I have the following code :
<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode="Conditional" Visible="true" RenderMode="Inline">
<ContentTemplate>
<tr>
<td>
<asp:CheckBox ID="CheckBoxTel" Text="Phone" runat="server" AutoPostBack="true" />
</td>
</tr>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="CheckBoxTel" EventName="CheckedChanged" />
</Triggers>
</asp:UpdatePanel>
I would like to not refresh the page when a checkbox is checked or unchecked that's why I use a trigger but I'm new to update panel and trigger and I'm not sure why when I click on my submit button that refreshes the page, the checkbox keeps unchecked even if I checked it. Do I have to bind something to the button ?
Here is the button code :
<asp:Button ID="Search" runat="server" Text="Search" CssClass="btn btn-primary" OnClick="Search_OnClick" />

I have a very simple form that I am using in a web forms website. The form is embedded in an ascx control and it is re-used throughout the site in various pages. It was working fine until we decided to implement server-side validation using an ajax postback. So, I added update panels and triggers and everything works fine if I use the form from my Default.aspx form, but it doesn't work from any other page. I have been googling this for two days and so far I cannot figure out if this is an ASPX problem, or if it is an IIS configuration problem. I am very much stuck.
This is the form ( it is incredibly simple ). The form resides in an ASCX user control
<asp:UpdatePanel ID="AllFormFields" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div>
<asp:TextBox ID="txtFirstName" runat="server" placeholder="First Name"></asp:TextBox>
</div>
<div>
<asp:TextBox ID="txtLastName" runat="server" placeholder="Last Name"></asp:TextBox>
</div>
<div>
<asp:TextBox ID="txtEmail" runat="server" placeholder="E-Mail" TextMode="Email"></asp:TextBox>
</div>
<div>
<asp:TextBox ID="txtPhone" runat="server" placeholder="Phone" TextMode="Phone"></asp:TextBox>
</div>
<div>
<asp:DropDownList ID="rcbPrimarySpecialty" runat="server" EmptyMessage="Primary Specialty"></asp:DropDownList>
</div>
<div>
<asp:TextBox ID="txtComments" Rows="10" TextMode="MultiLine" runat="server" placeholder="Comments"></asp:TextBox>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
<div>
<asp:Button ID="btnSubmit" runat="server" Text="Request Info" CausesValidation="true" ClientIDMode="AutoID" />
</div>
<div>
<asp:UpdatePanel ID="ValidationMessagePanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lblValidationMessage" runat="server" Text=""></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</div>
The idea is that the user clicks the button btnSubmit and ajax calls its click handler.
When I use the site under my VS debugger, the click handler is not even called. Something else is interfering with the Ajax call and the postback never happens.
<asp:Button ID="newbutton" runat="server" Text="Click" onsubmit="button_click" OnClick="button_click" />
I have this button in update panel and i want it to work on enter not only onclick it works in google chrome , but not in ie what should I do?
On the panel set the default button to the id of the button
<asp:Panel runat="server" id="examplePanel" DefaultButton="newbutton">
Set the default button for update panel with the Id of this button
Sample:
<asp:UpdatePanel ID="upTest" runat="server">
<ContentTemplate>
<asp:Panel runat="server" ID="pTest" DefaultButton="newbutton">
<asp:Button ID="newbutton" runat="server" Text="Click" onsubmit="button_click" OnClick="button_click" />
ASP:Button cannot work with enter because it has OnClick. To react on enter properly you should use ASP:Panel with DefaultButton property. You need to have focus on control inside asp:Panel for example TextBox
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Panel ID="Panel1" runat="server" DefaultButton="newbutton">
<asp:TextBox ID="TxtUserLogin" runat="server" TabIndex="1" Text="login" />
<asp:Button ID="newbutton" runat="server" Text="Click" OnClick="button_click" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
<div id="TrainingSearchGridContainer" class="mt_20">
<asp:UpdatePanel runat="server" ID="UpdatePanelCountryRegions" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList runat="server" ID="ProductDropDown"></asp:DropDownList>
<asp:DropDownList runat="server" ID="DateDropDown"></asp:DropDownList>
<asp:DropDownList runat="server" ID="CountryDropDown" AutoPostBack="True" OnSelectedIndexChanged="LoadRegions"></asp:DropDownList>
<asp:DropDownList runat="server" ID="StateDropDown"></asp:DropDownList>
<asp:LinkButton ID="SearchBtn" runat="server" OnClick="StartSearch">
<span class="blueButton2css3"><span class="btnspan">
<asp:Literal ID="SearchButtonText" runat="server"></asp:Literal></span></span>
</asp:LinkButton>
</ContentTemplate>
<Triggers>
<asp:asyncpostbacktrigger controlid="SearchBtn" eventname="Click" />
But for some reason when I click on the button nothing happens, If I remove the update panel the button works fine.
