大家好，





这里我是MVC新手。所以如何设置TEXTBOX \DROPDOWN并从table.can绑定你简要解释我。并添加水印。

hi to all,


Here i'm new for MVC. so how to set TEXTBOX\DROPDOWN and it bind from table.can you explain me briefly.and add Water mark.

DESCRIPRION:
If i want to type a starting letters and it will filer .And one more think in dropdown oly show 5 members then we will scroll for next one ok. dont show all the members in dropdown it will limited only then we will scroll for another one ok.

推荐答案

@Html.TextBox("txtNane", "Enter Your WaterMark", new
{
    id = "txtId",
    onfocus = "if(document.getElementById('txtId').value=='Enter Your WaterMark')document.getElementById('txtId').value='';",
    onblur = "if(document.getElementById('txtId').value=='')document.getElementById('txtId').value='Enter Your WaterMark';"
})

如果您想要更多声明onfocus上的函数名称或textbox lik的onblur方法设置forcolor灰色等..你可以制作javascript函数并调用它。



用于绑定

if you want more statement in a function name on onfocus or onblur method of textbox like set forcolor gray etc.. you can make javascript function and call it.

for binding

@Html.TextBox('',Your Bind Object)(in above i have bind string 'Enter Your WaterMark'


dropdown for show only 5 record you have to take a dropdown under div tag and set height of div with autoscroll style
 
Bind Drop Down List with Datasource in my case i have  List<string>
<pre> @Html.DropDownListFor(s => s.myFriendList, new SelectList(Model.myFriendList))
