c# - Selected Index Change Calling when Filling values in Combobox -

in below code have combobox. when try fill values in combobox, on loading calling selectedindexchanged without selecting value combobox.

public void bindcombobox() {         software pd = new software();     dataset dsproj = pd.userid();     cbvalue.datasource = dsproj.tables[0];//calling selectedindexchanged     cbvalue.displaymember = "projectname";     cbvalue.valuemember = "projectid"; }  private void cbvalue_selectedindexchanged(object sender, eventargs e) { } 

i guess must use boolean variable. may , used method avoid problem given below.

1) declare boolean valiable global scope, set false. 2) before binding combobox set boolean=false, , after binding has been completed set boolean=true. 2) on first line of combobox_selectionchangeevent , check condition boolean true or false. if true rest of things.

like this..

boolean flag=false  public void bindcombobox() {     software pd = new software();     dataset dsproj = pd.userid();     flag=false;     cbvalue.datasource = dsproj.tables[0];//calling selectedindexchange     cbvalue.displaymember = "projectname";     cbvalue.valuemember = "projectid";     flag=true; }  private void cbvalue_selectedindexchanged(object sender, eventargs e) {     if(flag==true)     {         ... //rest of code     } }
