Step 7: The complete code of visualwebpart1usercontrol.ascx.cs looks like this:
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
namespace DocumentLibDelete.DeleteWebPart
{
public partial class DeleteWebPartUserControl : UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Focus();
}
protected void Button1_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))
{
Label4.Text = "Please Enter Name and ID to Delete";
Label4.ForeColor = System.Drawing.Color.Red;
}
else
{
SPSite site = SPContext.Current.Site;
SPWeb web = site.OpenWeb() as SPWeb;
web.AllowUnsafeUpdates = true;
SPList listdoc = web.Lists[TextBox1.Text];
SPListItem item = listdoc.GetItemById(Convert.ToInt32(TextBox2.Text));
listdoc.OnQuickLaunch = true;
item.Delete();
web.AllowUnsafeUpdates = false; web.Dispose();
web.Dispose();
Label4.ForeColor = System.Drawing.Color.Green;
Label4.Text = TextBox2.Text + "'item in " + TextBox1.Text + " Document Library is deleted successfully";
TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
}
}
}
}
