backcolor="Black" onclick="Button1_Click" width="176px" />

</td>

</tr>

<tr>

</table>

</div>

</center>

Step 5: The complete code of visualwebpart1usercontrol.ascx.cs looks like this:

using Microsoft.SharePoint;

using System;

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;namespace DeleteGroupApp.VisualWebPart1

{

[ToolboxItemAttribute(false)]

public partial class VisualWebPart1 : WebPart

{

// Uncomment the following SecurityPermission attribute only when doing Performance Profiling using

// the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready

// for production. Because the SecurityPermission attribute bypasses the security check for callers of

// your constructor, it's not recommended for production purposes.

// [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]

public VisualWebPart1()

{

}

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

InitializeControl();

}

protected void Page_Load(object sender, EventArgs e)

{

TextBox1.Focus();

}

protected void Button1_Click(object sender, EventArgs e)

{

if (string.IsNullOrEmpty(TextBox1.Text))

{

Label4.Text = "Please Enter Some Values";

Label4.ForeColor = System.Drawing.Color.Red;

}

else

{

SPWeb web = SPContext.Current.Web;

web.SiteGroups.Remove(TextBox1.Text);

web.Update();Label4.Text = TextBox1.Text + " - Group Deleted Successfully";

Label4.ForeColor = System.Drawing.Color.Green;

TextBox1.Text = string.Empty;

}

}

}

}
