  Try out below part.

  string strval = "hello";
                  int intval = 1;
                  Page.ClientScript.RegisterStartupScript(this.GetType(), "clearControls","getFileDetailsToHidden(" + "'" + strval + "'"+ "," + intval +");", true);

  Try this:

   

  Page.ClientScript.RegisterStartupScript(this.GetType(), "clearControls", "getFileDetailsToHidden('my_value');", true);

  OR

   

  Page.ClientScript.RegisterStartupScript(this.GetType(), "clearControls", "getFileDetailsToHidden('" + TextBox1.ClientID + "');", true);

  Thanks but after i passed parameter to that function i have assigned that value in a hidden variable and then i call that hidden variable from my code behind and assigned to local variable but the value is null. why?

  code behind

  --------------------

  Page.ClientScript.RegisterStartupScript(this.GetType(), "paramFN1", "getFileDetailsToHidden('" + fileIndex + "','"+FileNames+"','"+FileExtensions+"');", true);

   

  string val=Request.Form["hdnFileIndex"];
  string val1=Request.Form["hdnFileNames"];

  string val=Request.Form["hdnFileExtensions"]; 

   

  Javascript

  ---------------

  function getFileDetailsToHidden(pFileIndex,pFileNames,pFileExtensions)

  {

  document.getElementById('hdnFileIndex').value = pFileIndex; document.getElementById('hdnFileNames').value = pFileNames; document.getElementById('hdnFileExtensions').value = pFileExtensions;

  <div></div> }

  Be what u want to be...Do wat u want to do...

  Javascript

  ---------------

  function getFileDetailsToHidden(pFileIndex,pFileNames,pFileExtensions)

  {

  document.getElementById('hdnFileIndex').value = pFileIndex; document.getElementById('hdnFileNames').value = pFileNames; document.getElementById('hdnFileExtensions').value = pFileExtensions;

   

  <div></div>

  }

  Here, are you getting the values in paramaeters pFileIndex, pFileNames and pFileExtensions ?

  Hi,

  Check if hdnFileIndex's ClientID is still 'hdnFileIndex'.

  And try this code

  protected void Page_Load(object sender, EventArgs e)
          {
              string fileIndex = "This is fileIndex";
              string FileNames = "FileNames";
              string FileExtensions = "FileExtensions";
              Page.ClientScript.RegisterStartupScript(this.GetType(), "paramFN1", "getFileDetailsToHidden('" + fileIndex + "','" + FileNames + "','" + FileExtensions + "');", true);
                  
              string val = Request.Form["hdnFileIndex"];
  
              Response.Write("fileIndex's value:  " + val);
          }

   

      <script type="text/javascript">
          function getFileDetailsToHidden(pFileIndex, pFileNames, pFileExtensions) {
              document.getElementById('hdnFileIndex').value = pFileIndex;
              document.getElementById('hdnFileNames').value = pFileNames;
              document.getElementById('hdnFileExtensions').value = pFileExtensions;
          }        
      </script>
  
      <form id="form1" runat="server">
      <input id="hdnFileIndex" name="hdnFileIndex" type="text" /><input id="hdnFileNames" type="text" /><input id="hdnFileExtensions" type="text" />
      <input id="Submit1" type="submit" value="submit" />
      </form>
