Prevent modal close on asp:textbox enter

I am trying to prevent my modal from closing when keypress enter is entered in my modal asp textbox.
I have tried to wrap the textbox in another update panel and use an asynchronous postback trigger on textchanged, but thats not quite what I'm looking for. I am trying to create a text entry part which only updates when keypress enter is pressed and not when the text changes, I have also tried adding data-dismiss="modal" to the textbox itself like other pages have suggested, but this just means when I click on the textbox it shuts the modal.
<asp:UpdatePanel ID="upd_mdl_console" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<!-- Ryan Console-->
<div class="modal fade" data-dismiss="modal" data-toggle="modal" data-backdrop="static" data-keyboard="false" id="mdl_console" tabindex="-1" role="dialog">
<div class="modal-dialog2" role="document">
<div class="modal-content _dev_console">
<div class="modal-header _dev_console">
<h5 class="modal-title pull-left" id="H1" runat="server">
<asp:Label runat="server" ID="Label3" Text="DEV CONSOLE"></asp:Label></h5>
<button type="button" class="close pull-right" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<br />
</div>
<div class="modal-body">
<div class="panel-heading _dev_console">
<asp:Literal ID="devbox_line_5" runat="server" Text=""></asp:Literal>
<asp:Literal ID="devbox_line_4" runat="server" Text=""></asp:Literal>

</ContentTemplate>
</asp:UpdatePanel>
</div>
<div class="panel-heading _dev_console">
<div class="input-group" style="margin-bottom: 10px; width: 100%">
</div>
</div>
</div>
<div style="clear: both"></div>
<div class="modal-footer _dev_console">
<asp:Label ID="Label4" runat="server" Text="Label" Visible="false"></asp:Label>
<%-- <asp:Button ID="Button1" OnClick="lnk_go_Click" class="btn btn-success" runat="server" AutoPostBack="false" Text="Create"></asp:Button>--%>
<button type="button" class="btn btn-secondary _dev_console" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>

I use the following snippet to disable enter in textboxes. This also prevents triggering of a form post when pressing enter inside a textbox. It might work for preventing the closure of the modal also.
$('input').keypress(function (e) {
return e.keyCode !== 13;
});
If you want to disable the enter in the modal only you could do something like this
$('.modal-body input').keypress(function (e) {
return e.keyCode !== 13;
});

Why does not the CommandArgument of a button inside a ModalPopupExtender with AsyncFileUpload work?

I've been trying for a while to find out the reason why the CommandName of a button does not work, in truth I always throw it empty when entering the onCommand event and even onClick of the same button despite putting the property with a value, the strange of the case is that I can not modify the property and putting the property CommandName works without problem the first time, however it is impossible for me to modify its value.
To start I have a ModalPopupExtender together with a Panel which has a series of TextBox and an AsyncFileUpload with a series of buttons, it is necessary to bear in mind that I am working on an ASPX form, son of a MasterPage:
<cc1:ModalPopupExtender ID="mpEditUser" runat="server" PopupControlID="pnEditUser" TargetControlID="lbShowEditUser"
CancelControlID="lbCloseEditUser" BackgroundCssClass="modalBackground">
<Animations>
<OnShown>
<FadeIn Duration="0.40" Fps="30" />
</OnShown>
<OnHiding>
<FadeOut Duration="0.40" Fps="30" />
</OnHiding>
</Animations>
</cc1:ModalPopupExtender>
<asp:Label ID="lbShowEditUser" runat="server" Text="" style="display:none;"></asp:Label>
<asp:Label ID="lbCloseEditUser" runat="server" Text="" style="display:none;"></asp:Label>
<asp:Panel ID="pnEditUser" runat="server" ClientIDMode="Static" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">

</div>
<div class="modal-body">

<asp:Button ID="btnCloseEditUser" runat="server" AutoPostBack="true" CausesValidation="true" Text="Close" class="btn btn-default" data-dismiss="modal" OnClick="btnCloseEditUser_Click" aria-hidden="true" />
<asp:Button ID="btnEditParticipant" runat="server" AutoPostBack="true" CausesValidation="true" Text="Update User" class="btn btn-primary" data-dismiss="modal" OnClick="btnEditUser_Click" aria-hidden="true" />
</ContentTemplate>
</asp:UpdatePanel>

</div>
</div>
</asp:Panel>
Event onCommand:
protected void btnDownloadCVUser_Command(object sender, CommandEventArgs e)
{
string x = e.CommandArgument; <- (this value is always "")
}
To get out of doubt, I decided to put the "btnDownloadCVUser" control out of the Panel
............
</asp:UpdatePanel>
</div>
</div>
</div>
</asp:Panel>
<asp:Button ID="btnDownloadCVUser" runat="server" CssClass="btn btn-default" ClientIDMode="Static" CommandArgument="Test" OnCommand="btnDownloadCVUser_Command" Text="Download" />
This worked successfully on the CommandArgument, that is, I could see its assigned value on the label and manage to modify its value.
I tried to put UpdatePanel together with the AsyncFileUpload in such a way that it encloses the "from-group" with the triggers but I keep presenting the same problem. It's very strange because I have a button that does exactly the same thing but it's NOT in a MomalPopupExtender
Why does this happen?
Does ModalPopupExtender or AsyncFileUpload have something to do with the problem?
Does the level of the "form-group" have anything to do with it?
So far the only lifeguard I have is to use ViewState, but I'm still intrigued by the reason that causes my problem :(
Update 01:
I have noticed that the reason seems to be the method with which I load the files (AsyncFileUpload), apparently if I try to change a variable for this it turns out that it is as if I did not, but it allows me to upload the files without problem. Is there any solution?
private int a = 0;
protected void fuCVUser_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
a = 10; < - The value changes to '10' but if I enter the event of another button of the ModalPopupExtender the value is still '0'
}

