Hi i have this validation

<asp:TextBox runat="server" ID="txbcantidad" CssClass="borde_txb" Width="45"></asp:TextBox>
<asp:RegularExpressionValidator
EnableClientScript="true"
SetFocusOnError="true"
ID="Regtxbcantidad"
Display="None"
ValidationGroup="valaccion_paso3_tab2"
runat="server"
ControlToValidate="txbcantidad"
ErrorMessage="Debe digitar números en el campo, sin caractéres especiales ni letras." ValidationExpression="^[0-9]*$">
</asp:RegularExpressionValidator>
<cc1:ValidatorCallOutExtender
CssClass="valtooltip"
PopupPosition="TopLeft"
WarningIconImageUrl="~/admin/img_alcalist/ico_alerta_val.gif"
CloseImageUrl="~/admin/img_alcalist/ico_cerrar_val.gif"
ID="Valtxbcantidad"
runat="server"
TargetControlID="Regtxbcantidad"
HighlightCssClass="campofallido" />

the textbox txbcantidad is in radgrid, this is the radbutton that activate the validation

<telerik:RadButton ID="btnaccion2_paso3_tab2" runat="server" Skin="Office2010Blue" CssClass="txt11000" Text="Guardar Cambios" ValidationGroup="valaccion_paso3_tab2" CommandArgument="guardarref" OnCommand="realizaraccion"></telerik:RadButton>

my problem is that even if validation is enabled in the click event, the button causes postback and gets an error.

normal in this situation is that if the validation is enabled the button doesn't postback, how i fix this?

note that this controls are in a file ".ascx", which is called in a page ".aspx" that have one update panel. maybe this helps.

thanks.

Reminder popup ignores snooze values

Hi,

I tried using the scheduler of the latest build version. Everything was fine, but now I'm caught in a strange behaviour of the reminder popup. First I suspected my own code, but then I tried the live demo and found the same problem.

http://demos.telerik.com/aspnet-ajax/scheduler/examples/reminders/defaultcs.aspx

The problem is not existent im my Firefox and latest Opera. It just appears when I'm using IE 8 or 9. I did not try IE7 or lower.

Problem (IE 8 or 9):
When the reminder poped up, I choosed to be notified again in (e.g.) 4 hours. After clicking 'snooze' the dialog vanished. Now I did something else that caused a postback, e.g. clicking on week view. After a few seconds the reminder poped up again. I tried it many times with different remind intervalls, but every time it was ignored and poped up after postbacks within seconds.

I checked the cookies and noticed that the cookie were stored, so no cookie blocking was active. Of course I also tried 'allow every cookie', but with no success.

As I didn't find anyone else facing the same problem, I suspect myself to miss something. Every hint would be very appreciated.

Kind regards
Oliver

How to select the 1st row in grid on page load and bind the second grid

I am doing a task Master-Detail, for this I have taken two grids where I will initially bind a grid view at this point I would like to select the first row and display the corresponding details in the second grid view.

Custom skins in web.config

I have created a custom skin with stylebuilder and generated a dll with the tool provided in http://www.telerik.com/community/forums/aspnet-ajax/style-builder/tool-for-embedding-custom-skins-into-an-assembly.aspx

Then, in web config i have the following:

<add key="Telerik.Skin" value="MySkin"/>

<add key="Telerik.EnableEmbeddedSkins" value="false" />

<add key="Telerik.EnableEmbeddedBaseStylesheet" value="false" />

It's not working... Do i need to specify the EnableEmbeddedskins in each control?

Client side column show/hide and column widths

Hi,

I have a radgrid with several columns without a width setting, and others with a width set (e.g. HeaderStyle-Width="108px").
The table itself has no specific width set (so it just fills the page).

<telerik:RadGrid ID="rgOFR" runat="server" AllowMultiRowSelection="true" AutoGenerateColumns="false"

AllowPaging="true" PageSize="20" AllowFilteringByColumn="true"

onneeddatasource="rgOFR_NeedDataSource" onitemcreated="rgOFR_ItemCreated"

onitemdatabound="rgOFR_ItemDataBound" >

<MasterTableView AllowSorting="true" TableLayout="Fixed" CommandItemDisplay="Bottom">

I need to hide columns on the client side, however this seems to then shuffle the columns along and leave the width in the original position. (Sorry, hard to explain in text!)

e.g.

| Column 1 || Column 2 || Column 3 || Column 4 |

Hide column 2 and you get this:

| Column 1 || Column 3 || Column 4 |

Where I would expect (and require!):

| Column 1 || Column 3 || Column 4 |

Any advice would be appreciated.

Regards,

Ryan

Displaying HTML

Hi - I use the RADEditor to create HTML which is then saved to a database. On extracting the HTML from the database I need to display it as simply as possible in a lightweight control which resembles a textbox with no borders.
Is the simplest way to use the AccessibleRadEditor and if so how do I render it without borders or menus? Or is there a simpler way?Thanks,
Paul

RadSplitter Height expansion

Hi team,

I have been reading some posts trying to find out how to resize RadSplitter and RadPane height and width. I have realized that RadPane has a 400px default height value and when I resize ONLY the window height from smaller than 400px and up to 400px it resizes well but if I resize window height bigger than 400px it stop resizing, why is it happening, how can I resolve it?

Thanks guys,
Beto.
