Question

i am using text box to update User record, it Submits half name to database e.g. if Name is 'John Mathew' then it only submits 'John'. EVen i checked in deugging that value being sent from Textbox to action is complete but submitted half, why ? i noticed, my textbox is binded to EmplName field in database and it picks half name from there, in value it shows half name that's why it submit half name why ?
this line :
Controller:
public ActionResult InsertEmployeeEditedDetail(String EmpName, String DeptID, String ShiftId, String EntryDate, String Salary, String Email, bool Approval)
{
int? EmplId = Convert.ToInt32(Session["EmpEdit"]);
var UpdateRec = DataContext.UpdateEmployeeDetails_Sp(EmplId, EmpName, DeptID, ShiftId, EntryDate, Salary, Email, Approval);
return View();
}
View:
#using EmployeeAttendance_app.Models
#model IEnumerable<GetEmployeeEditDetails_SpResult>
#{
var Item = Model.FirstOrDefault();
}
<style type="text/css">
</style>
<div>
#using (Html.BeginForm("InsertEmployeeEditedDetail", "Home", FormMethod.Post))
{
<label id="lblName" class="editEmp_label">Name</label>
<input type="text" value= #Item.EmplName name="EmpName" placeholder="Update Name" />
<br />
<label id="lblDept" class="editEmp_label">Department</label>
#Html.DropDownList("DeptID", #Item.DeptName)
<br />
<label id="lblShift" class="editEmp_label">Shift</label>
#Html.DropDownList("ShiftId", #Item.ShiftName)
<br />
<label id="lblEntryDate" class="TxtBoxFrom editEmp_label">Entry Date</label>
<input type="text" value= #Item.EntryDate class="TxtBoxTo" name="EntryDate" placeholder="Update Date" />

<input type="text" value= #Item.BasicSalary name="Salary" placeholder="Update Salary" />

<input type="text" value= #Item.EmailAdd name="Email" placeholder="Update Email" />
<br />
<label id="lblApproved" class="editEmp_label">Overtime Approval</label>

Answer 1

enclose value attribute value in double quots value="#Item.EmplName". If there is space in the name, Last name (after space) becomes attribute to the input control which is not visible and can't be sent back.

Answer 2

it would be better if you use #Html.TextBoxFor(),this would handle binding as well instead of explicitely setting the textbox value using 'value'

Answer 3

Given that all your code looks reasonable enough, I can only think of a few possibilities:
Perhaps the code that calls your stored procedure from the DataContext has the parameter length for EmplName as something much shorter.
Perhaps the database table has a trigger that is manipulating that column's value.
Perhaps something is going wrong - like an output parameter that is too short - when you retrieve the data from the database and display it.
