从C＃asp.net中的数据库设置复选框值

Question

I have 8 checkboxes .
On the page load event I want to write the code such that
if the value in the database is "Submitted" the checkbox will appear checked .
If the value is "Not Submitted" it will appear unchecked .

Answer 1

you can have something like this

if(!Page.IsPostBack)
{
     var isChecked = dbvalue.ToLower() == "submitted" ? true : false;
     for (var i = 0; i < 8;i++ )
     {
         CheckBox chk = (CheckBox)Form.FindControl("chk" + i);
         if(chk != null) chk.checked = isChecked;
     }
}

You can check the values like this

if(!Page.IsPostBack)
{
    if(dbvalue=="Submitted")
    {
      chk1.checked=true;
      chk2.checked=true;
      chk3.checked=true;
      chk4.checked=true;
      chk5.checked=true;
      chk6.checked=true;
      chk7.checked=true;
      chk8.checked=true;
    }
    else if(dbvalue=="Not Submitted")
    {
        chk1.checked=false;
      chk2.checked=false;
      chk3.checked=false;
      chk4.checked=false;
      chk5.checked=false;
      chk6.checked=false;
      chk7.checked=false;
      chk8.checked=false;
    }

}

If don't want to do anything in the code-behind, a faster and easy method would be to create a new column of data type bit on the select query and then just bind the checkbox to that. 0 = false and 1 = true. Example would be:

SELECT
CAST((CASE WHEN SubmitColumn = 'Submitted' THEN
    1
ELSE
    0
END) AS BIT) AS chkValue
