c# - ComboBox SelectedValue Returning an Object And Not The Value -

goal: when form loads doing database phone call returning me datatable want assign keyvaluepair(string,string) datasource combo-box. display fellow member beingness key (railcarid) , value fellow member beingness value (railcartransaction_guid)(i storing string).

the problem having, when combobox.selectedvalue...it returning me object rather string. can suggest doing wrong here?

i using dictionary (and error out), , thru searching resolve issue ended using bindinglist. combobox on application displays object array in display. below, code snippets:

private void getalltransactions() { bindinglist<keyvaluepair<string, string>> transactions = new bindinglist<keyvaluepair<string, string>>(); string sql = "select * railcartransaction iscomplete = 'true' , isuploaded = 'false'"; datatable transactions = session1.getrecords(sql); (int = 0; < transactions.rows.count; i++) { transactions.add(new keyvaluepair<string, string>(transactions.rows[i]["railcarid"].tostring(), transactions.rows[i]["railcartransaction_guid"].tostring())); } cboxrailcars.displaymember = "key"; cboxrailcars.valuemember = "value"; cboxrailcars.datasource = transactions; }

since combobox.valuemember set property of any info type (it int or datetime example, not string), selectedvalue property object.

you have know type you're dealing , convert back:

var selectedrailcar = convert.tostring(cboxrailcars.selectedvalue);
