How to display background colour on RadNumericTextBox and RadGrid cell after a value is entered?

I am using RadControls for ASP.NET AJAX Q1 2012 in my current project.

I have a web page which has a RadNumericTextBox and a RadGrid.

The RadGrid has In Place edit mode and only accepts double value on each cell.

I need to do the following on the web page :
1. After the user enters a value on the RadNumericTextBox, display a background colour on the RadNumericTextBox depending on the value entered.
2. After the user enters a value on each RadGrid cell, display a background colour on the RadNumericTextBox depending on the value entered.

The background colour needs to be displayed as soon as the value has been completely entered.

Can you please help me how to do this?

Thanks,
Herman

RadGrid Filtering Nullable ENUMS

I had a problem that I just could not understand why it would not work.
I use enums at times to populate dropdowns. For an example

[DataContract]
[Serializable]

public enum Corporate
{
[EnumMember] [Description("FD")] COMPANY,
[EnumMember] [Description("IB")] INDUSTRY,
[EnumMember] [Description("KD")] PRIVATE,
[EnumMember] [Description("SLE")] SLEIPNER
}

I want Company, Private etc to be populated in the dropdown and then get the description value back.
Well, this has nothing to do with Telerik so far. My problem was when in my datacontract I was using nullable
and wanted to use filter in my RadGrid. It would not work. I debugged my could and
found that the FilterExpression was set to "([Corporate] = INDUSTRY)". Now, this is just plain wrong.
It should be "([Corporate] = 'INDUSTRY')". Note the single quotation marks.

I fixed this issue by adding DataType="System.String" and then the filtering looked ok, but nope
it still did not work.

Why did it not work?

Well, it turned out that when I was using

[DataMember]
public Corporate Corporate { get; set; }

in my contract it works, but when using a nullable property

[DataMember]
public Corporate? Corporate { get; set; }

it did not work.

I fixed it by adding another class called searchcriteria and use that one
for my initial search containing my nullable Corporate and then my original class without nullable
for the filtering. This is very irritating. Can someone at Telerik look into this matter.

Best regards,
Claes

How to set column width to fit, when UseStaticHeaders="false"

Hi,

Title has a typo...
How to set column width to fit, when UseStaticHeaders="true"

I have a RadGrid which likes this:

<telerik:RadGrid ID="CRMGrid" runat="server" AllowSorting="true" GridLines="None" OnSortCommand="CRMGrid_SortCommand" OnItemDataBound="CRMGrid_ItemDataBound" AllowMultiRowSelection="true" OnSelectedIndexChanged="CRMGrid_SelectedIndexChanged" ShowHeader="true">
<HeaderStyle Width="100px" />
<ClientSettings EnableRowHoverStyle="true" EnablePostBackOnRowClick="true">
<Selecting AllowRowSelect="true" />
<Scrolling AllowScroll="True" UseStaticHeaders="true" FrozenColumnsCount="1"/>
</ClientSettings>
<SelectedItemStyle CssClass="SelectedItem" />
<MasterTableView Font-Names="Arial,sans-serif" TableLayout="Auto">
<Columns>
<telerik:GridClientSelectColumn>
<HeaderStyle Width="35" />
<ItemStyle Width="35" />
</telerik:GridClientSelectColumn>
</Columns>
<CommandItemSettings ShowExportToCsvButton="true" />
<HeaderStyle Font-Bold="true"/>
</MasterTableView>
</telerik:RadGrid>

If UseStaticHeaders="true", then header and content are in 2 <div> and 2 <table> tags, table layout is fixed and column width can NOT be fit to max length of cell content. See picture 1.
If UseStaticHeaders="false", then header and content are in same div and table, column width is auto-fit, but header disappears when scroll down.See picture 2.

Any suggestion?
Thanks a lot.

RadTreeList - Reordering Rows

Is it possible to re-order row items via drag-n-drop within a RadTreeList, without using a SQL DataSource? Currently, I bind using a generic list and would like to allow the user to re-order the RadTreeList before saving.

