CustomValidator

I have try to use CustomValidator with telerik:RadTextBox but it is not fired?

<telerik:RadTextBox ID="rtbTelefon" MaxLength="50" Width="220px" EmptyMessage="Telefon" ToolTip="Telefon" runat="server" /><telerik:RadTextBox ID="rtbEpost" MaxLength="50" Width="230px" EmptyMessage="E-postadress" ToolTip="E-postadress" runat="server" /> <asp:CustomValidatorid="AtLeastOneContact" ClientValidationFunction="AtLeastOne_ClientValidate"Display="None" ErrorMessage="Telefon <b>eller</b> e-post krävs!" SetFocusOnError="True"runat="server" />

And in telerik:RadScriptBlock

function AtLeastOne_ClientValidate(source, args) {

if (document.getElementById("<%= rtbTelefon.ClientID %>").value == "" &&

document.getElementById("<%= rtbEpost.ClientID %>").value == "") {

args.IsValid = false;

}

else {

args.IsValid = true;

}

Nothing happand, but if i change to <asp:TextBox it works??
Why does it not work with telerik:RadTextBox?

Initiating an Excel Export from RadGrid

I have got the Export settings enabled within my RadGrid, but cannot figure out how to execute or initiate an export of the data that is currently in the Grid.

<telerik:RadGrid ID="RadGrid2" runat="server" AllowAutomaticInserts="True" AllowAutomaticUpdates="True" DataSourceID="OpenAccessLinqDataSource1" Skin="Sunset" CellSpacing="-1" GridLines="Both" AutoGenerateEditColumn="True" AllowFilteringByColumn="True" AllowSorting="True" ShowGroupPanel="True">
<ExportSettings ExportOnlyData="True" FileName="SystemCabCommExport">
<Excel Format="ExcelML" />
</ExportSettings>

How do you go about creating a button or link to execute the enabled Export Settings?

Export to Ical using a single button

Hi,

The examples I have seen have a button-per-appointment approach. I am interested in exporting all appointments via one button click and preferably, that button is a button that is not integrated into the scheduler, but is a simple .net button elsewhere on the page. Has anyone done this/know if it can be done? Thanks!

Virtual Scrolling using ObjectDataSource

Is it possible to get Virtual Scrolling going using ObjectDataSource? I haven't been able to find any good examples except for those on the demo-site (http://demos.telerik.com/aspnet-ajax/dropdownlist/examples/functionality/virtualscrolling/defaultcs.aspx). Unfortunately, the DropDownList doesn't seem to provide the ObjectDataSource with values for "StartIndex" and "ItemsCount" as per the WebService-datasource example.

Below is a simple example, describing the desired scenario. The Facade is in place and works well with other types of solutions, e.g. paging a Grid using an ObjectDataSource.

<asp:ObjectDataSource ID="ODSNotifications" runat="server"

TypeName="NotificationsFacade"

SelectMethod="Get"

OnSelecting="ODSNotifications_Selecting"

EnablePaging="true"

SelectCountMethod="GetCount"

StartRowIndexParameterName="StartIndex"

MaximumRowsParameterName="ItemsCount">

<SelectParameters>

<asp:Parameter Name="userId" Type="Int32" />

<asp:Parameter Name="fromDate" Type="DateTime" />

</SelectParameters>

</asp:ObjectDataSource>

<telerik:RadDropDownList ID="RDDLNotifications" runat="server"

DataSourceID="ODSNotifications"

CssClass="RDDLNotifications"

DataValueField="Title"

DataTextField="Id"

OnItemDataBound="RDDLNotifications_ItemDataBound"

DropDownWidth="200px"

DropDownHeight="100px"

EnableVirtualScrolling="true">

<ItemTemplate>

<asp:Panel ID="PNotification" runat="server" CssClass="w_n_outer" onclick="StopPropagation(event);">

<div class="w_n_inner">

<asp:Label ID="LType" runat="server" Font-Size="0.8em" />

<br />

<asp:Label ID="LTitle" runat="server" Font-Bold="true" />

<br />

<asp:Label ID="LBody" runat="server" />

</div>

</asp:Panel>

</ItemTemplate>

</telerik:RadDropDownList>

Any help would be greatly appreciated!

