Would like to validate more than one control on one button click. I would like something to validate whether a textbox has contents if a checkbox is checked or not but the checkbox doesn't necessarily have to be checked and in that case I don't want to check the textbox. I tried validation group but each button needs to control the different groups and i need this all to be under one button.
I'm open to ideas of how to do this c#,javascript...etc. Heres some code: Button3 is the save which validates whether checkbox 1 is checked and if so textbox10 cant be empty. I have about four other instances of this but are independent of each other.
<asp:Button ID="Button3" runat="server" Height="24px"
Text="Save" Visible="False" Width="67px" Font-Bold="True"
causesvalidation="true"
validationgroup="required"
runat="Server" />
<asp:CheckBox ID="CheckBox1" runat="server"
oncheckedchanged="CheckBox1_CheckedChanged" Text=" Breach Letter Sent"
ValidationGroup="required" AutoPostBack="True" Enabled="False" />
You want to use the CustomValidator control which can validate both on the server and the client. There is an example in the docs here - http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.customvalidator.aspx
I would never do form validation in JavaScript. Believe it or not, but some people actually turn off JavaScript! Use validators to validate the field content. Of course this means a round trip to the server in most cases, but you get reliable and well integrated validation.
you can use validation with Ajax (in Ajax postback occures but you will not sense)

I have a login page in my asp.net website (using C#) and it has a "login form" which has an email text box, a password text box and a login button.
In addition, I have a "search form" at the top of the web page which has a search text box and a search button.
*All of the controls are in the same form because of the asp.net limit for one runat="server" form.
The problem is that when I type something to search for and click ENTER (and not directly the button) it doesn't do anything, only runs the Page_Load again. Same thing when I click ENTER in the login section instead of directly on the login button.
I have tried different solutions but they were problematic because of the different functionality of the two "forms".
I have no idea how to solve this, any suggestions?
my web forms is a little rusty but I think something like this:
<asp:Panel ID="loginPanel" runat="server" DefaultButton="loginButton">
<%-- Login Stuff--%>
<asp:Button ID="loginButton" runat="server" />
</asp:Panel>
<asp:Panel ID="loginPanel" runat="server" DefaultButton="searchButton">
<%-- Search Stuff --%>
<asp:Button ID="searchButton" runat="server" />
</asp:Panel>
should work
Only one form with runat='server' available on aspx page. So, if you really need another form, you may use its without runat='server' and use for search jQuery ajax call.
I have a searchbar on my site, but the problem is that when the user is in their profile I display a changepassword asp.net object. I'm using Visual Studio 2012.
<asp:ChangePassword ID="ChangePassword1" runat="server" SuccessTextStyle-HorizontalAlign="Center" CancelButtonText="" CancelButtonType="Link" ContinueButtonText="" ContinueButtonType="Link">
</asp:ChangePassword>
When I try to add my searchbar
<asp:TextBox ID="txtSearch123" runat="server" OnTextChanged="txtSearch123_TextChanged" Width="217px" Text="Search for an item..." OnClick="this.value=''" AutoCompleteType="Disabled"></asp:TextBox>
When the user presses enter, the search never completes because the textboxes inside in the change password are empty and they light up as if the user is trying to change their password. Even though they aren't linked what so ever.
Any ideas?
Following Works:
<asp:ChangePassword ID="ChangePassword2" runat="server" ValidationGroup="Password"> </asp:ChangePassword>
<asp:TextBox ID="txtSearch123" runat="server" OnTextChanged="txtSearch123_TextChanged" Width="155px" Text="Search for an item..." OnClick="this.value=''" AutoCompleteType="Disabled" ValidationGroup="SearchItem"></asp:TextBox>
<asp:Button ID="btnSearch" runat="server" Text="" Width="0" Height="0" ValidationGroup="SearchItem" Visible="false" />
IF that does not work, do the following...
Make a button with the same validation as the text box.
Set the height and width to the button to 0.
Set the border type to none
Set the background of the button to the background you are trying to place it on.
Boom, your button is hidden in plain sight and your validation group still works.
<asp:TextBox ID="txtSearch123" runat="server" OnTextChanged="txtSearch123_TextChanged" Width="217px" Text="Search for an item..." OnClick="this.value=''" AutoCompleteType="Disabled" ValidationGroup="SearchItem"></asp:TextBox>
<asp:Button ID="btnSearch" runat="server" Text="" Width="0" Height="0" ValidationGroup="SearchItem" BackColor="#5F605F" BorderStyle="None" />
There's two concepts you need to understand first.
The fact is, that everything on a (normal) ASP.NET page is inside one single form. This also means that things like "pressing enter to send form" are a bit tricky, since they submit the whole form, which usually isn't what you want.