Thanks,
Patrick

How to make the month display for an old date?

I have got a calendar working but when I set the date to an old date (server side) the calendar displays the current month.

I am showing three months in a row. The date assignment during the page onload is working properly.

tclCalendar.SelectedDate = dteDate;

tclCalendar.DataBind();

Ideally the middle month should be the month of the date which I have set.
Is there somthing else which needs setting?

Also, how do I remove the week number column?

<telerik:RadCalendar ID="tclCalendar" runat="server" DayNameFormat="Short"

Skin="Web20" EnableMultiSelect="False" UseRowHeadersAsSelectors="True" UseColumnHeadersAsSelectors="True"

MultiViewColumns="3" AutoPostBack="True" EnableNavigationAnimation="True"

CultureInfo="English (United Kingdom)" ShowOtherMonthsDays="False" TitleStyle-ForeColor="White"

TitleStyle-CssClass="smallButton" WeekendDayStyle-BackColor="#F7F7F0" DayOverStyle-BorderColor="Black"

EnableViewSelector="True">

RadSplitter Height 100%

I have been using the radsplitter and radpanes to manage the layout of a screen in IE9. Everything has been working fine to date with the splitter filling the screen but a couple of my customers have reported problems with the splitter only filling half the page.
I have investigated and it would seem this issue only appears when you run IE7, IE8 or IE9 in compatibility mode.
I essentially have a master page with the following markup:

<form id="form1" runat="server">

<div style="float:right">

<telerik:RadSkinManager ID="radSkinManager" runat="server"></telerik:RadSkinManager>

</div>

<telerik:RadFormDecorator ID="radFormDecorator" runat="server"/>

<telerik:RadNotification ID="radNotification" runat="server"></telerik:RadNotification>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<div>

<div class="pageHeader">HEADER</div>

<div class="pageBody">

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>

</div>

<div class="pageFooter">FOOTER</div>

</div>

</form>

I then have a content page holding the splitter and associated panels as follows:

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<telerik:RadSplitter ID="RadSplitter1" runat="server" Height="100%" Width="100%" >

<telerik:RadPane ID="RadPane1" runat="server">

PANEL1

</telerik:RadPane>

<telerik:RadSplitBar ID="RadSplitBar1" runat="server">

</telerik:RadSplitBar>

<telerik:RadPane ID="RadPane2" runat="server">

<telerik:RadSplitter ID="RadSplitter2" runat="server" Height="100%" Width="100%" Orientation="Horizontal">

<telerik:RadPane ID="RadPane3" runat="server">

PANEL1

</telerik:RadPane>

<telerik:RadSplitBar ID="RadSplitBar2" runat="server">

</telerik:RadSplitBar>

<telerik:RadPane ID="RadPane4" runat="server">

PANEL2

</telerik:RadPane>

</telerik:RadSplitter>

</telerik:RadPane>

</telerik:RadSplitter>

</asp:Content>

The styles used are defined as:

.pageHeader { position:absolute; left:4px; top:4px; right:4px; height:100px; background-color:red }

.pageBody { position:absolute; left:4px; top:108px; right:4px; bottom:108px; background-color:blue }

.pageFooter { position:absolute; left:4px; bottom:4px; right:4px; height:100px; background-color:green }

It would appear the reason for the issue is that the pageBody DIV is held in an absolutely positioned DIV that hasn't had the height set to 100%. Does anybody know how I can resolve this issue?

RadMenu Databind large collection

We use the RadMenu control in one of our user controls.
The page which uses this control render very slow.
After profiling the page with a few tools we came to the conclusion the databinding of the RadMenu takes up 90% of the time spent generating the page.

radMenu.DataSource = collection;

radMenu.DataBind();

The collection has about 1500 items in it. How can we optimize the performance, so the control can cope with such a large number of items in its datasource...

Kind regards,

Menu
