Add or remove an attribute from RadTextBox client-side

I'm doing some work in a javascript function and part of it is to remove (or add) an attribute from a RadTextBox. Looking at the list of properties and methods on the Client Object page, I don't see how to do this. I've seen forum posts reference the _textboxelement property of RadTextBox control like so:

<script type="text/javascript">

function setToolTip() {

var RadTextBox = $find("<%= RadTextBox1.ClientID %>"); // Get the textbox client object

RadTextBox._textBoxElement.title = "Changed Tooltip";

}

</script>

I was wondering if this would work. If so, how?

I'm trying to add or remove the data-bind attribute on a textbox.

Thanks.

RadComboBox validation not Working

Hi,
I have an application with some telerik:RadComboBox and asp:RequiredFieldValidator to validate empty value. But it's not working and it's not validating. I checked the radscript manager and I have an error (Error Creating Control).

I had the application with NET Framework 2.0 and I changed to NET Framework 3.5. I have instaled Telerik ASP NET Q1 2010

Is it compatible that version of telerik with .NET framework 3.5?
What does the problem with combobox validation?

this si my html:

<telerik:RadComboBox ID="lstCountry" runat="server" AutoPostBack="True"
onselectedindexchanged="lstCountry_SelectedIndexChanged" SkinID="DropDownList"
TabIndex="17" Width="240px" >
</telerik:RadComboBox>
<asp:RequiredFieldValidator ID="rfvCountry" runat="server"
ControlToValidate="lstCountry" ErrorMessage="Country is required" InitialValue=""
SkinID="RequiredFieldValidator" ValidationGroup="vgpSave" Text="*">
</asp:RequiredFieldValidator>

Regards

Jose

Border disappears on RadWindow...

When I try to open a radwindow, the border is disappearing...If I use similar code on another page, it works just fine...

See attached image, here is the javascript code:

function ShowEditForm(id, boxid, rowIndex, authToken, apiKey) {

var grid = $find("<%= radgrid.ClientID %>");

        var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();
        grid.get_masterTableView().selectItem(rowControl, true);

var url = 'EditReportPage.aspx?id=' + id + '&boxid=' + boxid + '&authtoken=' + authToken + '&apikey=' + apiKey;

        var wnd = window.radopen(url, "EditReportDueDateData");
        wnd.setSize(550, 300);
        wnd.set_visibleStatusbar(false);
        wnd.center();
        return false;
}

4/13/2012 UPDATE:
This seems to be happening on IE9. I hit the page from IE8 and it seems to be working. With that being said, I have another page with a popup radwindow and it appears just fine using IE9. I am having this problem just on one page.

Thanks

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

Hi,

I am creating a custom control in C#. this control will have a radcomboBox and lable in a html table. When you select an item in the radcomboBox, the selected item text will be diplayed in the lable. But when I try to render, I am getting error.

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

RadComboBox

currencySelector = new RadComboBox();
currencySelector.ID = "dsfdsf";
//currencySelector.Items.Add(new Telerik.Web.UI.RadComboBoxItem("Australian"));
htmltableCell.Controls.Add(currencySelector);
htmlTableRow.Cells.Add(htmltableCell);
.....
currencyConverterTable.Rows.Add(htmlTableRow)
currencyConverterTable.RenderControl(output);

What am I doing wrong here???

Thanks,

Toby

GridButtonColumn empty after click

Hi, i added a GridButtonColumn to my grid in the Page_Load event:

GridButtonColumn colEdit = new GridButtonColumn();
colEdit.UniqueName = "Edit";
colEdit.HeaderText = "Edit";
colEdit.Text = "Edit";
RadGrid1.MasterTableView.Columns.Add(colEdit);

When i click on it, i handle the RadGrid1_ItemCommand event:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
if (e.CommandName == "Edit")
...
...
}

After the event the GridButtonColumn is empty, why?
Other problem is that the e.CommandName is alway empty, why?

Easy? Filter button images don't show

I have a page with a RadGrid that works PERFECT! Only problem is the CSS for the grid seems to hide the filter buttons unless the window is maximized - anyway around this?
