What is visual Webpart?

A Visual Webpart is one of the good features in SharePoint whereby it allows the user to do a drag & drop from VS 2010. Internally what happens is that in the Webpart's CreateChildControls() method it is adding the user control from the specified location. And the user control is supporting the drag & drop feature.
 
How to use a Visual Webpart?

Step 1 : Create a new Visual Web Part Project.



Step 2:



Step 3:

Farm Solution:

FARM solutions are hosted in the IIS worker processer and the code will affect the entire FARM.

Sandboxed Solution:

Sandboxed solutions are hosted in SPUCWorkerProcess and the code will affect the site collection of the solution. Visual Webparts can't be sandboxed.
 
From the Solution Explorer, open the VisulaWebPart1usercontrol.ascx page and go to Design view.

Drag the DataGridView into the Designer.



Step 4: On the Page Load event of the user control, please add the following code.

This code is used to get the available list & libraries from http://localhost site.

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                using (SPSite site = new SPSite("http://localhost"))
                {
                    using (SPWeb web = site.OpenWeb())
                    {
                        DataTable listDataTable = new DataTable();
                        listDataTable.Columns.Add(new DataColumn("ListName"));
                        listDataTable.Columns.Add(new DataColumn("Description"));
                        foreach (SPList list in web.Lists)
                        {
                            DataRow listDataRow = listDataTable.NewRow();
                            listDataRow["ListName"] = list.Title;
                            listDataRow["Description"] = list.Description;
                            listDataTable.Rows.Add(listDataRow);
                            listDataTable.AcceptChanges();
                        }
                        GridView1.AutoGenerateColumns = true;
                        GridView1.DataSource = listDataTable;
                        GridView1.DataBind();
                    }
                }
            }
        }

Step 5: Build and deploy the solution. Once it is successfully deployed go to SharePoint in your browser.[ http://localhost/ ]

Step 6 : Click on Edit Page from the Site Actions menu.



Step 7 : Click on Edit Tools-> Insert->Webpart. The deployed web part will be available under the Custom Category. Click on the Custom category option; then you can get the new deployed visualwebpart1. Select the VisualWebpart1 and Click Add button.



Step 8 : Once you've added it, click on the Save & Close button.



Step 9 : Output of the Visualwebpart1.
