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 ListFieldsApplication.ListFieldsWebPart
{
public partial class ListFieldsWebPartUserControl : 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) || string.IsNullOrEmpty(TextBox3.Text))
{
Label5.Text = "Please Enter Field Names";
}
else
{
CreateFields();
}
}
private void CreateFields()
{
SPSite site = SPContext.Current.Site;
SPWeb web = site.OpenWeb();
web.AllowUnsafeUpdates = true;
SPList list = web.Lists["Department"];
SPListItem item = list.Items.Add();
item.Fields.Add(TextBox1.Text, SPFieldType.Text, true);
item.Fields.Add(TextBox2.Text, SPFieldType.Text, true);
item.Fields.Add(TextBox3.Text, SPFieldType.Number, true);
item.Update();
SPView view = list.DefaultView; view.ViewFields.Add(TextBox1.Text);
view.ViewFields.Add(TextBox2.Text);
view.ViewFields.Add(TextBox3.Text);
view.Update();
Label5.Text = "The " + TextBox1.Text + ", " + TextBox2.Text + " and " + TextBox3.Text + " fields are created successfully ";
TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
TextBox3.Text = string.Empty;
}
}
}
Step 8: Deploy the solution file and add the created webpart to SharePoint site.
Step 9: The output of the application looks like this:
Step 10: When nothing has been entered, the output of the application looks like this:
Step 11: After entering column names, the application looks like this:
