This article describes how to expand and collapse rows of a GridView or Table and showing data details using Jquery and Ajax
\n<\/strong><\/p>\n

Introduction:<\/strong><\/span><\/p>\n

Now day’s , important issue with web applications is how quick a wed page is rendered\u00a0\u00a0and how it is animated or\u00a0\u00a0visualized<\/p>\n

So for quick reply from server Ajax is the solutions and for some visualizations with server side response we mostly use jquery or javascript.
\nI this article, for exp<\/p>\n

anding , collapsing and\u00a0\u00a0adding details to gridview row we are going to use AJAX to make call to server and we will visualized it using jquery.<\/p>\n

Aim<\/strong><\/span><\/p>\n

1.\u00a0Getting details of product\u00a0\u00a0by extracting details at the next to current row and before second \u00a0 \u00a0one.<\/p>\n

2.\u00a0Visualizing\u00a0\u00a0the expanding of rows.<\/p>\n

3.\u00a0No server side postback.<\/p>\n

4.\u00a0Using GridView Control to bind data and simple data binding to table using scriptlet.<\/p>\n

Using \u00a0Jquery\u00a0Code<\/strong><\/span><\/p>\n

Expanding Row :<\/strong><\/p>\n

For expanding any row, we need to create an new row\u00a0\u00a0with the serverside details\u00a0\u00a0and then we will add it to the next of current row<\/p>\n

\"Ajax<\/p>\n

\nvar trindex=0;\t\/\/trindex hold row index created by jquery\n$("tr").click(function() {\nif ($(this).find("td:first").length > 0) { \/\/check whether it is header or content row\n\/\/row index increment to assign new row id everytime\ntrindex++;\n\/\/create a row with td colspan 3 to show product description\nvar row= '><td class="currRow" colspan="3" ><\ndiv id="did"><img id="imagepath" src=""\nstyle="height: 81px; width: 104px" \/>  Description :<\nspan id="des">sd<\/span><p>Cost :<\nspan id="cost">sd<\/span><\/p><\/div><\/td><\/tr>';\n\n\/\/adding animation to row\nvar newRow = $("<tr id=tr"+ trindex + row).animate({\nheight: "140px",\nopacity: 0.25,\n}, 500);\n\/\/adding row to existing table\n$(this).after(newRow);\n<\/pre>\n
Collapsing\u00a0 Row :<\/h5>\n
At the same moment we expand any row, we collapse previous created row, so we need to remember the previous created rowIndex or it’s id.<\/p>\n
\"Ajax<\/a>
\n<\/a><\/p>\n
\n$("#"+rowName).find('td').removeClass('currRow').addClass('hideRow');\n$("#"+rowName).animate({\n    height: "0px",\n    opacity: 0.25,\n    }, 1000, function() {\n$("#"+rowName).remove();<\/pre>\n<h5>Ajax Call to the server :<\/h5>\nFor getting the full details about our shortly highlighted product, we need to make a asynchronous call to\nserver using AJAX. We are passing some key values to server(product Id) to extract the resultset.\n<pre>$.ajax({\n       type: "POST",\n       url: "WebService.asmx\/GetDetails",   \/\/webserviceName\/methodName\n       data: "{'name': '" + $(this).find("td span").text() + "'}",  \/\/passing values to webservice(productid)\n       contentType: "application\/json; charset=utf-8",\n       dataType: "json",\n       success: function(msg) {\n       \/\/extrating response data to newly created row\n       $("#tr"+trindex ).find("td #did p #cost").text(msg.d.id );\n       $("#tr"+trindex ).find("td #did  #des").text(msg.d.order);\n       $("#tr"+trindex ).find("td #did #imagepath").attr('src', msg.d.order);\n\/\/$("#myImage").attr("src", "path\/to\/newImage.jpg");\n       },\n       error: FailedMessage     \/\/showing error message if failure\n       });\n<\/pre>\n
Using The WebService.cs<\/h5>\n
Programmable application logic accessible via standard Web protocols.We are using webservice to extract data from database using jquery Ajax call.\u00a0\u00a0CollectData class to hold extracted details from db.<\/p>\n
\npublic class CollectData\n{\n        public string cost { get; set; }\n        public string imagePath { get; set; }\n        public string description { get; set; }\n}\n<\/pre>\n
Simple queries to the database via WebMethod<\/p>\n
\n[WebMethod()]\n    public CollectData GetDetails(string name)\n    {\n        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].\n        ConnectionString);\n        SqlCommand cmd = new SqlCommand("Select cost, imagePath, description from Products where ProductId='" +\n        name + "'",con);\n        SqlDataReader data;\n        CollectData c = new CollectData();\n        try\n        {\n            con.Open();\n            data=cmd.ExecuteReader();\n            if (data.Read())\n            {\n                c.cost= data[0].ToString();\n                c.imagePath = data[1].ToString();\n                c.description = data[2].ToString();\n                return c;\n            }\n            else\n            {\n                c.cost = "N\/A";\n                c.imagePath = "N\/A";\n                c.description = "N\/A";\n                return c;\n            }\n        }\n        catch (Exception ex)\n        {\n            c.cost = "N\/A";\n            c.imagePath = "N\/A";\n            c.description = "N\/A";\n            return c;\n        }\n\n    }\n<\/pre>\n
Conclusion :<\/strong><\/p>\n
We have mixed up Jquery, Ajax, server Control(Gridview ) to get quick and visualized output. Result can be little bit change as per the browsers.<\/p>\n
