Editing Data Records with RadGrid in Grid / Outlook Grid

hi there, I'm a newbie to Telerik and I was wondering if it was possible to enable editing of the child items on the RadGrid when it is grouped using Outlook style grouping. Please note that I will disable the ability for the user to drag and drop the column headers onto the main bar header.

Thanks.

Calendar date picker opens in the right bottom of the page on GridDateTimeColumn

Hello, I'm running ASP.NET AJAX grid 2011.1.519.40 with 4 GridDateTimeColumn fields. I'm using auto-generated edit form in popup mode. Whenever the popup screen is displayed, I see 4 date fields with the date picker icon to open the calendar. Whenever I click on one of the date pickers, the calendar comes up fine. However, if I try to click on date picker for the second time in another record after I have already opened and closed the first date picker in the first record, the calendar opens at the right bottom of the page. If I refresh the page (F5) then I can start over, meaning: first record OK, second record opens the calendar at the right bottom of the page again.

What seems to be the problem?

Bug: Exceptions thrown by RadFilter on operations with zero operands

RadFilter doesn't seem to like IsNull, NotIsNull, IsEmpty, and NotIsEmpty.

I've tried this with both RadFilterTextFieldEditor and RadFilterNumericFieldEditor field editors.

Also, you can observe this problem on your own demos -- the page doesn't diplay the error, but got to a dummy page that says: "Sorry, we couldn't find the page you're looking for."

Grid Export to PDF - Straight to Print

I am unable to find out how to go straight to print from a grid pdf export. I am able to do this with standard pdf generation, but I need the file name. I want to click a print button and directly be prompted to print the exported pdf.

Frame1.Attributes("src") = "http://pdfserver.server/Test" & Request.QueryString("id") & ".pdf"

RadComboBox Error from Example

Hi I am trying to run the example shown here:

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multicolumncombo/defaultcs.aspx

I get the following error on this line: public partial class DefaultCS : System.Web.UI.Page

Error 1 Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl). D:\...\RadControlsWebSite1\RadControlsWebSite1\DefaultCS.aspx.cs 12 33 D:\...\RadControlsWebSite1\

CS

namespace Telerik.ComboboxExamplesCS.MultiColumnCombo

{

public partial class DefaultCS : System.Web.UI.Page

{

Should I be changing something else? I am pretty sure I followed all of the isolation steps.

Thanks

RadFilterDropDownEditor problem

Hi,

I found some samples about RadFilterDropDownEditor like:

public class RadFilterDropDownEditor : RadFilterDataFieldEditor

{

protected override void CopySettings(RadFilterDataFieldEditor baseEditor)

{

base.CopySettings(baseEditor);

var editor = baseEditor as RadFilterDropDownEditor;

if (editor != null)

{

DataSourceID = editor.DataSourceID;

DataTextField = editor.DataTextField;

DataValueField = editor.DataValueField;

}

public override System.Collections.ArrayList ExtractValues()

{

ArrayList list = new ArrayList();

list.Add(_combo.SelectedValue);

return list;

}

public override void InitializeEditor(System.Web.UI.Control container)

{

_combo = new RadComboBox();

_combo.DataTextField = DataTextField;

_combo.DataValueField = DataValueField;

_combo.DataSourceID = DataSourceID;

container.Controls.Add(_combo);

}

public override void SetEditorValues(System.Collections.ArrayList values)

{

if (values != null && values.Count > 0)

{

if (values[0] == null)

return;

var item = _combo.FindItemByValue(values[0].ToString());

if (item != null)

item.Selected = true;

}

public string DataTextField

{

get

{

return (string)ViewState["DataTextField"] ?? string.Empty;

}

set

{

ViewState["DataTextField"] = value;

}

public string DataValueField

{

get

{

return (string)ViewState["DataValueField"] ?? string.Empty;

}

set

{

ViewState["DataValueField"] = value;

}

public string DataSourceID

{

get

{

return (string)ViewState["DataSourceID"] ?? string.Empty;

}

set

{

ViewState["DataSourceID"] = value;

}

private RadComboBox _combo;

}

But I faced 2 problems.
1-When I try to set its DataType to System.Int32, I receive "Input string was not in a correct format." error. But when I set it to System.String it works. (the result is = '1' -within single quotas- as expected as it is set to be string). I have checked DataTextField and DataValueField properties and they are referencing to proper fields and datatypes.

2-When I set its value from combobox and add another condition/expression it looses it value and select first value of the combobox.

Any thoughts?

Thanks in advance.

Microsoft JScript runtime error: '' is undefined, client on-load event

Hi:

I am getting:
Microsoft JScript runtime error: 'onLoadAmount' is undefined
error.

<telerik:RadNumericTextBox ID="overAmountTextBox" Runat="server" MaxLength="13"

MaxValue="999999.999999" MinValue="-999999.999999" Text='<%# Bind("overAmount") %>'

TabIndex="7">

<ClientEvents OnLoad="onLoadAmount" />

<FocusedStyle HorizontalAlign="Right" />

<EnabledStyle HorizontalAlign="Right" />

<NumberFormat DecimalDigits="4" />

</telerik:RadNumericTextBox>

<script type="text/javascript">

//<![CDATA[

//

function onLoadAmount(sender, args) {

alert('Amount');

}

//]]>

</script>

The RadNumericTextBox is in a FormView control, when I get the error. If I extract the code and place it on a simple page it finds the on load event.

Hi,

Is there a way to detect a double-click on the title icon on the left side? Our users are expecting to close the window by double clicking on it as they would do in a Windows application.

Thanks.
