  ASP.NET Local Storage save a item of DataSet XML failture

  Dec 13, 2012 05:22 AM|LINK

  I use ASP.NET with VB. myDataSet is a DataSet with some data. I want to save the DataSet XML to Local Storage and then load the item from Local Storage offline. But now I seem to be failed to write the item of xml to Local Storage. Does somebody know how to solve this problem?

  Dim xml As String = myDataSet.GetXml()
  Dim str As String = "<script> localStorage.setItem('key1', '" & xml & "'); </script>"
   
  ScriptManager.RegisterClientScriptBlock(Me, Me.GetType(), "showmessage1", str, False)

  Hi,

  Before using HTML5 LocalStorage, it's better to check whether the browser supports it.

  http://roopeshreddy.wordpress.com/2011/12/25/localstorageavoid-cookies/

  Moreover, You can also check this thread - http://stackoverflow.com/questions/3232872/is-5mb-the-de-facto-limit-for-w3c-web-storage

  Are you using ASP.NET AJAX? I got doubt since you are calling RegisterClientScriptBlock method on ScriptManager! if you are not using, then try to call it using - Page.ClientScript.RegisterStartupScript

  Hope it helps u...

  Thanks & Regards

  Hi,

  Check this site for localStorage store limitations:

  http://dev-test.nemikor.com/web-storage/support-test/

  or alternatively use IndexedDB. (check my blog below).

  Happy Coding ! Mark as Answer if it helps.

  I had resolved this problem

      Dim xml As String = sqldsPHIS.GetXml()    

      xml = xml.Replace("" & vbCrLf & "", " ")

   

  <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="SaveLS()"/>
          <asp:Button ID="Button2" runat="server" Text="Button" OnClientClick="LoadLS()"/>
          <input type="hidden" id="hiddenbox" runat="server"/>
  
          <script>
              function SaveLS() {
                  localStorage.setItem("key1", "abc");
              }
  
              function LoadLS() {
                  var d = localStorage.getItem('key1');
                  var c = document.getElementById('FeaturedContent_hiddenbox');
                  c.value = d;
                  alert(c.value);
              }
          </script>

      Protected Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
  
          Dim b As String = hiddenbox.Value
  
      End Sub
