          ViewData["Emp"] = GetPageBaseObject;<br />
          ViewData["ee"] = em.ToList();<br />
          return View();<br />
        <br />
       }

Here GetpageBaseObject is the List

Now Here is my View Part Code

<script  runat="server"><br />
        protected void Page_Load(object sender, EventArgs e)<br />
        {  <br />
            ddl.DataSource = ViewData["Emp"];<br />
            ddl.DataBind();<br />

Solution 1

Please try below mentioned simple way.

<input type="text" name="EMP_NAME" value="<%: ViewData["ee"].ToString()%>">

UPDATE

With your query if it's returning only one result, why you use ToLits() with it.Please try is as below for the Text box.

C#

var em =from p in GetPageBaseObject where p.EMP_ID==id select p;

ViewData["ee"] = em.FirstOrDefault().EMP_NAME;

Are you talking about the text box or the list ? What is the error ?

Sampath Lokuge 8-Feb-14 2:47am

I have updated my solution also.Please check that.

Member 10435696 8-Feb-14 2:49am

plz help me out..If i assign textbox this way in mvc
<%: Html.TextBoxFor(m => m.EMP_NAME, ViewData["ee"])%>

Then if i want to use id of textbox anywhere on viewpage...how can i do that..What is the id of textbox of above line?

Sampath Lokuge 8-Feb-14 2:52am

You can check it by using chrome dev Tool.Just select above text box and then find the relevant id of that by using 'inspect element' on chrome dev tool.

Member 10435696 8-Feb-14 2:51am

actually on page load event doesnt support <input type...> n all control..

its the problem ..otherwise my viewdata is getting the whole data from controller

What is the issue when you apply html.helper ,method with text box ?

Member 10435696 8-Feb-14 3:06am

I have used your code and it is giving this line in textbox

System.Collections.Generic.List`1[MvcApplication2.Models.Employee]

Member 10435696 8-Feb-14 3:07am

public ActionResult ShowUpdateView(int id)
{
var em =from p in GetPageBaseObject where p.EMP_ID==id select p;
ViewData["Emp"] = GetPageBaseObject;
ViewData["ee"] = em.ToList();
return View();
}

This is how i am using viewdata

Sampath Lokuge 8-Feb-14 3:22am

When you run the code is this query give single value or list 'var em =from p in GetPageBaseObject where p.EMP_ID==id select p;' ?

Member 10435696 8-Feb-14 4:24am

Yes it give only 1 record EMP_ID 1
EMP_NAME XYZ

Can u post a simple eg of saving data through json...I am jst posting an rough layout

<script type="text/javascript">
$(document).ready(function () {

alert("yy");
$("#save").click(function () {
var json = "{'USER_NAME':'" + escape(USER_NAME.val()) + "','MOBILE_NO':'" + escape(MOBILE_NO.val()) + "'}";
alert(json);
alert("RRR");
var ajaxPage = "~/User/Index/{0}";
alert(ajaxPage);
$.ajax(
{
type: "POST",
url: ajaxPage,
data: json,
contentType: "application/json;charset=utf-8",
dataType: "json",
async: false,
success: function (data) {
if (data.Message == "Data Deleted Succeffully") {
showMessage(data.Message);
$('#table').dataTable().fnAddData();
filltable();

}
else {
showMessage(data.Message);
}
},
error: function (msg) { alert("failed: " + msg); }
});

})
});

</script>

And in the controller

[HttpPost]
public ActionResult Index(User model)
{
if (ModelState.IsValid)
{
System.IO.StreamReader sr = new System.IO.StreamReader(Request.InputStream);
string line = "";
line = sr.ReadToEnd();
JObject jo = JObject.Parse(line);

var email = model.EMAIL_ID;

return View();

// return Redirect("/Book/Employee");
}
else
{
return View();
}
}
}

Can anybody post this type of eg
