I'm not sure about having understood your question, but if your goal is to select an option according with the value of a variable, this accomplishes your expectations:

XML

<select name="cmbStatus">
    <option value= 'I' @(ch == "I" ? "selected = 'selected'" : "")>impossible</option>
    <option value= 'U' @(ch == "U" ? "selected = 'selected'" : "")>unvisited</option>
    <option value= 'P' @(ch == "P" ? "selected = 'selected'" : "")>priced</option>
    <option value= 'W' @(ch == "W" ? "selected = 'selected'" : "")>in progress</option>
    <option value= 'R' @(ch == "R" ? "selected = 'selected'" : "")>ready</option>
</select>

How can I select the appropriate option programmatically based on the value of ch
Using JavaScript you can set like:

JavaScript

function setDropDownSeletedValue(selectedValue)
{
    var myCB=document.getElementById('myCB');
    myCB.value=selectedValue;
}

Now, set value from code behind or JS directly:

C#

//Get value from DB
string valueFromDB = "W";//e.g value in DB is 'Second'
string script = string.Format("setDropDownSeletedValue('{0}')", valueFromDB);
ClientScript.RegisterStartupScript(this.GetType(), "KeyValue", script, true);
