dropdownlist

Question

when select a value from dropdownlist ,other dropdownlist should be disabled check my code

protected void ddl_deptname_SelectedIndexChanged(object sender, EventArgs e)
    {

        if (ddl_deptname.SelectedIndex!= (Convert.ToInt32("ORR-ORR") && (Convert.ToInt32("ORR-TOWNSHIP"))))
               { 
            ddl_orr.Enabled=false;
            ddl_township.Enabled=false;
            }
       if(ddl_deptname.Text=Convert.ToInt32("ORR-ORR"))
                ddl_township.Enabled=false;
         else
             ddl_orr.Enabled=false;
        
              
    }

so here,deptname values are orr-orr and orr-township.

when user selects orr-orr,orr-orr dropdownlist should be disabled.

error is coming.

&& operator cannot convert int to string

just give an idea for that.

thanks&regards

Answer 1

Just Seperate the two conditions:

if (ddl_deptname.SelectedIndex!= (Convert.ToInt32("ORR-ORR")) && ddl_deptname.SelectedIndex!=(Convert.ToInt32("ORR-TOWNSHIP")))

Answer 2

Can you see this?

-->  ddl_deptname.Text=Convert.ToInt32("ORR-ORR")

First of all

Convert.ToInt32("ORR-ORR") ==> Should give an FormatException. [i.e. Incorrect format of the input string].

2nd thing...

Compiler cannot implicitly convert your integer number by 'Convert.ToInt32' to a 'String'.
