Bind data to the grid at the client side using AJAX call to web service

With the Current AJAX Tool kit is there a way to databound the grid at the client side.

 Basically I want to make a WCF web service all and get the JSON message and populate the grid at the cient side. I am using Visual studio 2005 with .NET frame work 3.0. Please point out if tehre are any examples. I truly appreciate any help regarding this. Thanks

Thanks for the reply. This article is to populate the fields in the moder popup using AJAX and Javascrip. But not populating the grid itself using AJAX, webservice and Javascript.

 This sample poulates the grid on serverside in a normal way.

I am looking for a sample that can poulate the grid in cleint side.

Hi Nagu,

I think ameenkpn has provided the solution.  First , you call WebService to get a Jason object which contains all the elements of the GridView(Table).  Then, you generate the TableRows based on the Jason object. Here is the generated HTML.

<table cellspacing="0" rules="all" border="1" id="GridView1" style="border-collapse:collapse;">
  <tr>
   <th scope="col">EmployeeID</th><th scope="col">LastName</th><th scope="col">FirstName</th><th scope="col">Title</th><th scope="col">&nbsp;</th><th scope="col">&nbsp;</th>
  </tr><tr>
   <td>1</td><td>Davolio</td><td>Nancy</td><td>Sales Representative</td><td>
                        <input name="GridView1$ctl02$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl02$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl02_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$0')" mce_href="javascript:__doPostBack('GridView1','Edit$0')">Edit</a></td>
  </tr><tr>
   <td>2</td><td>Fuller</td><td>Andrew</td><td>Vice President, Sales</td><td>
                        <input name="GridView1$ctl03$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl03$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl03_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$1')" mce_href="javascript:__doPostBack('GridView1','Edit$1')">Edit</a></td>
  </tr><tr>
   <td>3</td><td>Leverling</td><td>Janet</td><td>Sales Representative</td><td>
                        <input name="GridView1$ctl04$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl04$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl04_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$2')" mce_href="javascript:__doPostBack('GridView1','Edit$2')">Edit</a></td>
  </tr><tr>
   <td>4</td><td>Peacock</td><td>Margaret</td><td>Sales Representative</td><td>
                        <input name="GridView1$ctl05$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl05$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl05_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$3')" mce_href="javascript:__doPostBack('GridView1','Edit$3')">Edit</a></td>
  </tr><tr>
   <td>5</td><td>Buchanan</td><td>Steven</td><td>Sales Manager</td><td>
                        <input name="GridView1$ctl06$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl06$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl06_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$4')" mce_href="javascript:__doPostBack('GridView1','Edit$4')">Edit</a></td>
  </tr><tr>
   <td>6</td><td>Suyama</td><td>Michael</td><td>Sales Representative</td><td>
                        <input name="GridView1$ctl07$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl07$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl07_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$5')" mce_href="javascript:__doPostBack('GridView1','Edit$5')">Edit</a></td>
  </tr><tr>
   <td>7</td><td>King</td><td>Robert</td><td>Sales Representative</td><td>
                        <input name="GridView1$ctl08$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl08$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl08_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$6')" mce_href="javascript:__doPostBack('GridView1','Edit$6')">Edit</a></td>
  </tr><tr>
   <td>8</td><td>Callahan</td><td>Laura</td><td>Inside Sales Coordinator</td><td>
                        <input name="GridView1$ctl09$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl09$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl09_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$7')" mce_href="javascript:__doPostBack('GridView1','Edit$7')">Edit</a></td>
  </tr><tr>
   <td>9</td><td>Dodsworth</td><td>Anne</td><td>Sales Representative</td><td>
                        <input name="GridView1$ctl10$TextBox1" type="text" onchange="javascript:setTimeout('__doPostBack(\'GridView1$ctl10$TextBox1\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" id="GridView1_ctl10_TextBox1" />
                    </td><td><a href="javascript:__doPostBack('GridView1','Edit$8')" mce_href="javascript:__doPostBack('GridView1','Edit$8')">Edit</a></td>
  </tr>
 </table>

So you can use Javascript to generated the TableRow and TableCell.   Here is the sample to show how to create TableCell. 

                var oCell1_1 = oRow1.insertCell(0);
                oCell1_1.innerHTML = '<a onclick="setValue(\''+ptPrefix+'a\')">'+ ptPrefix +'a</a>';
                var oCell1_2 = oRow1.insertCell(1);
                oCell1_2.innerHTML = '<a onclick="setValue(\''+ptPrefix+'b\')">'+ ptPrefix +'b</a>'; 
                var oCell1_3 = oRow1.insertCell(2);
                oCell1_3.innerHTML = '<a onclick="setValue(\''+ptPrefix+'c\')">'+ ptPrefix +'c</a>';
 

I hope this help.

Best regards,

Jonathan