The problem is that you are using AsyncPostBackTrigger instead of PostbackTrigger. AsyncPostBackTrigger is used when the control is outside the update panel, your linkbutton is present inside the update panel so you should use PostBackTrigger.
<asp:PostBackTrigger ControlID="SearchBtn" />
I have the following ModalPopupExtender that contains an AJAX ComboBox, RequiredFieldValidator, and ValidatorCalloutExtender. Outside of the ModalPopup this exact code works. Also, ValidatorCalloutExtender's in the ModalPopup work on other controls like TextBoxes. However the following does not work. The value '0' (default) can be selected and the validator does not display.
However if I take out the AJAX ComboBox and put in a traditional ASP.NET DropDownList instead, it works as expected and shows the ValidatorCalloutExtender. I have used the developer toolbar and can't see anything out of the ordianry.
What do I need to do to make the ValidatorCalloutExtender work with the AJAX ComboBox inside the ModalPopup?
Thanks!
Not working:
<asp:Panel ID="pnlData" runat="server" >
<table>
<tr>
<td>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<act:ComboBox ID="cbx1" runat="server" Width="278px" DropDownStyle="DropDownList" AutoCompleteMode="SuggestAppend" CaseSensitive="false" AppendDataBoundItems="true" ToolTip="Select the Name.">
<asp:ListItem Text="(Please Select the Name)" Value="0" />
</act:ComboBox>
<asp:RequiredFieldValidator ID="cbx1Req" runat="server" ControlToValidate="cbx1"
SetFocusOnError="true" ErrorMessage="Please Select the Name."
InitialValue="0" Display="None" />
<act:ValidatorCalloutExtender ID="cbx1ReqE" runat="server"
TargetControlID="cbx1Req" PopupPosition="Right" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnAdd" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</td>
</tr>
</table>
</asp:Panel>
<act:ModalPopupExtender ID="DataMPE" runat="server"
TargetControlID="="btnHidden"
PopupControlID="pnlData" />
<asp:Button ID="btnHidden" runat="server" Text="Modal Display (Hidden)" style="display:none" />
Works (if I replace the AJAX ComboBox control in code above with a traditonal ASP.NET DropDownList):
<asp:DropDownList ID="cbx1" runat="server" Width="300px" AppendDataBoundItems="true">
<asp:ListItem Text="(Please Select A Name)" Value="0" />
</asp:DropDownList>
Don't know if this can help, I had this problem with a required validator.
If found a solution here: http://ajaxcontroltoolkit.codeplex.com/workitem/24417
Had to add javascript to change the controltovalidate property for the internal textbox.
string script = string.Format(#"if({0}) {0}.controltovalidate = ""{1}_TextBox"";", this.reqValidator.ClientID, this.ddlCombo.ClientID);
ScriptManager.RegisterStartupScript(this, this.GetType(), string.Format("validator trick for {0}", this.ClientID), script, true);
I have a button is inside a another table(s) inside the update panel.
<Update panel>
<ContentTemplate>
<table>
<table>
<Button>
<table>
<table>
</ContentTemplate>
</Update panel>
I would like to add a button to Update panel's trigger.

PostBackTrigger example:
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btn1" runat="server" Text="Button 1-Partial Postback" />
<asp:Button ID="btn2" runat="server" Text="Button 2-Full Postback" />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="btn2" />
</Triggers>
</asp:UpdatePanel>
