  problem with window.location at code behind

  Nov 19, 2012 01:03 AM|LINK

  i put a hyperlink under my gridview.

  <asp:TemplateField HeaderText="regular">
  
  <ItemTemplate>
  
  <asp:HyperLink ID="hlReset" runat="server" NavigateUrl='<%# deleteConfirm(Eval("comp_id")) %>'
  Text='Delete'> </asp:hyperLink>
  
  </asp:TemplateField>

  Code Behind:

  public string deleteConfirm(object comp_id)
  
  { 
  
     string ID = (string)comp_id;
   
     return @"javascript:var result = confirm('Are you sure you want to delete selected item?');
  
     if(result)
  
     {
  
        window.location='delete.aspx?id=' + ID;
  
     }
  
     else{
  
        return false;
  
     }";

  
  the popup message was appear, but it wont bring me to the new page after i click "Yes", i bet there is a problem with my javascript at code behind, please advice me.

  try using window.open if you want to use same logic
  i.e.

  public string deleteConfirm(object comp_id)
  
  {
  
     string ID = (string)comp_id;
   
     return @"javascript:var result = confirm('Are you sure you want to delete selected item?');
  
     if(result)
  
     {
  
        window.open('delete.aspx?id=' + ID, '_self');
  
     }
  
     else{
  
        return false;
  
     }";

  Or you can you do this without using the Code behind.
  Use this code

  <asp:TemplateField HeaderText="regular">
  
  <ItemTemplate>
  
  <a href='javascript:if confirm('Are you sure you want to delete selected item?') { windo.open('delete.aspx?id='+<%# Eval("comp_id") %>, '_self'); } else { return false; }>Delete</a>
  
  </asp:TemplateField>

  Then try my other solution, which is

  <asp:TemplateField HeaderText="regular">
  
  <ItemTemplate>
  
  <a href='javascript:if confirm('Are you sure you want to delete selected item?') { windo.open('delete.aspx?id='+<%# Eval("comp_id") %>, '_self'); } else { return false; }>Delete</a>
  
  </asp:TemplateField>

  Also I just noticed that you are using ID within string. Infact you have to concatinate in string.

  i.e. your code should be

  public string deleteConfirm(object comp_id)
  
  {
  
     string ID = (string)comp_id;
   
     return @"javascript:var result = confirm('Are you sure you want to delete selected item?');
  
     if(result)
  
     {
  
        window.location='delete.aspx?id='"+ID+"';
  
     }
  
     else{
  
        return false;
  
     }";

  i tried several ways to open the new windows, but none of it working. but if i just simple link it to another page without the confirmation box, it's working...

  so, i believe the problem is not the way we open/link to a new page.. 

  is there any way i can rewrite the javascript code without "return" in front of the ' @"javascript ' ?

  Why don't you try the Client side solution I told? It down't involved the Code behding (the return statement)

  <asp:TemplateField HeaderText="regular">
  
  <ItemTemplate>
  
  <a href='javascript:if confirm('Are you sure you want to delete selected item?') { windo.open('delete.aspx?id='+<%# Eval("comp_id") %>, '_self'); } else { return false; }>Delete</a>
  
  </asp:TemplateField>

  it's working if i do it this way:

  function del()
  {
     if(confirm('delete?')){
     window.open('delete.aspx');
  }
  else
  {
     return false;
  }
  
   <a onclick=del()>Delete</a>

  
  but if i include the Eval(as below), it's said that del does not exist in the current context...

  <a onClick='<%# del(Eval("comp_id")) %>'> delete </a>

  <a onClick='javascript:del(<%# Eval("comp_id") %>);'> delete </a>
