RadCombo box and required field validator - why check input text and not value?

The required field validator for radcombobox seems to activate only when the selected item has no text. Shouldn't it be activating when the selected item has no value instead? If I want to set some default text in the combo box, such as "Please choose a value", like the example below, what do I have to do to to make the required field validator activate when the first item is chosen? (Value = "" Text ="Please choose a value"

<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"

SkinID="DropDownList" TabIndex="17" Width="240px">

<Items>

<telerik:RadComboBoxItem Value="" Text="Please choose a value" />

<telerik:RadComboBoxItem Value="value2" Text="item2" />

<telerik:RadComboBoxItem Value="value3" Text="item3" />

</Items>

</telerik:RadComboBox>

<asp:RequiredFieldValidator ID="rfvCountry" runat="server" ControlToValidate="RadComboBox1"

ErrorMessage="Country is required" SkinID="RequiredFieldValidator">

</asp:RequiredFieldValidator>

"Please choose a value"

MarkFirstMatch and Web20 Skin

Hello,

When MarkFirstMatch is set to false, the web 20 skin renders the input box as all blue, whereas when MarkFirstMatch is true, it renders an input box as white. Out of curiosity, why is that, and what specific skin sets the whole input area to a blue gradient?

Thanks.

RadGrid frozen column scrolling issue in FireFox and RTL mode

Hi,
I was using a RadGrid while enabling its freezing columns width RTL direction. All thing works OK, except that i found horizontal scroll does not work for frozen columns in FireFox (When direction is RTL).

Since my essential skills are at client side, so I checked some client side scripts of RadGrid, and, I found issue happens by below js function:

"Telerik.Web.UI.GridScrolling.prototype.onGridFrozenScroll"
in line: x = Math.floor(c.scrollLeft / r * 100);

c.scrollLeft has a negative value on FireFox, when RadGrid is in RTL direction.

For now, I overwrote this function and wrapped c.scrollLeft width Math.abs function. and now it works OK.
I was using RadControl for Asp.Net Ajax Q3 2011.

Gauge options

I know that the Gauge is a brand new offering to the ASP.NET controls collection. I am working on an ASP.NET web application to mimic a similar Windows client using the Telerik WPF controls. Obviously the WPF controls have a great number more options for display. I was wondering if there are any ideas from anyone on how to implement some of these control options using the ASP.NET controls?

In particular are the bezel color around the different radial controls, including the semi-circle and quadrant style radial gauges. The back ground when set shows a square background for radial gauges. Is there anyway for this background to be a circle instead of a square? Any expectations of more control to the Gauge controls in the near future?

Thanks,

James

[Solved] Event from controls in the Grid are not firing.

Let's say I have the following Grid.

<telerik:RadGrid runat="server" ID="MyGrid"

<MasterTableView

<Columns

<telerik:GridTemplateColumn UniqueName="DDLCol" HeaderText="PSO Standard Setting"

<ItemTemplate

<asp:DropDownList runat="server" AutoPostBack="True" ID="DDL" OnSelectedIndexChanged="DDL_SelectedIndexChanged"

/>

</ItemTemplate

</telerik:GridTemplateColumn

</Columns

</MasterTableView

</telerik:RadGrid>

with the following Handler.

Protected Sub DDL_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)

'Do Some stuff here.

End Sub

Execution never reaches this event handler. What am I missing, or how could I better solve this problem?

I've also tried attaching the handler in the ItemDataBound event, but this also has not worked.

Private Sub MyGrid_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles MyGrid.ItemDataBound

If TypeOf (e.Item) Is GridDataItem Then

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

Dim DDL As DropDownList = item.FindControl("DDL")

'databind the drop down list (this works fine of course)

AddHandler DDL.SelectedIndexChanged, AddressOf DDL_SelectedIndexChanged

End If

End Sub

We have a problem with exporting numbers from GridHyperLinkColumn to Excel (Biff). They do get transferred to Excel but are stored as Text.
How can I make sure the values are converted to numbers (column.DataType is Int32)?

Thanks,
