I have a validation summary inside a asp.net formview and the validators just don't seem to trigger the validation summary.
Things I already tried:
Enable the ViewState on everything.
Set the ClientID to static.
Set the ValidationGroup to the same group on both all validators and the summary.
Used Google to search for a solution.
Anyone has any ideas on how to handle this?
Code. Formview declaration:
<asp:FormView ID="FormViewPerson" runat="server" DataSourceID="ObjectDataSourcePerson"
DefaultMode="Edit" OnItemUpdating="FormViewPerson_ItemUpdating" OnItemCommand="FormViewPerson_ItemCommand"
OnItemUpdated="FormViewPerson_ItemUpdated" Width="100%">
Any of the textboxes with the validator:
<td> <asp:TextBox ID="NumberTextBox" runat="server" Text='<%# Bind("Number") %>'
TabIndex="10" CausesValidation="True" ClientIDMode="Static" />
<asp:RequiredFieldValidator ID="RequiredFieldValidatorNumber" runat="server" ControlToValidate="NumberTextBox"
ErrorMessage="Number is Required" ForeColor="Red"
ValidationGroup="EditPerson">*</asp:RequiredFieldValidator>
</td>
And the submitbutton:
<asp:ValidationSummary ID="ValidationSummaryPerson" runat="server"
ForeColor="Red" ClientIDMode="Static" CssClass="validation"
ShowMessageBox="True" ValidationGroup="EditPerson" ViewStateMode="Enabled"
/>
<asp:Button ID="UpdateButton" runat="server" CausesValidation="True" CommandName="Update"
Text="Save" ValidationGroup="EditPerson" CssClass="ButtonStyle" TabIndex="90" />
<asp:Button ID="EditCancelButton" runat="server" CausesValidation="False" CommandName="Cancel"
Text="Cancel" CssClass="ButtonStyle" TabIndex="100"
ValidationGroup="EditPerson" />
Hope the CausesValidation for the button is set to true.
Well, I fixed the issue. If anyone else encounters this problem try the following:
Ensure there is only one (1) validation group on the entire form.
Set "causesvalidation" to "true" on the submitbutton.
Check, double check and triple check the spelling of your validationgroup property on all relevant controls.
Be on the lookout for javascript errors in your client-side scripts. They can cause havoc.

I'm still trying to understand and find a solution to the following problem :
I have a custom validator :
<asp:CustomValidator
ID="CustomValidator" runat="server"
OnServerValidate="CustomValidator_ServerValidate"
Forecolor="Red" Display="dynamic"
style="margin-top:10px; margin-bottom:10px"
ValidationGroup="test">
I have a button which call this custom validator :
<asp:Button ID="ButtonSave" UseSubmitBehavior="false"
ValidationGroup="test" Enabled="false" runat="server"
Text="Valider modifications" OnClick="ButtonSave_Click"
CssClass="btn ButtonSave" Width="200px"
style="margin-right:5px; margin-bottom:10px; margin-top:10px" />
and I have also a CheckBox with an event:
<td class="transparent">
<asp:CheckBox ID="Type_CheckBoxCancel"
Text="Cancel" runat="server" CssClass="EntreeCheckbox"
TextAlign="Right" OnCheckedChanged="Type_CheckBoxCancel_CheckedChanged"
AutoPostBack="true" />
</td>
If I click directly on ButtonSave, my custom validator is correctly called and I can do all checks. However, when I click on my CheckBox then on my button, my custom validator is not called anymore. I don't really understand this behavior.
If someone could propose me a solution, please?
I have a strange problem, but I can't get a solution:
We use the Infragistics WebDataGrid, in which I set a dropdown and a textbox.
