Window.location.href Not Working In Safari When Using Onkeypress?
May 6, 2010I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox. Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code:
function submitSearchOnEnter(e) {

Apr 27, 2010In vsw2005/ASP.Net 2 i have a formview used for project management; i recently added a new set of dates and a dropdownlist for the contact name. It is essentially a duplicate of another set of dates and contact. Both dropdownlists use the same sqldatasource, but the new one is throwing an error when the form changes to edit mode:
"'ddlInstall2Engineer' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"
The error occurs even though I have a static listitem with appenddatabounditems set to true. Here is the markup for both ddl and sqldatasource (as you can see, other than id and name of field being bound to, they are identical):
<asp:DropDownList ID="ddlInstallEngineer" runat="server" AppendDataBoundItems="true"