After seeing this question:
Persisting variable after AsyncFileUpload call to OnUploadedComplete
I have come to the conclusion that it is enough to use a static global variable or Session :)
Apparently the AsyncFileUpload method works with static variables which could justify the problem with CommandArgument

ASP Webforms Validation control not working

Please help the regex Validator is not work when I click the button .
<div class="panel-body">
<div class="form-group">
<div class="input-group">
<asp:Label runat="server" ID="lblAddBranch" Text="Branch Name"
CssClass="text-primary small" AssociatedControlID="txtBranchName" />
<asp:RegularExpressionValidator ID="RegExp1"
runat="server" ErrorMessage="Branch Name must be between 3 to 12 characters"
ControlToValidate="txtBranchName" ValidationExpression="^[a-zA-Z]{3,12}$" ValidationGroup="grpBranch" />
</div>
<asp:TextBox runat="server" ID="txtBranchName" CssClass="form-control input-sm" ValidationGroup="grpBranch" />
</div>
<asp:Button runat="server" ID="btnAddBranch" Text="Add" CssClass="form-group-btn btn btn-sm btn-primary"
OnClick="btnAddBranch_Click" ValidationGroup="grpBranch" />
</div>

Code is working perfect. As per your expression its means that a-z and A-z and 3-12 digit will accept. So when you enter only 12 in your text box the validation will be fire.
To check required field validation you need add Requirefield validation control in you code.

Why ScriptManager causes postback on RequiredFieldValidator in ASP.NET (Web Forms)?

Before adding the ScriptManager when I was clicking on the login button it was showing the required field warning without page postback but after that it has started to do postback first and then validate fields.
It's required to add a ScriptManager when there is an UpdatePanel on the page.
How can I fix this so it doesn't postback on RequiredFieldValidator?

I appreciate your efforts in reaching a solution for my problem.

I came across the same issue a while back and was able to resolve it via Page.Validate();.
Basically, before I added ScriptManager everything was working well. When I would click the update button, the field validators would run and prevent a post back until requirements were met. After adding ScriptManager tag, the page would post back rendering my validators pretty much useless.
What I did was add on my update (submit) button click event:
page.validate();
if (Page.IsValid)
{
// Your update or submit code here.
}
This seems to work fine!

Write like this..
<asp:updatepanel id="LoginModalUpdatePanel" runat="server">
<ContentTemplate>
//paste all codes inside here
</ContentTemplate>
</asp:updatepanel>

How to use dropdownlist of asp.net as input-group in bootstrap

I have a problem in adding dropdownlist in input group..
I use this one..
<div class="input-group">
<div class="input-group-btn">
<asp:DropDownList runat="server" CssClass="selectpicker form-control">
<asp:ListItem Value="Val">Item1sadfasdf</asp:ListItem>
<asp:ListItem Value="Val3">Item2asdfasd</asp:ListItem>
</asp:DropDownList>
</div>
<asp:TextBox CssClass="form-control" ID="txtSearch" runat="server"></asp:TextBox>
<span class="input-group-btn">
<asp:Button CssClass="btn btn-info" runat="server" Text="Search" ID="btnSearch" OnClick="btnSearch_Click" />
</span>
</div>
but it just give me a result like this:
I also got a code like this..
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown"><span runat="server" id="spanCategory">All Category</span>&nbsp&nbsp<span class="caret"></span></button>
<ul id="myMenu" class="dropdown-menu">
<li>All Category</li>
<li class="divider"></li>
<li>JO Number</li>
<li>Date</li>
<li>Status</li>
<li>Client Name</li>
<li>Institution</li>
<li>Department</li>
<li>Location</li>
<li>Priority</li>
<li>Problem</li>
<li>Remark</li>
<li>Assigned</li>
<li>CITI Department</li>
</ul>
</div>
<asp:TextBox CssClass="form-control" ID="txtSearch" runat="server"></asp:TextBox>
<span class="input-group-btn">
<asp:Button CssClass="btn btn-info" runat="server" Text="Search" ID="btnSearch" OnClick="btnSearch_Click" />
</span>
</div>
and showed me output like this..
It is what i want but the problem is that everytime i click the search button which do the post back, it just change the value into a default value which is the "All Category" value.. The value is just change through jQuery but everytime a postback is done the value back to default so i decided to use dropdownlist which retain its value even if there is a post back happen.. but the design is not that good..
How to make it same as the design i liked.. Thank you so much

To use DropDownList as an input group you need code like this:
<div class="input-group">
<asp:DropDownList ID="DD1" runat="server" CssClass="form-control" AutoPostBack="true" />
<span class="input-group-btn">
<button id="btn" class="btn btn-default" type="button">Reset</button>
</span>
</div>
The problem you have is a textbox within the input-group div tag as well as the dropdown. This is causing them both to display and your button to span two lines.