For both of them I set a requiredfieldvalidator:
<asp:RequiredFieldValidator ValidationGroup="attrib" runat="server" ControlToValidate="ddlIndRoleAttribType" ToolTip="Attribute Type is not set." InitialValue="-- not selected --" Text="!" Display="Dynamic" />
</div>
</ItemTemplate>
</ig:TemplateDataField>
<ig:TemplateDataField Header-Text="Value" Key="IndRoleAttribVal" Width="50%">
<ItemTemplate>
<div>
<stgwc:TextEdit runat="server" Width="300px" ID="txtIndRoleAttribValue" />
<asp:RequiredFieldValidator ValidationGroup="attrib" runat="server" ControlToValidate="txtIndRoleAttribValue" Width="90%" ToolTip="Attribute Value is not set." Text="!" Display="Dynamic" />
</div>
</ItemTemplate>
</ig:TemplateDataField>
<ig:TemplateDataField Header-Text="Action" Key="IndRoleAttribAction" Width="40px">
<HeaderTemplate>
<stgwc:ImageLinkButton runat="server" ID="btnCreateNewAttribute" CausesValidation="false" ImageUrl="~/Images/base/Icons/16x16/add2.png"
ToolTip="Add new Attribute" CommandName="Create" />
<stgwc:ImageLinkButton runat="server" ID="btnSaveAllAttributes" ValidationGroup="attrib" ImageUrl="~/Images/base/Icons/16x16/disk_green.png"
ToolTip="Save all Attributes" CommandName="Save" />
<stgwc:ImageLinkButton runat="server" ID="btnCancelChanges" CausesValidation="false" ImageUrl="~/Images/base/Icons/16x16/undo.png"
CommandName="Cancel" ToolTip="Discard changes" />
</HeaderTemplate>
<ItemTemplate>
<stgwc:ImageLinkButton runat="server" ID="btnDeleteAttribute" CausesValidation="false" ImageUrl="~/Images/base/Icons/16x16/delete2.png"
ToolTip="Delete this Attribute" CommandName="Delete" CommandArgument='<%# Bind("IR_ATTR_ID") %>' />
</ItemTemplate>
</ig:TemplateDataField>
</Columns>
</stgwc:WebDataGrid>
I do a postback if a new item should be created, then I set it to the datasource and reload it, something like this:
dgrIndRoleAttributes.ClearDataSource();
dgrIndRoleAttributes.Rows.Clear();
dgrIndRoleAttributes.DataSource = null;
dgrIndRoleAttributes.DataSource =
(Session[Constants.Session.RoleAttributes.ToString()] as List<TmpIndRoleAttribute>);
dgrIndRoleAttributes.DataBind();
Now comes the funny part: When I press enter after adding a new row, Firefox (only Firefox, on IE it works proper), seems to think the validators on the validator-group attrib arent set proper and I need to click twice, to make it save.
If I check this with the firebug, I see both validators being on display: none, so this cant be problem. As said, this happens only on Firefox, and I cant reproduce it on a small testsample.
Has anyone a idea, what could cause this behavior? Since I'm not used to this validators, I can't imagine, what could cause this problems.
Thanks for you response!

Edith says: It's a infragistics bug... Another one... I use in this case the normal asp textbox and change the style with some css.
.aspx
<asp:TextBox ID="txtInvite" Width="170px" Height="20px" runat="server"
Font-Size="Small" ></asp:TextBox>
<AjaxToolkit:TextBoxWatermarkExtender ID="tbexInvite"
runat="server" SkinID="skinTextBoxWatermarkExtender"
TargetControlID="txtInvite" WatermarkText="Email"></AjaxToolkit:TextBoxWatermarkExtender>
<asp:RequiredFieldValidator ID="rfvInvite" runat="server"
Display="None" ValidationGroup="Inivitation" SetFocusOnError="true"
ControlToValidate="txtInvite" ErrorMessage="Enter Email."></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="regExpInvite" runat="server"
Display="None" ValidationGroup="Inivitation" SetFocusOnError="true"
ValidationExpression="\s*\w+([-+.]\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*\s*"
ControlToValidate="txtInvite" ErrorMessage="Invalid Email Format."></asp:RegularExpressionValidator>
<div class="ButtonLogin" style="margin-top:-27px;margin-right:143px;_margin-right:105px;">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:Button ID="btnInvite" runat="server" CssClass="cssLoginButton blue" Text="Invite" ToolTip="Invite" ValidationGroup="Inivitation" CausesValidation="true" onclick="btnInvite_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1" DisplayAfter="0">

<asp:Image ID="Image1" ImageUrl="~/App_Themes/Lifetrons/images/progressbar.gif" AlternateText="Processing" runat="server" />
</ProgressTemplate>
</asp:UpdateProgress>
Page_load Code
.CS
this.btnInvite.Attributes.Add("onclick", "this.disabled=true;" + Page.ClientScript.GetPostBackEventReference(this.btnInvite, "").ToString());
I want to disable button after clicking on it with maintaining validation and Onlick method. I refer to this question my problem is same like this question but I haven't solve my problem. How can I solve?
