The web part consists of following elements:

  1. a TextBox for Specifying the folder Name.
  2. asp:FileUpload to fetch the file to be uploaded.
  3. an asp:Button named Upload to upload the file. all the code needs to be written in its _click() event.

The web part has following elements


<table> <tr> <td>Enter the Name of Document Library:- </td> <td title="Enter the Name of Document Library if left blank then Default Document Liberary"> <asp:TextBox ID="txtLibraryName" runat="server"></asp:TextBox> </td> </tr> <tr> <td>Enter the Date of Document:- </td> <td title="Enter the Date of Document if left blank then random Date"> <asp:TextBox ID="txtDate" runat="server"></asp:TextBox> </td> </tr> <tr> <td>Browse the File:- </td> <td title="Browse the File if not then no file will be uploaded only a folder will be created"> <asp:FileUpload ID="FileUpload" runat="server" /> </td> </tr> </table> <br /> <asp:Button ID="btnFileUpload" runat="server" Text='Upload "File" to a "Folder"' OnClick="btnFileUpload_Click" />


I have done the above program in SharePoint SSOM
`

    protected void btnFileUpload_Click(object sender, EventArgs e)

        //Web initilization
        SPSite site = new SPSite("http://spappdc:33333/sites/Access");
        SPWeb web = site.OpenWeb();
        web.AllowUnsafeUpdates = true;

        //Check Date TextBox
        CheckLibrary(web);

        web.AllowUnsafeUpdates = false;
    }

`

`

    public void CheckLibrary(SPWeb web)
    {

        //Check Library TextBox

Most Probable Answer in CSOM Similar to your SSOM Code could be
Select Date:<asp:TextBox ID="dateTxt" runat="server"></asp:TextBox><br /><br /> Add file:<asp:FileUpload ID="fileUpload" runat="server" /><br /><br /> <asp:Button ID="Savebtn" runat="server" Text="Save" OnClick="Savebtn_Click" /><br /><br /> <asp:Label ID="msgLbl" runat="server" Text=""></asp:Label>
