GridHyperLinkColumn - Retrieve email address in code behind

Hi! Could someone help me with getting the value of an email address in a GridHyperLinkColumn from the code behind please?

Here's the aspx code:

<telerik:GridHyperLinkColumn DataNavigateUrlFields="Email1" UniqueName="Email1"

DataNavigateUrlFormatString="mailto:{0}" DataTextField="Name" HeaderText="Reviewer" SortExpression="Email1"

ShowFilterIcon="false" ShowSortIcon="false" AutoPostBackOnFilter="true" />

Essentially when a user clicks on a submit button for the RadGrid itself, I would like to grab the email address for each selected row in the grid and send an automated email.

Here's the code behind I have for finding the selected rows in the grid, however, I'm not sure how to retrieve the value of the email address from the GridHyperLinkColumn...

If (RadGrid1.SelectedItems.Count > 0) Then

For Each item As GridDataItem In RadGrid1.SelectedItems

'Add code here to retrieve email address

Next

End If

Any help would be greatly appreciated. Thanks!

Dropdown portion of CSS

I've been looking at the RadMenu Base styles and trying to figure out exactly which portion of the CSS is what makes the dropdowns work.

I built my own RadMenu.css but for some reason the dropdown's always appear at the top left portion of the screen.

Below please find my css, any clues as to what is missing would be much appreciated. Or just point me to an example dropdown css code for the RadMenu.

.RadMenu_ArtDebutant

{

width:100%;

}

.RadMenu_ArtDebutant > ul.rmRootGroup

{

float: left;

display: block;

list-style-type: none;

font-size: 17px;

text-transform: lowercase;

font-family: Arial Baltic, Arial;

}

.RadMenu_ArtDebutant > ul.rmRootGroup > li.rmItem

{

float: left;

width: 254px;

height: 30px;

background-color: #333333;

border-right: 1px solid #939393;

margin-right: 1px;

}

.RadMenu_ArtDebutant > ul.rmRootGroup > li.rmLast

{

margin-right: 0px;

width: 255px;

}

.RadMenu_ArtDebutant > ul.rmRootGroup > li.rmSeparator

{

width: 1px;

float:left;

height: 30px;

background-color: White;

border: 0;

}

.RadMenu_ArtDebutant > ul.rmRootGroup > li.rmItem > a

{

color: White;

text-decoration: none;

height: 30px;

vertical-align: middle;

display: table-cell;

padding-left: 15px;

width: 253px;

}

.RadMenu_ArtDebutant > ul.rmRootGroup > li:hover

{

/* background-color: #415353; */

}

.RadMenu_ArtDebutant > ul.rmRootGroup > li.rmItem > a.rmFocused

{

background-color: #415353;

width: 254px;

}

/* drop down. Some stuff from menu.css base styles */

.RadMenu div.rmSlide

{

position:absolute;

overflow:hidden;

display:none;

float:left;

width: 254px;

background-color: #333333;

opacity: 0.5;

-moz-opacity: 0.5;

}

.RadMenu ul.rmVertical

{

float: left;

display: block;

list-style-type: none;

font-size: 17px;

text-transform: lowercase;

font-family: Arial Baltic, Arial;

}

.RadMenu ul.rmVertical > li.rmItem

{

clear:both;

width: 100%;

text-decoration:none;

margin-left: 20px;

}

/* drop down portion end */

How to disable other controls when particular input fails a RadInput RegEx or Validation Setting?

Hello,
I'm having an issue with the input validations available in the RadInputManager where I need to prevent the user from entering data in other form fields when there is an error in a particular form input field due to the nature of the application. I have code that will disable the input controls, but I cannot find a way to determine is control X is valid.

What I really need is a client side method to determine if the input field is valid or not in my scenario, but cannot seem to find a way to accomplish that using the OnValidating event. In my scenario, I need to dynamically add input validation settings via the page's codebehind (e.g. not through clientside script) and cannot allow the user to add data to other fields while one field is invalid.

User enters invalid text in TextBox1
Validation message appears
All other input controls other than Textbox1 should be disabled
When the user enters a valid value in Textbox1 that passes the validation then all the other input boxes should be re-enabled (Note: This is the step I cannot determine how to accomplish)

In the code below if the line RegExSetting.ClientEvents.OnValidating = "OnClientValidating" is commented out then the user can enter values in any textbox or input field, which is not desired while Textbox1 has an invalid value.

If there was a way to tell if Control X was valid when the control loses focus that would solve the problem (in my actual scenario 100% of the controls are dynamic so I cannot hardcode control names) as I could execute code that re-enables all the controls if Control X is valid.

ASPX:

<telerik:RadAjaxManager ID="AjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Area">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Area" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="RadInputManager1" />

<telerik:AjaxUpdatedControl ControlID="Button1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadInputManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Area" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default" MinDisplayTime="2000">

</telerik:RadAjaxLoadingPanel>

<telerik:RadCodeBlock ID="CodeBlock" runat="server">

<script type="text/javascript" language="javascript">

function OnClientValidating(sender, args) {

var inputId = args.get_input().get_id();

if (inputId != null)

{

var inputs = document.getElementsByTagName('input');

for (element in inputs)

{

inputs[element].disabled = true;

}

document.getElementById(inputId).disabled = false;

}

function OnClientBlur(sender, args) {

//How do I tell if the input is valid, e.g. passed RadInputManager validation setting, OnBlur or another clientside event?

}

</script>

</telerik:RadCodeBlock>

<div>

<asp:Panel ID="Area" runat="server">

<asp:PlaceHolder Runat="server" ID="DynamicControls"></asp:PlaceHolder>

</asp:Panel>

<asp:Button ID="Button1" runat="server" Text="Button" />

</div>

New Ideas... :)

Hello,

I'm using a lot the RadScheduler and it's great, but I have some more new ideas for you.

It would be great if it could be possible to:

Select appointments and drag & drop all the selected appointments to a new date (Like this we would be able to drag and drop a lot of appointment in one time)
Select appointments and to delete all of them with one confirmation

This select appointment stuff could be a checkbox witch appears (like the delete) when we hover the appointment.

It would be great if you can look at those features.

Thanks a lot

SplitCell doesn't split the cell

Hello

When i right click a cell in the editor and select "Split Cell" it adds a cell below the current cell instead of splitting the cell..
What "Split Cell" does is exactly what "Insert Row Below" does...
I must have this working correctly..

Any resolve?

Thank you..

Popup Window Icon

Hi,

How do you change the icon for the popup window?

I know how to change it for normal windows but not the spellchecker window.

I'm assuming that some css will be needed?

Best Regards,
