The ValidatorCalloutExtender is failing to display the CSS correctly

After successfully customizing the style of my ValidatorCalloutExtender on a RequiredFieldValidator to a more 'Modern UI', I encountered an issue when deploying it to the production server. Despite testing it on multiple browsers with satisfactory results, the CSS did not render correctly in the live environment.

View the Example Image here

Below is the CSS code I used:


.validatorCalloutHighlight 
{
border:solid;
border-color: #FFCC00;
}
.ajax__validatorcallout_popup_table
{
min-width: 350px;
min-height: 40px;
background: #FFCC00;
-webkit-border-radius: 0px;
-moz-border-radius: 0px;
border-radius: 0px;
margin-left:250px;
margin-top:-20px;
color:black;
}
...

The corresponding ASP code snippet:

<asp:TextBox ID="txtUsername" runat="server" Width="300px"></asp:TextBox>
<asp:RequiredFieldValidator CssClass="validator_callout" ID="reqvalUsername" runat="server" ControlToValidate="txtUsername" Display="None" ErrorMessage="Enter a new login name" ValidationGroup="Submit">*</asp:RequiredFieldValidator>
<cc1:ValidatorCalloutExtender ID="reqvalUsername_ValidatorCalloutExtender" runat="server" CloseImageUrl="~/Images/Buttons/cancel_Validator.png" HighlightCssClass="validatorCalloutHighlight" TargetControlID="reqvalUsername" PopupPosition="TopRight" WarningIconImageUrl="~/Images/Status/clear.png">
</cc1:ValidatorCalloutExtender>

I tried various troubleshooting methods including modifying the web.config file but to no avail. If anyone has insights or solutions to this problem, please share as I am determined to implement this new style correctly.

Answer №1

After countless attempts to tweak the CSS with no success in changing the default LemonChiffon notification, I stumbled upon a hidden gem on the depths of the internet. The post found at proved to be the key I was searching for.

The CSS provided in the post completely transformed the appearance of the ValidatorCalloutExtender, giving me the desired result.

.CustomValidator {position:relative;margin-left:-80px;}    
.CustomValidator div {border:solid 1px Black;background-color:LemonChiffon; position:relative;}    
.CustomValidator td {border:solid 1px Black;background-color:LemonChiffon;}    
.CustomValidator .ajax__validatorcallout_popup_table {display:none;border:none;background-color:transparent;padding:0px;}    
.CustomValidator .ajax__validatorcallout_popup_table_row {vertical-align:top;height:100%;background-color:transparent;padding:0px;}    
.CustomValidator .ajax__validatorcallout_callout_cell {width:20px;height:100%;text-align:right;vertical-align:top;border:none;background-color:transparent;padding:0px;}    
.CustomValidator .ajax__validatorcallout_callout_table {height:100%;border:none;background-color:transparent;padding:0px;}    
.CustomValidator .ajax__validatorcallout_callout_table_row {background-color:transparent;padding:0px;}    
.CustomValidator .ajax__validatorcallout_callout_arrow_cell {padding:8px 0px 0px 0px;text-align:right;vertical-align:top;font-size:1px;border:none;background-color:transparent;}    
.CustomValidator .ajax__validatorcallout_callout_arrow_cell .ajax__validatorcallout_innerdiv {font-size:1px;position:relative;left:1px;border-bottom:none;border-right:none;border-left:none;width:15px;background-color:transparent;padding:0px;}    
.CustomValidator .ajax__validatorcallout_callout_arrow_cell .ajax__validatorcallout_innerdiv div {height:1px;overflow:hidden;border-top:none;border-bottom:none;border-right:none;padding:0px;margin-left:auto;}    
.CustomValidator .ajax__validatorcallout_error_message_cell {font-family:Verdana;font-size:10px;padding:5px;border-right:none;border-left:none;width:100%;}    
.CustomValidator .ajax__validatorcallout_icon_cell {width:20px;padding:5px;border-right:none;}    
.CustomValidator .ajax__validatorcallout_close_button_cell {vertical-align:top;padding:0px;text-align:right;border-left:none;}    
.CustomValidator .ajax__validatorcallout_close_button_cell .ajax__validatorcallout_innerdiv {border:none;text-align:center;width:10px;padding:2px;cursor:pointer;}
