BreadCrumb In SharePoint 2010

Breadcrumb in SharePoint:

I want to develop a breadcrumb that should have to show up the below structure.

                    Root Node-->Parent Node-->Current Node.

Approach 1:

I tried the use the existing SharePoint introduced breadcrumb.

Client side validation of ASPX server controls with Best example

This is a simple validation control at the client side using JavaScript.  Here we have to perform the server side controls validation at the client-side using JavaScript. In below “RadiobuttonList” is server control and we had to perform validation at the client-side first once button click operation performed.

Why need it /Use of it:

The button click operation will not continue/Perform if you select the  “No” option in the radiobuttonlist. For this reason, we have to perform client-side validations using JavaScript for Asp.net server controls.

<td>  <div>   <asp:RadioButtonList ID="radiobuttonList1"       CssClass=" radiobuttonList1class" RepeatDirection="Horizontal"     RepeatColumns="2" runat="Server">     <asp:ListItem Text="Yes" Value="1"  Selected="True" />     <asp:ListItem Text="No" Value="0" />    </asp:RadioButtonList>  </div> </td> <td>                               <asp:Button ID="btnSubmit" Text="Submit" OnClientClick="return   btnsubmit_OnClientClick();" OnClick="btnSubmit_OnClick" runat="server"/> </td>

var flag = true;     function btnsubmit_OnClientClick()  {          if (Page_IsValid) //server-side validation          {             var IsRequest = false;             var radioObj = document.getElementById("<%=rbNeedBBAccount.ClientID %>");             var radioList = radioObj.getElementsByTagName('input');             for (var i = 0; i < radioList.length; i++) {                 if (radioList[i].checked) {                     if (radioList[i].value == 1) {                         flag = true;                     }                     else {                      alert("Ur Request for xx  can’t be processed, as Need for xx  account field is set to NO.");                         flag = false;                     }                 }             }         }         return flag;     }

Note:

1. If you are using more than one Validation Groups in page, so you need to explicitly specify the group.
2. Best reference URL for Asp.Net Validation using JavaScript:

Adding/Removing users to/from the group:

Note: We have to check before adding/removing users to/from the group and also check the users already exists or not in group. 
 

public void AddDeleteUsersInGroup(User user)         {             string GroupName = string.Empty;             if (user.IsAdmin.HasValue && user.IsAdmin.Value)                 GroupName = "Group Owners";             else if (user.IsApprover.HasValue && user.IsApprover.Value)                 GroupName = " Group Members";             else                 GroupName = " Group Visitors";             SPSecurity.RunWithElevatedPrivileges(delegate()             {                 using (SPSite site = new SPSite(SPContext.Current.Web.Url))                 {                     using (SPWeb web = site.OpenWeb())                     {                         try                         {                             web.AllowUnsafeUpdates = true;                             SPUser spUser = web.EnsureUser(user.UserName);                             if (spUser != null)                             {                                 SPGroup spGroup = spGatingGroup(web, GroupName);                                 if (spGroup != null && (IsUserInSPGroup(spUser, GroupName.Trim())))                                 {                                    //For adding user to the group                                       spGroup.AddUser(spUser);                                    //For removing user to the group                                     spGroup.RemoveUser(spUser);                                     spGroup.Update();                                 }                             }                         }                         catch (Exception ex)                         {                             throw ex;                         }                         finally                         {                             web.AllowUnsafeUpdates = false;                         }                     }                 }             });         }

Webparts:

Web Parts are reusable components that display content on Web pages in SharePoint 2010.

A fantastic new feature in SharePoint 2010 is that you can insert a Web Part in the text of one of the Rich Text Editor zone available in the new Wiki Page. (To add, remove, or rearrange the text zones, use the "Text Layout" menu in edit mode)
