In this case, it looks like your dropdownlist is doing a partial postback within updatepanel4 but Panel1 is not in an updatepanel so it can't be updated in a partial postback. Either remove all the updatePanels or place Panel1 in an update panel.

You need to place your panel inside the update panel for it to work. Controls outside update panel cannot work for events of controls inside the update panel.

How to allow user to search without refreshing the page

I have the following three dropdownlist and a button which gives a result based on the selected criterias:
<asp:DropDownList ID="slcLocation" runat="server" ClientIDMode="Static">
</asp:DropDownList>
<br />
<br /><br />
<asp:DropDownList ID="slcSpecialty" runat="server" ClientIDMode="Static">
</asp:DropDownList>
<br /><br />
<asp:DropDownList ID="slcGender" runat="server" ClientIDMode="Static">
<asp:ListItem Text="Any Gender" Value="" Selected="True" />
<asp:ListItem Text="Male" Value="1" />
<asp:ListItem Text="Female" Value="2" />
</asp:DropDownList>
<asp:Button ID="btnGoAll" Text="Search All" OnClick="btnGoAll_Click" runat="server" ClientIDMode="Static" />
The first two dropdownlist populates using code-behind function.
How can I allow the user to select all three options and hit the search button to display the result without refreshing the page?
I tried something like this:
<div style="width: 390px; margin: 0 auto;">
<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:DropDownList AutoPostBack="True" ID="slcLocation" runat="server" ClientIDMode="Static" style="width: 365px;" class="default" AppendDataBoundItems="true">
</asp:DropDownList>
<br /><br />
<asp:DropDownList AutoPostBack="True" ID="slcSpecialty" runat="server" ClientIDMode="Static" style="width: 365px;" class="default" AppendDataBoundItems="true">
</asp:DropDownList>
<br /><br />
<asp:DropDownList AutoPostBack="True" ID="slcGender" runat="server" ClientIDMode="Static" style="width: 365px;" class="default" AppendDataBoundItems="true">
<asp:ListItem Text="Any Gender" Value="" Selected="True" />
<asp:ListItem Text="Male" Value="1" />
<asp:ListItem Text="Female" Value="2" />
</asp:DropDownList>
</ContentTemplate>
<Triggers>

</Triggers>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="slcSpecialty" />
</Triggers>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="slcGender" />
</Triggers>
</asp:UpdatePanel>
</div>
<br /><br />
<div style="width: 390px; margin: 0 auto;">
<asp:HyperLink class="loginButton" style="padding: 10px; float: right;" runat="server" ID="aSearchSubmit" ClientIDMode="Static" OnClick="btnGoAll_Click" Text="Search" />
</div>
I update my Repeater with the data retrieved from the search:
<div style="width: 100%;">
<asp:Repeater runat="server" ID="rptContent">
<HeaderTemplate>
<table border="0" ID="tblInfo" style="background: #43A79A; width: 100%;" ClientIDMode="Static">
<tr>
<td>Physician Name</td>
<td>Image</td>
<td>Gender</td>
<td>Office1</td>
<td>Office2</td>
<td>Office3</td>
<td>Office4</td>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%# Eval("Physician Name").ToString() %></td>
<td><img src="www.site.com/<%# Eval("Image").ToString() %>" /></td>
<td><%# Eval("Gender").ToString() %></td>
<td><%# Eval("Office1").ToString() %></td>
<td><%# Eval("Office2").ToString() %></td>
<td><%# Eval("Office3").ToString() %></td>
<td><%# Eval("Office4").ToString() %></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</div>
When I click on the button, nothing happens.
How can I resolve the issue?
I think what do you want is this.
You need set how updatePanel´s trigger the button.
The part of page what do you want update need to be inside the updatepanel.
The javascript will catch DropDownList changes, and after all three DropDownList were changed the postback will be raised like if you was clicked in button

if i click the btnAdd the value inside category textbox should go to database and popup the window .... but in my project the btnADD button's click event is not firing and modalpopup is working.... please give me a solution..
I've had the same problem, for some reason when you set a button as the TargetControlID of the modal popup it disables the Click event.
The way I overcame this issue was by placing an invisible/dummy Label control on the page and setting the TargetControlID property of the modal to this Label.Then in your btnAdd Click event get all the necessary values from the db and simply call the ModalPopupExtender1.Show() to display the modal:
ASPX:
<form id="form1" runat="server">

When two modal popup, my update button cannot be click ans execute the update codes. And when i remove my create modal popup, my updates work?

You should look at utilising the ValidationGroup attribute for validators. For example for all the validators in the atpAddEmployee tab you would set the attribute like so ValidationGroup="atpAddEmployee" or any other name that you think appropriate.
I've taken one of the validators from the atpAddEmployee tab and added the attribute as described above.
<asp:RequiredFieldValidator ID="rfvCode" runat="server" ErrorMessage="*" ControlToValidate="txtACode" ValidationGroup="atpAddEmployee"></asp:RequiredFieldValidator>
For that particular tab you would also need to add the ValidationGroup attribute to the button that should trigger the validation, see below.
<asp:Button ID="btnAddEmployee" runat="server" Text="Add Employee" CssClass="btn" onclick="btnAddEmployee_Click" ValidationGroup="atpAddEmployee" />

If you want your modal popup to be displayed when the user clicks on the btn_Add_Task button, you should set that button as the TargetControlID of the extender:
<cc1:ModalPopupExtender ID="btn_Add_Task_ModalPopupExtender" runat="server"
TargetControlID="btn_Add_Task" PopupControlID="pnl_Add_Task"
BackgroundCssClass="modalBackground" DropShadow="True" />
In your current code, the modal popup is triggered by a button named Dummy_btn, which I can't find in your markup, but which probably isn't what you want.
We had many issues with ajax popup. you might want to try the approach we have been using for past one month or so with out any issues. This approach creates a popup with out need of ajax / jquery / javascript /css/ update panel .
here:
A modal popup with out using ajax, update panel, jquery or javascript- surprisingly this seems to work