Now to the concepts:
ValidationGroup - this setting on .NET validators (and buttons etc.) allows you to separate different logical forms inside the one superform. The validators will only evaluate if the originator of the submit action (eg. the "change password button") is in the same ValidationGroup. Properly configuring validation groups should make this part of your issue disappear.
What happens on enter key press - by default, you send the whole form, without doing any button's action. So, if you have multiple logical forms on one page, you have to put each inside its own Panel, which has a DefaultButton property, which says "if I press enter inside this panel, it will act as if I clicked on this button".
SET ValidationGroup in your TextBox
<asp:TextBox ID="txtSearch123" runat="server" OnTextChanged="txtSearch123_TextChanged" Width="217px" Text="Search for an item..." OnClick="this.value=''" AutoCompleteType="Disabled" ValidaionGroup="Something"></asp:TextBox>
Specifying Validation Groups
I have ASP.NET WebForms application. One of it's pages is dynamically created table with RegularExpressionValidator. Above of table there are several LinkButtons, which manages navigation of application. But if I put invalid value to textbox in table, Page.IsValid is set to false and all controls on page are blocked.
So, how can I unblock buttons even if validator set Page.IsValid to false? Thnak you.
You could use ValidatorGroups to separate the validations.
Assuming you want to "unblock" the link buttons used for navigation, you can use:
CausesValidation="False"
in the ASPX markup for the link button.
Example:
<asp:LinkButton ID="btnBack" runat="server" data-transition="fade" CausesValidation="false"
data-theme="b" data-icon="" Text="Back" onclick="btnBack_Click" />
I have an ASP.net page.
That has an Ajax Toolkit Tab Control.
That has tabs.
That have custom ascx controls I wrote.
I have a text box that perform a search action. It is declared like this:
<asp:TextBox ID="txtPrereqSearch" runat="server"
ontextchanged="txtPrereqSearch_TextChanged"></asp:TextBox>
Nothing fancy. This format has been working for months. There's no submit button. It just posts back when I hit enter. The problem appeared when I added a second custom control using the same type of feature. Now browsers don't postback when I type something in either of these textboxes and press enter.
It seems that browsers have a default way of handling one textbox in one form, but that behavior changes when the number reaches two.
Is there an easy way around this? I guess I can create a hidden submit button but it seems like there is probably a better way to deal with this when the functionality is in two separate custom controls.
Your feedback is appreciated!

The default behavior with no submit button seems to depend on the browser, and the behavior can indeed depend on the number of input controls.
I would add hidden "submit" button (e.g. style="display:none;") which should ensure that it always gets submitted.
The answer was a little different than I expected, but philosophically like my original idea that #jamietre reinforced.
I had to surround the controls with an <asp:Panel> tag with a DefaultButton attribute. A-like-a so:
<asp:Panel ID="ButtonPanel" runat="server" DefaultButton="btnSubmit">
<asp:Label ID="Label1" runat="server" Text="Course:"></asp:Label>
<asp:TextBox ID="txtPrereqSearch" runat="server"
ontextchanged="txtPrereqSearch_TextChanged"></asp:TextBox>
<asp:TextBoxWatermarkExtender ID="txtPrereq_TextBoxWatermarkExtender"
runat="server" Enabled="True" TargetControlID="txtPrereqSearch"
WatermarkCssClass="Watermark" WatermarkText="e.g., MATH201"></asp:TextBoxWatermarkExtender>
<asp:Button ID="btnSubmit" CssClass="InvisibleSubmit" runat="server" Text="Submit" OnClick="txtPrereqSearch_TextChanged"/>
</asp:Panel>
I have got a page that has 2 "forms" (What I mean by a form here is a Panel consisting of: textboxes, validators and a button).
(I got 2 here because one of them is actually on the MasterPage, shown all the time)
The problem is when you try to submit to one of the form, it will validate the other form, which of course is blank and invalid.
How do you solve this problem?
Thank you.
Your problem can be solved with asp.net ValidationGroups.
http://weblogs.asp.net/scottgu/archive/2004/10/24/246945.aspx
Basically, you group the controls to be validated using a uniquely named validation group. Like so:
<asp:Textbox ID="txt" runat="server" />
<asp:RequiredFieldValidator id="rfv" runat="server" ControlToValidate="txt" ValidationGroup="masterGroup">* Required!</asp:RequiredFieldValidator>
<br />
<asp:Button id="btnSubmitMaster" runat="server" Text="Submit!" ValidationGroup="masterGroup" />
If you group your inputs like this, then assign the validation group to the control that submits the form, the inputs in the other validation groups won't be validated.
