I solve the problem with those double-click-on-buttons users with javasript, disabling the button and forcing a postback

function enableLoadButton(button)

{

button.disabled = true;

__doPostBack("<%= btnCharge.UniqueID %>");

return;

}

<asp:button id="btnCharge" runat="server" OnClick="btnCharge_Click" OnClientClick="enableLoadButton(this)" />

Its solve the problem for some users, other still have the problem.
I try the different configurations of the time persistens of the files and nothing. In some point the uploaded file dissapear and i get the exception.
This occurs after the file was processed, when the response is created and i dont need to access to it anymore.

Hope u can assist me, ask me if u need more info.

[Solved] Pasting using the PasteStrip button

Every now and then, if a user hits the PasteStript button to paste in to the editor, an alert window shows up saying "Please use Ctrl+V to Paste".

Why would this happen and, more importantly, how do I stop it?

FWIW, the alert looks a bit like a RadAlert except there is no chrome. It most assuredly isn't a standard javascript alert.

Hi, I am wondering if there is any way to trap the Recurrence checkbox checked event client side? It would be wonderful to be able to get the checkbox state client side to do some validation on other data on our form. Thanks.

[Solved] Load fresh data after one full rotation

I am trying to load fresh data after one full rotation of the rotator. After a full cycle completes I'd like to have an event fire to reload new data and there's no event so far as I can see to do this. The data consists of live scores for a sporting event and I'd like to use one full rotation as the trigger to refresh the data. I am using the Live XML example as my basis. Please advise on the best way to accomplish this as there's no event to signal that a rotation is complete. Clearly the rotator must know when a cycle is complete since it can wrap frames. Thank you.

Regards,
George

[Solved] Cannot upgrade to Q3 styled Skins

Hello

Upgraded my project to Q3 RadControls (2011.3 1115) today.
I read the sticky note about the replacement of the skins, however it does not provide me with information on how to "upgrade" the code regarding to non-default skins.
My previous skin Windows7 cannot be loaded, though I copy Telerik.Web.UI.Skins to the \Bin folder and made a reference to that file.
I have the skin set in web.config:

<add key="Telerik.Skin" value="Windows7" />

This doesn't do the trick, I the the error in the first loaded control:
Telerik.Web.UI.RadSplitter with ID='SiteSplitter' was unable to find embedded skin with name 'Windows7'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false

Can't get ItemTemplate to work when databound

Hi.

I am trying to use ItemTemplate when Databoud, but can't get it to work.
The following code gives an error:
DataBinding: 'Telerik.Web.UI.OrgChartGroupItemRenderer' does not contain a property with the name 'name'.

<telerik:RadOrgChart ID="rocUsers" runat="server" DataFieldID="ID" DataFieldParentID="manager"

DataTextField="fullname" DisableDefaultImage="True" GroupColumnCount="2" >

<ItemTemplate>

<strong><%# DataBinder.Eval(Container, "name") %></strong>

</ItemTemplate>

<RenderedFields>

<ItemFields>

<telerik:OrgChartRenderedField DataField="name" Label=":" />

<telerik:OrgChartRenderedField DataField="avdeling_name" Label=":" />

</ItemFields>

</RenderedFields>

</telerik:RadOrgChart>

The following code gives no data, only the label Name: is shown in the boxes.
It is no difference if the RenderedFields are set or not.
It works fine if I use RenderedFields and no ItemTemplate, so the data is avaliable.

<telerik:RadOrgChart ID="rocUsers" runat="server" DataFieldID="ID" DataFieldParentID="manager"

DataTextField="fullname" DisableDefaultImage="True" GroupColumnCount="2" >

<ItemTemplate>

<asp:Image ID="Image1" runat="server" ImageUrl='<%# Bind("name","~/vimages/ownimages/{0}.jpg") %>'

Width="30px" Height="30px" />

Name:

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Fullname") %>'></asp:Label>

<br />

<asp:Label ID="Label2" runat="server" Text='<%# Bind("avdeling_name") %>'></asp:Label>

</ItemTemplate>

<RenderedFields>

<ItemFields>

<telerik:OrgChartRenderedField DataField="name" Label=":" />

<telerik:OrgChartRenderedField DataField="avdeling_name" Label=":" />

</ItemFields>

</RenderedFields>

</telerik:RadOrgChart>
