ASP.NET Fileupload control enable/disable programmatically

By
Enable property defines the working mode of asp.net file upload control. It has two boolean value first one is true and second one is false. If you set true for this then control work properly otherwise control doesn't work, I mean to say that fileupload appear on screen but will not work as input control. If you want to set this property during compile time, must add attribute inside the tag. Like

  <asp:FileUpload ID="FileUpload1" runat="server" Enabled="False" />

    true is the default value for this. Now take a simple example to change the value at run time.

Source code


 <form id="form1" runat="server">  
  <div>  
     <asp:FileUpload ID="FileUpload1" runat="server" Enabled="False" />  
     <br />  
     <br />  
     <asp:Button ID="Button1" runat="server" Text="Enable/Disable" OnClick="Button1_Click" />  
     <br />  
     <br />  
     <asp:Label ID="Label1" runat="server" Text=""></asp:Label>  
   </div>  
   </form>

Code Behind 


 <script runat="server">  
   protected void Button1_Click(object sender, EventArgs e)  
   {  
     if (FileUpload1.Enabled == true)  
     {  
Label1.Text = "file upload control is enabled "; 


     
       FileUpload1.Enabled =  false;  
     }  
     else  
     {  
            Label1.Text = "file upload control is disabled ";

       FileUpload1.Enabled = true;  
     }  
   }  
 </script>

Code Generate the following output

Fileupload control disable programmatically in ASP.NET

Fileupload control enable programmatically in ASP.NET
When we press the browse button then we know that it is working or not. Above mentioned snap define this. In first, snap you can see that open file dialog doesn't appear but in second snap its appear, so in second, snap it is working.

Polynomial representation using Linked List for Data Structure in 'C'

By
Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also

Print the asp.net webpage using button

Introduction Today i am talking about printing, and how to print the content or you can say selected content in asp.net. If you have a webpage and you want to print this then you have to choose command key (ctrl+p) for that.
