Here is my aspx:
<asp:Panel ID="pnl_updateClinicVisit" runat="server" CssClass="modalPopupClinicVisitEntry2" DefaultButton="bt_editClinicVisit_submit" Style="display:none">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button AutoPostBack="false" UseSubmitBehavior="false" ID="AddMedicationChange" ClientIdMode="Static" runat="server" Text="Add Med Change" OnClick="AddMedicationChange_Click" />
<asp:Panel ID="AddNewMedicationPanel" runat="server">
<asp:TextBox ID="NewDrugName" OnTextChanged="NewDrugName_TextChanged" runat="server"></asp:TextBox>
<asp:AutoCompleteExtender ID="NewDrugNameAutoCompleteExtender"
runat="server"

<asp:ListItem>Drug -</asp:ListItem>
<asp:ListItem>Dose ↑</asp:ListItem>
<asp:ListItem>Dose ↓</asp:ListItem>
</asp:DropDownList>
<asp:Button AutoPostBack="false" UseSubmitBehavior="false" ID="SubmitMedChange" runat="server" Text="Add to Visit" OnClick="SubmitMedicationChange_Click" />
</asp:Panel>
<asp:ModalPopupExtender ID="updateClinicModalPopupExtender" runat="server" TargetControlID="bt_editClinicVisit_dummy"
PopupControlID="pnl_updateClinicVisit" CancelControlID="bt_editClinicVisit_cancel"
DropShadow="true" BackgroundCssClass="modalBackground" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
For some reason my page is reloading when I click the "AddnewMdication" and "SubmitMedChange" buttons. When I have the AutoPostBack=false UseSubmitBehavior=false, the events fire and then the page reloads. If I don't have these attributes then the page reloads before the events even fire. How do I get AJAX functionality within this modal?
Try setting your Buttons as an AsyncPostBackTrigger. You can do this by adding in the Triggers section and declaring the UpdatePanel as a conditional update.
For example
<asp:UpdatePanel ID="UpdatePanel1" runat="server"
UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="AddMedicationChange" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="SubmitMedChange" EventName="Click" />
</Triggers>
<ContentTemplate>
<%-- Your code here --%>
</ContentTemplate>
</asp:UpdatePanel>
What this should do is to explicitly declare that those two buttons as being Async.
If this doesn't work, will you please post the relevant code to your two button OnClick events? AddMedicationChange_Click and SubmitMedicationChange_Click
If you try to interact with controls outside of the UpdatePanel in your code-behind during an asyncpostback, odd things can start to happen.

I have been through several links but didn't find anything helpful. I know it has been asked several times here.
Here is my frontend code
<asp:UpdatePanel runat="server" ID="UpdatePanel1" UpdateMode="Conditional">
<ContentTemplate>
<asp:FileUpload runat="server" ID="fuItemImage" Width="370px" TabIndex="12" />
</ContentTemplate>
<Triggers>
</Triggers>
</asp:UpdatePanel>
Here is the backend code
if (fuItemImage.HasFile)
{
MyFunction.UploadThisFile(anything)
}
When I upload any image and click on the save button it shows false in FileUpload.HasFile. I am stuck and finding no solution for it.
Any help would be appreciated.
you can try this
<asp:ScriptManager runat="server"></asp:ScriptManager>
<asp:UpdatePanel runat="server" ID="UpdatePanel1" UpdateMode="Conditional">
<ContentTemplate>
<asp:FileUpload runat="server" ID="fuItemImage" Width="370px" TabIndex="12" />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID = "Button1" />
</Triggers>
</asp:UpdatePanel>
add the button id in triggers to upload the file which will do postback

{
ImageButton btndetails = sender as ImageButton;
GridViewRow row = (GridViewRow)btndetails.NamingContainer;
lblId.Text = GridView1.DataKeys[row.RowIndex].Value.ToString();
name0.Text = row.Cells[1].Text;
desig0.Text = row.Cells[2].Text;

mobno0.Text = row.Cells[10].Text;
this.mpedit.Show();
}
The code runs without error but modal popup is not visible. Please help me to find my mistake.
There 3 ways You can use Modal Popup using Update Panel.Try any one of this.
Modal Popup with UpdatePanel inside PopupPanel
<div style="background-color: White">
<asp:Button runat="server" ID="button4" Text="Launch Modal Popup1" />
<asp:Panel runat="server" ID="modalPanel3" Style="display: none">
<asp:UpdatePanel runat="server" ID="updatePanel3">
<ContentTemplate>
<asp:Label runat="server" ID="label4" Text="Label in UpdatePanel"></asp:Label>
<asp:Button runat="server" ID="Button5" Text="Click to Cause postback" OnClick="Button5_Click" />
</ContentTemplate>
</asp:UpdatePanel>

PopupControlID="modalPanel3" OkControlID="Button6" CancelControlID="LinkButton1"
BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>
</div>
2.Update Panel that contains a ModalPopup and its associated PopupPanel inside it
<asp:UpdatePanel runat="server" ID="updatePanel2" UpdateMode="Conditional" ChildrenAsTriggers="true">
<ContentTemplate>
<asp:Button runat="server" ID="button2" Text="Launch Modal Popup2" />
<asp:Panel runat="server" ID="modalPanel2" BackColor="AliceBlue" Style="display: none">
<asp:Label runat="server" ID="label5" Text="Label in UpdatePanel"></asp:Label>

