Below is my javascript code which clears the label message not a vaild document while choosing the file using fileuploader but the problem is it works fine in hiding the label message till it is not uploaded successfully but once if the file is uploaded again if i upload the fle by giving wrong month and year i need to show not a valid document but it is not displaying anything

<asp:FileUpload ID="FileUpload1" runat="server"  onchange="callme();" />

function callme() {
         document.getElementById("your message label id").value= "";
       }

c# code

if (month == ddlmonth.SelectedValue && year == ddlyear.SelectedValue)
               {
                   Ismatch = true;
                   //break;
               }
               else
               {
                   Ismatch = false;
                   break;
               }
           }
           if (Ismatch == true)
           {
               lblerrorMessage.Visible = false;
               lblerrorMessage.Text = "Valid Document";
           }
           else
           {
               lblerrorMessage.Text = "Not a Valid Document";
               ddlmonth.ClearSelection();
               ddlyear.ClearSelection();
               label1.Text = "";
               return;
           }

What I have tried:

I tried it but its not working because it hides the message not a valid document once it is uplaoaded successfully

Solution 1

Use

<input type="hidden" name="lblerrorMessage" id="lblerrorMessage" runat="server" value=""  />

I think Onchange

callme();

method should be remove. Its should be call from after Upload sucessfully

if (Ismatch == true)
           {
               lblerrorMessage.Value = "Valid Document";
               ClientScript.RegisterStartupScript(GetType(), "Javascript", "javascript:callme();", true);

           }
           else
           {
               lblerrorMessage.Value = "Not a Valid Document";
               ClientScript.RegisterStartupScript(GetType(), "Javascript", "javascript:callme(); ", true);
               return;
           }
