Hi I have a dropdown which has month name as text field and int like 1,2,3 as value .
Now in database the value is stored for month.

On scr2 when Edit button is clicked ,I am getting all the values and binding to the page fields but how to bind dropdown with value field of 1?

I have used below logic to bind dropdown:

C#

System.Globalization.DateTimeFormatInfo dateTimeInfo = new System.Globalization.DateTimeFormatInfo();
            for (int i = 1; i < 13; i++)
            {
                ddlMonths.Items.Add(dateTimeInfo.GetMonthName(i).ToString());



            }

What I have tried:

i tried using

ddlMonths.selectedvalue = session[]  // ( the value from column is in session )

few queries
1) what is the database column type for month ( storing as 1,2,3 or january, feb ... )
2) in both the drop down how you are populating the values ( 1,2,3 or jan feb .. )

For binding the dates use

C#

System.Globalization.DateTimeFormatInfo dateTimeInfo = new System.Globalization.DateTimeFormatInfo();
               for (int i = 1; i < 13; i++)
               {
                   string monthName = dateTimeInfo.GetMonthName(i);
                   ddlMonths.Items.Add(new ListItem(monthName, i.ToString()));
               }

To get Selected Value

C#

int monthNumber = Convert.ToInt16( ddlMonths.SelectedValue);

Storing Selected value in session

C#

Session["MonthValue"] = ddlMonths.SelectedValue;

Assigning the Month to the Dropdown

C#

ddlMonths.SelectedValue = Session["MonthValue"].ToString();

OK i tried this but it binds the dropdown back to original months. so what I am doing is if(!ispostback)
binddropdown
if (session has value)
setting dropdown .

Is this correct ? I will try again and will update you accordingly . Thank you for help

yes you have to bind in


 protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                System.Globalization.DateTimeFormatInfo dateTimeInfo = new System.Globalization.DateTimeFormatInfo();
                for (int i = 1; i < 13; i++)
                {
                    string monthName = dateTimeInfo.GetMonthName(i);
                    ddlMonths.Items.Add(new ListItem(monthName, i.ToString()));
                }
 
            }
        }
