[Solved] RadButton doesn't fire CustomValidator

Hi,
I've a Checkbox, with a custom validator:

<asp:CheckBox ID="Datenschutz" runat="server" />

<asp:CustomValidator ClientValidationFunction="ValidateDatenschutz" runat="server" ID="DatenschutzValidator" CssClass="..." ErrorMessage="<br/>..." />

The RadButton is here:

<telerik:RadButton ID="Submit" runat="server" Text="Speichern" OnClick="OnSubmitClick" CausesValidation="true" />

The JavaScript validation looks like this:

function ValidateDatenschutz(sender, eventArgs) {

eventArgs.IsValid = document.all[datenschutzCheckboxId].checked;

}

(datenschutzCheckboxId is defined)
Clicking on the button in IE calls the validation function. Firefox, however, does not.

Is this a known problem, or did I make a mistake?

Thank you
René

[Solved] update grid

Hi,

I'm using the update feature of the grid. during the update, I use the

OnItemDataBoundHander(object sender, GridItemEventArgs e)

to prepopulate the RadComboBox as instructed within the examples. the following contains the C# code

if (e.Item.IsInEditMode)

{

GridEditableItem item = (GridEditableItem)e.Item;

if (!(e.Item is IGridInsertItem))

{

//this area is for update

using (dl = new WellVentDataLayer())

{

//For the Area section

RadComboBox combo = (RadComboBox)item.FindControl("RadComboBoxArea");

RadComboBoxItem selectedItem = new RadComboBoxItem();

selectedItem.Text = ((DataRowView)e.Item.DataItem)["AreaName"].ToString();

combo.Items.Add(selectedItem);

selectedItem.DataBind();

}

}

and the following aspx code

<telerik:GridTemplateColumn UniqueName="AreaName" HeaderText="Area"

SortExpression="AreaName" ItemStyle-Width="150px" DataField="_AreaName"

AndCurrentFilterFunction="Contains">

Template footer

</FooterTemplate>

<%

#DataBinder.Eval(Container.DataItem, "_AreaName")%>

</ItemTemplate>

<telerik:RadComboBox runat="server" ID="RadComboBoxArea" EnableLoadOnDemand="True" DataTextField="AreaName" OnItemsRequested="RadComboBoxArea_ItemsRequested" DataValueField="ID" AutoPostBack="true" HighlightTemplatedItems="true" Height="140px" Width="100px" DropDownWidth="200px"

OnSelectedIndexChanged="ComboBox1_OnSelectedIndexChangedHandler">

<%# DataBinder.Eval(Container, "Text")%>

</ItemTemplate>

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

the code gave the following error on the row

Unable to cast object of type 'GHG_MCA.WellVentEvents' to type 'System.Data.DataRowView'.

selectedItem.Text = ((DataRowView)e.Item.DataItem)["AreaName"].ToString();

thanks,

excelml export number format

I have a grid with a column that is bound to a text field. This text is usually a number, but is sometimes a "-" character.

When exporting to Excel, I would like for the numbers to display with a single digit after the decimal point. So integers are displayed as #.0... (100.0 for example). I have the following style declaration:

Dim pctStyle As New Telerik.Web.UI.GridExcelBuilder.StyleElement("PctStyle")

pctStyle.AlignmentElement.HorizontalAlignment = GridExcelBuilder.HorizontalAlignmentType.Right

pctStyle.NumberFormat.FormatType = GridExcelBuilder.NumberFormatType.GeneralNumber

pctStyle.NumberFormat.Attributes("ss:Format") = "0.0"

It doesn't seem to work. The exported Excel file always shows 100 as 100, not 100.0.

I am wondering if this is because the underlying grid column data field is text? Is there any way to format the numeric output of a grid column that isn't bound to a numeric field?

I want to create a RadComboBox using javascript and add it to the div. Is it possible to create it dynamically at client site?

radComboBox.id = "RadCBox" + ID;
AddItemsToComboBox(radComboBox, orders);

var divTag = document.getElementById("dynID");
divTag.appendChild(radComboBox);

}

Thanks,
