catch (Exception ex)             
{               
}             
return View(configuration);
}

View

@if (ViewBag.Action == "Edit")

@Html.DropDownList("Conf_Type", ViewBag.Conf_Type as SelectList, new { selected = @Model.Conf_TypeName, @class = "form-control" })

else

@Html.DropDownList("Conf_Type", ViewBag.Conf_Type as SelectList, "Select Type", new { required = "required", validationmessage = "Please select Type", selected = @Model.Conf_Type, @class = "form-control" })

@Html.HiddenFor(m => m.Conf_TypeName, ViewBag.Conf_TypeName as SelectListItem)

Ya, I am got answer

View

@if (ViewBag.Action == "Edit")

@Html.DropDownList("Conf_Type", ViewBag.Conf_Type as SelectList, new { selected = @Model.Conf_TypeName, @class = "form-control" })

We need to replace this red line of code with blue line code

@Html.DropDownList("Conf_Type", null, new { @class = "form-control" })

else

@Html.DropDownList("Conf_Type", ViewBag.Conf_Type as SelectList, "Select Type", new { required = "required", validationmessage = "Please select Type", selected = @Model.Conf_Type, @class = "form-control" })

@Html.HiddenFor(m => m.Conf_TypeName, ViewBag.Conf_TypeName as SelectListItem)

Thanks every one for support

Now i need to get the selected value of dropdown in edit view page(at now it is showing by default first value like we have values server,mouse monitor, keyboard, pehripeheral device etc now at the the time of creation of Asset, I have select the value keyboard from dropdown for that page , as I go for editing of that Asset page, this page of dropdown should not populate the previous selected value of dropdown "keyboard" it is showing first value of dropdown "Server" I want previous selected value of dropdown "Keyboard") do some manipulation. But not getting the idea. Code which i have tried. as I have attached the screen shot in Images.rar file, please check.