PopupControlID="modalPanel2" OkControlID="okBtn2" CancelControlID="cancelBtn2"
BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>
</ContentTemplate>
</asp:UpdatePanel>
3.Update Panel that contains a ModalPopup; its PopupPanel has an UpdatePanel inside it
<asp:UpdatePanel runat="server" ID="outerUpdatePanel" UpdateMode="Conditional" ChildrenAsTriggers="false">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="outerPanelTrigger" />
</Triggers>
<ContentTemplate>
<asp:Button runat="server" ID="outerPanelTrigger" Text="OuterPanelTrigger" /><br />
<br />
<asp:Button runat="server" ID="button1" Text="Launch Modal Popup3" />

<asp:Button runat="server" ID="updateLabel" OnClick="updateLabel_Click" Text="Click to Cause postback" />
</ContentTemplate>
</asp:UpdatePanel>
<asp:Button runat="server" ID="okBtn" Text="OK" />

BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>

Are you using the latest version of AjaxControlToolkit?
In v16.1 the following bugs were fixed:
Item 27971 - Modal Popup incorrect z-index in tab container and
update panel
Item 28021 - Multiple ModalPopupExtenders z-index
issue
I am doing research to the Modalpopupextender from the Ajax Toolkit.
This code doesn't work, it doesn't open the pop-up. The only thing what happens when I click on the button is: Refreshing the page.
What am I doing wrong? Also tried this with an Updatepanel... Did 3 hours of research before posting this question, please don't blame it on me...
I also used the Toolkitscriptmanager, but that didn't solve it.
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:Button ID="btnTest" runat="server" Text="Button" />
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnTest" PopupControlID="Panel"></asp:ModalPopupExtender>
<asp:Panel ID="Panel" runat="server">
<h1>Hello World!</h1>
</asp:Panel>
Use PostBackTrigger for the button and then check it out .:)
Example:
<asp:UpdatePanel ID="updatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnTest" runat="server" Text="Button" />
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnTest" PopupControlID="Panel"></asp:ModalPopupExtender>
<asp:Panel ID="Panel" runat="server">
<h1>Hello World!</h1>
</asp:Panel>
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="btnTest"/>
</Triggers>
</asp:UpdatePanel>
I've got an updatePanel and a button which triggered in it.
However, the button causes full postback instead of partial one.
Here's my Code:
<asp:Button ID="cEvent" runat="server" Text="צור יום" Width="80px"
Height="40px" Font-Size="Medium" onclick="cEvent_Click" CausesValidation="false"/>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel id = "updatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="cEvent" EventName="Click"/>
</Triggers>
<ContentTemplate>
<div id="yesEve" runat="server" visible="false" style="width:95%; float:right; margin-left:5%; padding-top:20px; margin-bottom:20px;">
<table id="mytable" cellspacing="0" runat="server">
</table>
</div>
<div id="errorMsg" runat="server" visible="false" style="width:100%; text-align:center; float:right;">
<asp:label visible="true" ID="msg1" Font-Size="Medium" runat="server" Font-Bold="true" Text = "היום נמחק בהצלחה"></asp:label>
</div>
<div id="noEve" style="width:100%; padding-top:20px; float:right; text-align:center; margin-bottom:20px;" runat="server" visible="false">
<asp:label visible="true" ID="stamLabel" Font-Size="Medium" runat="server" Font-Bold="true" Text = "לא קיימים ימים פתוחים"></asp:label>
</div>
<asp:LinkButton ID ="remove" runat="server"></asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
I really need some help with that... i'm searching for hours all over the web to find an answer.
Thanks, Matan
In the code behind, you can try adding this line:
ScriptManager.GetCurrent(Page).RegisterPostBackControl(Button1);
There is nothing wrong with your code, you have a conflict somewhere with code(ClientIDs) you haven't show us or a JavaScript error breaking the page.
Here's a template for how to do this from a microsoft tutorial page:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<fieldset>
<legend>UpdatePanel</legend>
<asp:Label ID="Label1" runat="server" Text="Panel created."></asp:Label><br />
</fieldset>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />

I have two update panels at my ajax page. This is first time I'm using updatepanel and I don't know what is wrong. I think only btnFilter's Click event must trigger the second update panel's content but changing combo values (which also hides/unhides btnFilter button) makes second updatepanel change content (at least I see transferred data with firebug & second updatepanel blinks sometimes). Online here.
<asp:UpdatePanel ID="upComparison" runat="server">
<ContentTemplate>
Brand:
<asp:DropDownList ID="ddlBrands" runat="server" AutoPostBack="true"
OnSelectedIndexChanged="ddlBrands_SelectedIndexChanged"
AppendDataBoundItems="true">
<asp:ListItem Value="" Text="Please select a brand..." />
</asp:DropDownList>
<asp:Panel ID="pModels" runat="server" Visible="false">
Model:
<asp:DropDownList ID="ddlModels" runat="server" AutoPostBack="true"
OnSelectedIndexChanged="ddlModels_SelectedIndexChanged" />
</asp:Panel>
<asp:Panel ID="pButton" runat="server" Visible="false">
<asp:UpdateProgress ID="upMain" runat="server" DisplayAfter="100">
<ProgressTemplate><img src="/Assets/Images/loader.gif" />
</ProgressTemplate>
</asp:UpdateProgress>
<asp:Button ID="btnFilter" runat="server" Text="Filter"
OnClick="btnFilter_Click" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID="upList" runat="server">
<ContentTemplate>
<asp:Repeater ID="rProducts" runat="server">
<ItemTemplate>some code here</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnFilter" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
By default, every UpdatePanel will be refreshed during every asynchronous postback.
To change this behavior, set the UpdateMode property to Conditional.
