<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>

i have two form and each form has button , i have abstracted them by two panel so when enter key in each panel pressed , proper button will send .
in one panel i have login form
<asp:Panel ID="pnlRegistered" runat="server" DefaultButton="btnLoginButton">
<LayoutTemplate>
<asp:Button ID="btnLoginButton" runat="server" CommandName="Login" Text="Login" ValidationGroup="Login1" OnClick="btnLoginButton_Click" ClientIDMode="Static" />
</LayoutTemplate>
<asp:Panel>
but i get exception
System.InvalidOperationException
The DefaultButton of 'pnlRegistered' must be the ID of a control of type IButtonControl.
You are missing the value of DefaultButton:
<asp:Panel ID="pnlRegistered" runat="server" DefaultButton="btnLoginButton">
<asp:Button ID="btnLoginButton" runat="server" CommandName="Login" Text="Login" ValidationGroup="Login1" OnClick="btnLoginButton_Click" ClientIDMode="Static" />
<asp:Panel>
EDIT: You can also set the DefaultButton in the code-behind, like so:
pnlRegistered.DefaultButton = btnLoginButton.UniqueID;
put your panel inside layouttemplate of your login control
<asp:Login ID="Login1" runat="server">
<LayoutTemplate>
<asp:Panel ID="pnlRegistered" runat="server" DefaultButton="btnLoginButton">
<asp:Button ID="btnLoginButton" runat="server" CommandName="Login" Text="Login" ValidationGroup="Login1"
ClientIDMode="Static" />
</asp:Panel>
</LayoutTemplate>
</asp:Login>
<div id="TrainingSearchGridContainer" class="mt_20">

<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 an update panel which contains two buttons one is submit and other is cancel.
Now i want when i will click on submit button then progress bar displays.
But when i will click on cancel button it should not display.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<br />
<asp:UpdateProgress runat="server" ID="PageUpdateProgress" DisplayAfter="0" >
<ProgressTemplate>
<img src="../images/ajax-loader.gif" alt="Loading...." /><br />
</ProgressTemplate>
</asp:UpdateProgress>
<asp:LinkButton ID="lnkSubmit" runat="server" CssClass="lnk">Submit</asp:LinkButton>
<asp:LinkButton ID="lnkCancel" runat="server" CssClass="lnk">Cancel</asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
Please help me i am tired to try to solve it.
Thanks ,Rajbir
I have added two update panels to my page. I'm trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.
Code
<asp:ToolkitScriptManager runat="server" ID="ScriptManager" />
<asp:UpdatePanel ID="updatePnl" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:label ID="NoConsignments" runat="server" ForeColor="red" />
<br />
<asp:TextBox ID="StartDate" runat="server" /> <asp:TextBox ID="EndDate" runat="server" /> <asp:Button ID="Dates" OnClick="btDates" runat="server" Text="Search" />
<asp:calendarextender ID="Calendarextender2" targetcontrolid="StartDate" Format="dd/MM/yyyy" runat="server"></asp:calendarextender>
<asp:calendarextender ID="Calendarextender3" targetcontrolid="EndDate" Format="dd/MM/yyyy" runat="server"></asp:calendarextender>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Dates" />
</Triggers>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
I've left out some of the middle code of there is alot. If you would like any more code please let me know.
Am I missing something? or is this not the way that update panels should be used?
Thanks you so much for any help you can provide
I would guess that the validation controls in the second UpdatePanel are firing their client-side validation methods (so the update panel isn't posting back, which is correct).
You might be able to get around this by using the ValidationGroup property - assign the validation controls in the first update panel to one validation group (e.g. "ValidationGroupA"), and the validation controls in the second update panel to another validation group.
I haven't used UpdatePanels for a while, and you haven't included the mark up for the validators in the second panel.
However it looks to me like you might not be adding groups to your validation see this tutorial
e.g.:
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" ValidationGroup="First"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ValidationGroup="First" ErrorMessage="TextBox1 should not be blank"
ControlToValidate="TextBox1"/>
<asp:Button ID="Submit1" runat="server" ValidationGroup="First"
Text="Submit 1"/>
<asp:TextBox ID="TextBox3" runat="server" ValidationGroup="Second"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ErrorMessage=" TextBox3 should not be blank"
ControlToValidate="TextBox3" ValidationGroup="Second"/>
<asp:Button ID="Submit2" runat="server" ValidationGroup="Second"
Text="Submit 2"/>
</div>
</form>
</body>
Hope this helps and I haven't missed the point.
You have to specify ValidationGroups for your Buttons and Validators, f.e. Panel1 for your Searchbutton and Panel2 for your Validators in second UpdatePanel.
<asp:Button ID="Dates" ValidationGroup="Panel1" runat="server" Text="Search" />
....
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ValidationGroup="Panel2" ErrorMessage="RequiredFieldValidator"
ControlToValidate="TextBox1" />
</ContentTemplate>
</asp:UpdatePanel>
I have UserControl and within that control i have asp:ListView. Inside the ListView i have a asp:LinkButton. When i click on the LinkButton the control raises full postback, no matter if the UserControl is inside UpdatePanel or is not.
UserControl:
<asp:ListView ID="lvImages" runat="server" OnItemCommand="lvImages_ItemCommand">
<ItemTemplate>
<div>
<asp:Image runat="server" ID="imgImageThumb" ImageUrl='<%#Eval("Image") %>' GenerateEmptyAlternateText="true" />
<asp:LinkButton runat="server" ID="lbtnImageAdd" CommandName="Add" CommandArgument='<%#Container.DisplayIndex %>'
CausesValidation="false" Text="Add" />
</div>
<ItemTemplate>
</asp:ListView>
Page:
<asp:UpdatePanel ID="up" runat="server">
<ContentTemplate>
<cuc:UserControl ID="cucUserControl" runat=server/>
</ContentTemplate>
</asp:UpdatePanel>
You need to set the properties to let the update panel know what to trigger off of. Try setting ChildrenAsTrigger=true.
