It appears that a button that is used as the OK or CANCEL button for a ModalPopupExtender cannot have a click event   I tested this out by removing the   OkControlID  ModalOKButton    from the ModalPopupExtender tag  and the button click fires   I ll need to figure out another way to send the data to the server

I often use a blank label as the TargetControlID  ex   lt asp Label ID  lblghost  runat  server  Text      gt    I ve seen two things that cause the click event not fire  1  you have to remove the OKControlID  as others have mentioned   2  If you are using field validators you should add CausesValidation  false  on the button   Both scenarios behaved the same way for me

I ve found a way to validate a modalpopup without a postback   In the ModalPopupExtender I set the OnOkScript to a function e g ValidateBeforePostBack    then in the function I call Page ClientValidate for the validation group I want  do a check and if it fails  keep the modalpopup showing  If it passes  I call   doPostBack   function ValidateBeforePostBack          Page ClientValidate  MyValidationGroupName          if  Page IsValid      doPostBack                 else    find  mpeBehaviourID   show

None of the previous answers worked for me  I called the postback of the button on the OnOkScript event    lt div gt       lt cc1 ModalPopupExtender PopupControlID  Panel1            ID  ModalPopupExtender1           runat  server  TargetControlID  LinkButton1  OkControlID  Ok            OnOkScript    doPostBack  Ok       gt       lt  cc1 ModalPopupExtender gt        lt asp LinkButton ID  LinkButton1  runat  server  gt LinkButton lt  asp LinkButton gt    lt  div gt             lt asp Panel ID  Panel1  runat  server  gt       lt asp Button ID  Ok  runat  server  Text  Ok  onclick  Ok Click    gt               lt  asp Panel gt

It could also be that the button needs to have CausesValidation  false   That worked for me

I was just searching for a solution for this     it appears that you can t have OkControlID assign to a control if you want to that control fires an event  just removing this property I got everything working again   my code  working     lt asp Panel ID  pnlResetPanelsView  CssClass  modalPopup  runat  server  Style  display none   gt       lt h2 gt          Warning lt  h2 gt       lt p gt          Do you really want to reset the panels to the default view  lt  p gt       lt div style  text-align  center   gt           lt asp Button ID  btnResetPanelsViewOK  Width  60  runat  server  Text  Yes               CssClass  buttonSuperOfficeLayout  OnClick  btnResetPanelsViewOK Click    gt  amp nbsp           lt asp Button ID  btnResetPanelsViewCancel  Width  60  runat  server  Text  No  CssClass  buttonSuperOfficeLayout    gt       lt  div gt   lt  asp Panel gt   lt ajax ModalPopupExtender ID  mpeResetPanelsView  runat  server  TargetControlID  btnResetView      PopupControlID  pnlResetPanelsView  BackgroundCssClass  modalBackground  DropShadow  true      CancelControlID  btnResetPanelsViewCancel    gt
