my codes:
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

.cs file:
protected void Page_Load(object sender, EventArgs e)
{
pnlMname.Visible = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

pnlname.Visible = true;
}
else if (DropDownList1.SelectedValue == "حقوقی")
{

pnlMname.Visible = true;

Try Like This:
Use your All code Inside Update Panels
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
// All Controls Placed Here
</ContentTemplate><Triggers>
</Triggers> </asp:UpdatePanel>
By default it will use Asynchronous postback

Button Control No Engaging After Calender Selector Is Used

I have a calender selector that looks like
<asp:ImageButton ID="calStartImage" runat="server" ImageUrl="../images/SmallCalendar.gif"
AlternateText="Please select start date" />
<ajaxToolkit:CalendarExtender ID="calStartDate" runat="server" TargetControlID="txtStartDate"
Format="MM/dd/yyyy" PopupButtonID="calStartImage" />
And A search button that look like this
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="false" />
When I select a date from the calender and press Search..The first time btnSearch_Click doesnt fire..If I click Search again it works fine. So I have to click the Search button twice before the click event works. This only happens if I select a date from the calender control.
Here is the full control:

Any Ideas?

You need to add ValidationGroup to your validation controls so that each validation group can perform validation independently from other validation group on a specific page. more you can read here Specifying Validation Groups
Here is your code with group validation. you can change it as your environment.

Hope this helps.

I don't know why but your problem can be solved by setting the CausesValidation property of btnSearch to true
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="true" />

How can I get validators to work in ASP.NET?

I'm trying to implement validation in my ASP.NET Webforms application. Right now, the only validator that works is for the Date of Birth (DOB) field. It is a custom field.

What could be the problem that's causing this code not to work, yet is not throwing any errors? Also, I'd like to position the validators better, and add color to them?

You are using a ValidationGroup for all your validators except the DOB Custom validator.
Add it to your custom validator and also the Register Button.
<asp:CustomValidator runat="server"
ID="DateRangeCustomValidator"
ControlToValidate="DOBTextBox"
onservervalidate="valDateRange_ServerValidate"
ErrorMessage="Enter a valid date. "
ValidationGroup="RegistrationWizard"/>
<asp:Button ID="RegisterButton" runat="server" Text="Register"
ValidationGroup="RegistrationWizard" onclick="registerbutton_Click"/>

You have ValidationGroup set on your validators but not on your button.

Table display issue

I got a table with 2 nested tables inside that display my two repeaters. My repeaters display Home and office addresses respectively. The problem is that whenever I add a new record in one repeater, the other repeater table's display gets messed up. Like if I add a record in rpt1 , then table for rpt1 moves up and table for rpt2 goes down..ie the headers do not display in one single line . They move up and down when records are added or deleted. WHat I want is these headers to be fixed so if I add new records or delete records, the headings of both repeaters display on the same line...How do I fix this ? Hope its not confusing.

Use css attribute valign and set its value to top like this <td width="50%" valign="top">.
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td width="50%" valign="top">
<asp:Panel ID="pnlAddAddress" runat="server">
......
</asp:Panel>
</td>
<td valign="top">
<asp:Panel ID="pnlSping" runat="server">
......
</asp:Panel>
</td>
</tr>
</table>

For headers look to use the <th> element, this will keep them at the top of the table.
Put the <table> tags you do have outside your repeater controls, make sure the repeater only renders a single row and the same for the header.
Unless you have good reason consider just wrapping the two tables in <div> tags as nested tables really don't work ideally for layout.
