I have two examples now, my first two, where a place a RadComboBox on a web form, and populate it, but it won't drop down. I first picked this up on a big web application project, and then on a simple little web site project, for investigating this. In my sample project, it is the only control on the page besides the ScriptManager, and there are rows in the data source, and it does display the first row, but it just doesn't drop down. Any ideas on this?

BTW, this is theh first time I've restored this project onto a new XP machine, where I previously was working on a Vista machine that died.

RadGrid - Add MenuITem to HeaderContextMenu Programmatically

Hi,
I want to add custom menu items to HeaderContextMenu of RadGrid.
I am able to do it from Javascipt OnClientLoad event.

But I want to do this in code behind. I tried following way:

this.HeaderContextMenu.PreRender += HeaderContextMenu_PreRender;
void HeaderContextMenu_PreRender(object sender, EventArgs e)
{
RadMenuItem resetItem = new RadMenuItem("Reset Columns New");
resetItem.PostBack = false;
resetItem.Visible = true;
this.HeaderContextMenu.Items.Insert(2, resetItem);
}

But this doesnt add new menu item. Any idea how I can achieve this?

Hiding the value of a cell without collapsing the column

I have a RadGrid on my page displaying a list of search results from my database. Some of these results have associated files which I provide a download link for, and some don't.

For the results that don't have an associated file I want to hide the link in that row only. I can do that, I've found, using this code in the ItemDataBound event:

if (e.Item is Telerik.Web.UI.GridDataItem)

{

if (!((bool)((DataRowView)e.Item.DataItem).Row["IsElectronic"]))

{

((Telerik.Web.UI.GridDataItem)e.Item)["colDownload"].Visible = false;

}

The problem is that by setting the GridDataItem's Visible property I'm effectively collapsing that column for that row, moving everything out of alignment with the grid headers. Instead, I'd like to do something to empty the contents of the cell, or change just that cell to a different column type, or something similar?

find RadDatePicker within a div

Hi, how do I get a handle to the RadDatePicker, within the context of a div.
my code snippet looks like this:
<div id="div123">
<telerik:RadDatePicker ID="txtSomeDate" runat="server" CausesValidation="True">
</telerik:RadDatePicker>
</div>

The command :
var somedate = $find("<%=txtSomeDate.ClientID %>");
returns me the datepicker.

However, I have a requirement where I need to get a handle to this datepicker which is within the div "div123" only.
This is because I have this datepicker within a user control and this user control could be embedded multiple times in the same page.

I tried $find("<%=txtSomeDate.ClientID %>",div123) but it returns null.

Any clues on how to get this working?

Thanks
Suchitra

extending AsyncUpload control

Hi I want to extend RadAsyncUpload control to meet our
custom validation need. However, I am experiencing two issues here.

1. RadAsyncUpload contains two controls, one is
textbox and other is a button to invoke file explorer. However, to show error
how can I only target the textbox and not the button? Say for example, I want
to change only textbox border color when its invalid (and not the button)

2. In extended control’s PreRender, when I change CssClass attribute of the
control if control is invalid, the change doesn't reflect on the control, but when I change the CssClass attribute before
the condition (if valid), the change takes effect. So looks like I can’t change the style
attribute after first load, which is very strange. However, I am not sure why
this is happening

Hope someone can help me with this.

Thanks

RadComboBox and Screen Readers

I am trying to get a site to work with a free screen reader (NVDA). I am making the fields more accessable by setting the AssociatedControlID of the asp:Labels to the associated fields. This technique works well for RadTextBoxes, but so far, it has not worked (NVDA will not read the label when the focus is on field) for any RadComboBoxes. Here is what the label / RadComboBox combo looks like:

<asp:Label ID="lblPAddrPreStreetDir" runat="server" EnableViewState="False" meta:resourcekey="lblPAddrPreStreetDirResource1" Text="Pre-Street <br>Direction:" AssociatedControlID="ddlPPreStDir"></asp:Label>

<telerik:RadComboBox ID="ddlPPreStDir" runat="server" AutoCompleteMode="SuggestAppend" DropDownStyle="DropDownList" meta:resourcekey="ddlPPreStDirResource1" TabIndex="2" Width="100px" CausesValidation="False" MarkFirstMatch="True">

<Items>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource1" Text="None" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource2" Text="EAST" Value="E" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource3" Text="NORTH" Value="N" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource4" Text="NORTH EAST" Value="NE" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource5" Text="NORTH WEST" Value="NW" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource6" Text="SOUTH" Value="S" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource7" Text="SOUTH EAST" Value="SE" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource8" Text="SOUTH WEST" Value="SW" runat="server"></telerik:RadComboBoxItem>

<telerik:RadComboBoxItem meta:resourcekey="ListItemResource9" Text="WEST" Value="W" runat="server"></telerik:RadComboBoxItem>

</Items>

</telerik:RadComboBox>
