I have a sharepoint test page. I inserted my webpart earlier before my development, but after a period of time now I find that when I click "edit page", the "loading" tag will run forever and I cannot edit my page.
Then I tried to type "?Contents=1" after my page url, delete the webpart and re-add it. When I tried to save my changes, the "saving" tag also runs forever.
Such issue only happens to my webpart. I tried to use other webparts and they works perfectly. Any one got some idea?
OK,I find the reason. Since my webpart has an textbox validator and by default the textbox is hidden, when I click "edit page", the validator will be fired and prevent the editing. I put the following code in my page_load JavaScript and the issue is solved.
$(function () {
var rfv = document.getElementById("<%=rfvName.ClientID%>");
ValidatorEnable(rfv, false);
});
