owners", "MID-10002-Visitors","MID-10003-Members")

ForEach($group in $groups) {
   $spGroups.Remove($group)
}

$spWeb.Dispose()

This will help you to remove spgroups using shell command.
