Modal popup in tabs

Hi Im trying to use a modal popup in my project.

Im generating a bunch of control on my form and some of them (buttons) when clicked should open a modalpopup and on okclick store some info in a db

the problem Im having is that when I am not in the tab with the button that will make the popup open, I see the popup, but when im inside the right tab popup disapear and I can't seem to make it appear.

second problem Im having is that I can't seem to find a way for having multiple button to open the same popup.

hmm Now the modal popup is always shown. maybe its a properpy of the target control or of the popup?
Here is the code

<ajaxToolkit:ModalPopupExtenderID="MPE"runat="server"

BackgroundCssClass="modalBackground"

TargetControlID="test"

PopupControlID="PanelAddLine"

DropShadow="true"

OkControlID="SavePrice"

CancelControlID="CancelButton"

>

</ajaxToolkit:ModalPopupExtender>

<asp:PanelID="PanelAddLine"runat="server"CssClass="modal">

Enter the number of Days<br/>

<asp:TextBoxID="TextBoxNbDays"runat="server"></asp:TextBox><br/>

<asp:ButtonID="SavePrice"runat="server"OnClick="SavePrice_Click"Text="Add"OnClientClick="AfterAdd()"/>

</asp:Panel>

<asp:HiddenFieldrunat="server"ID="test"Value="a"Visible="false"/>

well im not sure about the tabbing problem because im to busy right now to try to replicate it myselft, but i think i know whats going on with the problem you have trying to open the same modal popup from different buttons. The targetControlID for a modal popup lets you set a button to open the popup, but because you want more then one button to you should do the following
* Create a hidden field and assign its ID as the targetControlID for the modal popup
* Now for each button you have that you want to open the modalPopup, create an eventhandler for the button with this code inside(example further down)

modalPopup1.Show();

* to programmatically add the event for the button do this

myButton.Click += new EventHandler(this.myButton_Click);

* and then write the click function that will be called due to the above code

private void myButton_Click(object sender, EventArgs e)
{
modalPopup1.Show();
}

thats weird, i guess i cant be much more help, i love doing stuff programatically in C# to im not great with the aspx file sytax when stuff like this happens :(

could it be just a question of css?

Do I have to set special value to my css to make the modal popup work.

Can a master page could possibly be reason for this

I think you need to call MPE.Hide(); in the server side click event handler of the save button.

Also, don't specify OkControlID="SavePrice"
