I use Timer1 to refresh few parts of masterpage but the timer refresh all page, and i need to refresh only specific parts of masterpage.

I'm no expert in this area but I'm somewhat familiar with it. Call an AJAX method for the specific portion(s) of the master page maybe? Or put it in an UpdatePanel?

I solved by removing other controls from updatepanels, i have put controls inside updatepanel only that controls which must be refreshed, other controls i removed from updatepanels. Now works great.

Thanks for assistance.

So on the users page the user can use a drop down to select their name and then click 'view' to view the list of holidays they have previously booked. From here they can choose 'select new' which will allow the user to create a new holiday. This all works fine however I want the username to be stored from the original drop down and displayed in the creating page. Instead of having 2 seperate drop downs on each page.

I have tried:

My first drop down in my Index.chtml

HTML

@Html.DropDownListFor(model => model.HList4DD.First().HolidayDate, new SelectList(Model.PList4DD, "Id", "Name", Model.currentPersonID), "--select--")

My second drop Down on the create view:

@Html.DropDownListFor(model => model.PersonId, new SelectList(ViewBag.Id, "Value", "Text"),"---Select---")

-----------------------

I wanted to change this to the name of the user previously selected so in my get of the Index I have used:

HTML

TempData["CurrentPersonID"] =currentPersonID;

Then to replace my second drop down im trying something like:

HTML

@TempData["CurrentPersonID"]

<div>
@Html.LabelFor(model => model.currentPersonID, "currentPersonID")
@Html.ValidationMessageFor(model => model.PersonId) 
</div>

Any suggestions? Thanks

Can only book for yourself and not other users?

At the min, any user can book a holiday for ay employee,

I have added [Authorization] to the controllers, and @if (User.Identity.IsAuthenticated)

in the layout so only logged in users can view the pages. But how can I go about only allowing users to book a holiday for them selves

something like if loggedInUserID(is this assigned automatically when a user is created?) =currentPersoID, although this is only a guess and I would prob have to assign the same loggedInUserID to personID.

any suggestions?

Thanks

No doubt each employee has a username/name so you can use use compare the username/name of the logged in user to the username/name of the person for whom the holiday booking id for.

Hi,
I get error while using this code ?

XML

<asp:TemplateField>
                                   <ItemTemplate >
                                       <asp:ImageButton ID="ImageDeleteBuyingKala" ImageUrl="~/ServerFile/ApplicationFiles/Icons/Button/add.png"
                                          Width="25" runat="server" OnClientClick="Open('<%# Eval("Id") %>')" />
                                   </ItemTemplate>
                               </asp:TemplateField>

I have Solved this via :

XML

<script type="text/javascript">
       function Open(IdItem) {
           // to handle in IE 7.0
           if (window.showModalDialog) {
               window.showModalDialog(location.protocol + "//" + location.host + "/" + "WorkFlows/Forms/BuyingKala/Estelam.aspx?Id=" + IdItem, "Show Popup Window", "dialogHeight:450px,dialogWidth:80%,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,modal=yes,center:yes");
           }
           // to handle in Firefox
           else {
               window.open(location.protocol + "//" + location.host + "/" + "WorkFlows/Forms/BuyingKala/Estelam.aspx?Id=" + IdItem, "Show Popup Window", "height=450px,width=80%,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,modal=yes,center:yes");

           }
          // window.showModalDialog(location.protocol + "//" + location.host + "/" + "WorkFlows/Forms/BuyingKala/Estelam.aspx?Id=" + IdItem, null, "height=290px,width=400px,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,modal=yes")
       }
   </script>

XML

<ItemTemplate>
                                        <asp:ImageButton ID="ImageEstelamBuyingKala" ImageUrl="~/ServerFile/ApplicationFiles/Icons/Button/add.png"
                                            Width="25" runat="server" OnClientClick='<%# " Open("+ DataBinder.Eval(Container.DataItem,"Id") + ");" %>' />
                                    </ItemTemplate>

Hi friends. is it possible to use an asp web site like a telephone. i ve made a website. there are 10 users of this website. ı can understand who is online and who isnt. is it possible to put a button whose text is "talk to this user" next to each user and send and play this sound stream at remote side. I found this Sending and playing microphone audio over network[^] but it is quite complicated to me. Do you have an easier idea.

Do you want the site to actually make phone calls to the users or do you want to just play the audio to them on their speakers?

phone calls via their microphones. I couldn't find an exact solution yet but i am thinking of this:

When a user clicks on a button to talk to someone else, i am planning to create a rtp stream. this stream wont go to anybody's computer. It will go to server itself but with some unique number on it. Somehow i will try to make users decode this stream using those unique numbers.

I haven't done that before. I have done phone calls, and products like Microsoft Speech Server make it pretty easy.

indeed the dropdownlist working so fine and the selected item remains even after reading selected value but IN ONLY ONE COND. that such username has a unique password

for example:

user pass
aaa 1234
bbb 1234
ccc 34343
dddd 67657

if i choose ccc it will return 34343 selected index 2
if i choose dddd it will return 67657 selected index 3
if i choose aaa it will return 1234 if aaa is higher rank than bbb
if i choose bbb it will return 1234 selected index 1

please kindly help me