Why is it there?

Also, how do you format the text and title?

Thanks.

Multiple Files Uploaded in Click Order as oppose to Alphabetic Order

Have an AsyncUpload control with MultipleFileSelection set to Automatic. User can upload multiple images which are previewed in a listview and user can remove or reorder the images before final save.

Seems the AsyncUpload control uploads the files in alphabetic order as oppose to the order that the user has clicked.
Is there any setting or way to make the upload of the files in the order that the user has clicked using Ctrl Mouse Click?

Thanks

Glenn

Display Network Folder

I am looking for a solution that will allow me to click a button or a hyperlink within a row and open a folder on our network. The location to be opened is stored in the record source for that grid.

I have tried a couple of things, both of which failed. Granted, the solution I have are either my own creation or a hybrid of my code and assistance from the forums.

FAILED SOLUTION #1
This column contains a button that opens the folder. This does work locally, but does not work when published to our web folder.

<telerik:GridButtonColumn FilterControlAltText="Filter Files column" CommandName="ShowFiles" UniqueName="Files" ButtonType="PushButton" HeaderText="Files" Exportable="False" Text="Display">

</telerik:GridButtonColumn>

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

Dim value As String

If e.CommandName = "ShowFiles" Then

Dim dataItm As GridDataItem = TryCast(e.Item, GridDataItem)

value = dataItm("Location").Text & "\03 Submitted\"

Process.Start("explorer.exe", value)

End If

End Sub

FAILED SOLUTION #2
This does nothing but reload the page.

<telerik:GridTemplateColumn UniqueName="LinkColumn">

<ItemTemplate>

<asp:LinkButton runat="server" ID="LinkButton1" CommandName="ShowFiles"></asp:LinkButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

Private Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = TryCast(e.Item, GridDataItem)

Dim row As DataRow = TryCast(item.DataItem, DataRowView).Row

Dim linkButton As LinkButton = TryCast(item("Location").FindControl("LinkButton1"), LinkButton)

linkButton.Text = "Location"

linkButton.PostBackUrl = "#"

End If

End Sub

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

Dim value As String

If e.CommandName = "ShowFiles" Then

Dim linkButton As LinkButton = TryCast(e.CommandSource, LinkButton)

Dim dataItm As GridDataItem = TryCast(e.Item, GridDataItem)

value = dataItm("Location").Text & "\03 Submitted\"

Process.Start("explorer.exe", value)

End If

End Sub

Rad menu opens again if cursor moved anywhere near to the menu.

Hi ,

I am using Rad Menu.
When I hover my cursor over the rad menu, it opens- which is an expected behaviour.
When I remove my cursor from it, it gets closed- which is also an expected behaviour.
Now when I remove my cursor from it and try to move near the area of menu before it is closed completely, it opens again - Which is not expected.

I have one button beneath the Menu, when I open the menu and think that I dont want to use menu but click the button instead,
I cannot use it within that fraction of second, I need to wait till the menu gets closed completely., otherwise it will open itself again.
Which is quite cumbersome for the user, especially when my Menu list is quite long.

Can any one please suggest how to solve this issue.

Thanks in advance...!!

Scheduler Appointment move issue

Hi,

I have a problem with the appointment move in the asp.net scheduler. Sometimes when i move the appointment to another slot, it doesn´t stay there. In some machines it never works in some months like (november and december 2014). It happens in all views (month, week, day...). I debbugged the app and when the problem happens it doesn´t show any erros in the pageMethod that update the appointment date. I need a solution for this issue.

Asp.net framework: 3.5
Telerik Version: 2013.1.417.35

Thanks