There is no need to mess around with your code-behind Page_Load event. In your button control, just add the following snippet:
OnClientClick="if(Page_ClientValidate('Inivitation')){this.disabled=true;}"
So that your button looks like
<asp:Button ID="btnInvite" runat="server" CssClass="cssLoginButton blue" Text="Invite"
ToolTip="Invite" ValidationGroup="Inivitation" CausesValidation="true"
onclick="btnInvite_Click" OnClientClick="if(Page_ClientValidate('Inivitation')){this.disabled=true;}" />
You should be able to disable the button using the Button_Click method. Make your first line something like this:
Button.Enabled = False;
There is a problem with this method though. If the page loads too quickly or the code freezes it will not disable the button properly. Just remember to re-enable the button at the end of the method if the validation fails or times out.
Another method you may try is to hide it using CSS. I am a big fan of this because it always works and it is very simple. You need a technology like jQuery where you can add classes on the fly. You can use the AddClass and RemoveClass API in jQuery to add/remove CSS classes at runtime. Take a look here. http://jqueryui.com/addClass/
you can use Like this
<asp:Button ID="btnInvite" runat="server" CssClass="cssLoginButton blue" Text="Invite" ToolTip="Invite" ValidationGroup="Inivitation" CausesValidation="true" UseSubmitBehavior = False"onclick="btnInvite_Click" />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" Height="146px"
Width="308px">
<Columns>
<asp:TemplateField HeaderText="Original Price" ControlStyle-Width="100px">
<ItemTemplate>
<asp:TextBox ID="txtOriginalPrice" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfv" runat="server" ControlToValidate="txtOriginalPrice"
ValidationGroup="GridView1" Display="Static" ErrorMessage="" Text="*"></asp:RequiredFieldValidator>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I am using above code but its not working though I have put requirefield validator it does not show me the '*'
Yes, your requiredfieldvalidator is certainly there, and it knows which control to validate.What is missing is "when to validate that control".And to answer this question you need to add your textbox the same ValidationGroup with your requiredfieldvalidator and also the control(this can be a button for example) causes to do a validation.So your code will be like
<%--<asp:Button ID="Button1" runat="server" ValidationGroup="GridView1" Text="Benjamin"...Somewhere in your code--%>
<asp:TextBox ID="txtOriginalPrice" runat="server" ValidationGroup="GridView1"></asp:TextBox>
So don't forget these question
What to validate?(a textbox)
When to validate?(after a button click)
After what action try to validate?(a button click)
With what to validate?(a requiredfieldvalidator)
All of these controls must have the same ValidationGroup.
In case you need the validation to be performed then check for something like this
<asp:Button ID="btnAdd" runat='server' ValidationGroup='GridView1' CausesValidation='true'.....
So now when you click the add button it will validate for those controls falling under the validation group you mentioned else the default value is "" hence you won't find any validation triggered.
Add ValidationGroup to TextBox (txtOriginalPrice), Button and other controls.
I have a textbox and I have set required validationcontrol on it on click of a button.
<asp:TextBox runat="server" ID="name" Width="120"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvname" runat="server" ControlToValidate="name" ErrorMessage="Name is required" Display="Dynamic" />
</td>
but the problem is when I am clicking on modify shared webpart and when I click on APPLY or OK button it is not saving as my form is empty . and I can't put
CausesValidation="false" on that button as this button is by default in sharepoint.
Any idea how to resolve this...?
You can use the ValidationGroup property to group all the Validators and validation fields together.
Yes using the ValidationGroup tag will help to relate the controls in a single form and will tell the submit button which fields are associated. Also make sure you have a ValidationSummary control on the page with the same ValidationGroup value. Also consider adding an InitialValue="" onto the TextBox control.
<asp:ValidationSummary ID="vs1" ShowMessageBox="true" ShowSummary="false" DisplayMode="List" runat="server" ValidationGroup="Form" HeaderText="There were problems with your submission:" />
<asp:TextBox runat="server" ID="name" Width="120"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvname" ValidationGroup="Form" runat="server" ControlToValidate="name" InitialValue="" ErrorMessage="Name is required" Display="Dynamic" />
<asp:LinkButton ID="lnkSubmit" Text="Submit" OnClick="lnkSubmit_Click" ValidationGroup="Form" runat="server"></asp:LinkButton>
