Breaking changes - Q2 GridDropDownColumn

Hi,

I just update a project to AJAX 2011.2.
This added HtmlEncoding to the GridDropDownColumn.
I have several GridDropDownColumns where I build hyperlinks using the following property:

ListTextFormatString="<a href='CustomersEdit.aspx?LIFNR={0}'>{0}</a>"

After updating to Q2 I no longer get hyperlinks - instead I get the plain text.
Searching the forums I fond the "HtmlEncode" property - but this does only exist in "normal" Grid columns - not in GridDropDownColumns.

How can I overcome this issue with Q2?

Thanks in advance
Manfred

Export ExcelML Format date to a culture

Hi

i'm exporting a radgrid and trying to format the date to a culture e.g en-us, en-gb.

i've looked at http://www.telerik.com/help/aspnet-ajax/grid-excelml-export.html

but this only allows me to specify shortdate, general date etc

what i want is to display it in the export as follows

en-us - 8/24/2011
en-gb - 24/8/2011

i have formatted it in the radgrid by setting the culture on the page_load

System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(siteCulture);
RadGrid1.Rebind();

as i understand from http://www.telerik.com/community/forums/aspnet-ajax/grid/exportsettings-api.aspx

The export gets the data from the db and not the radgrid, so the format in the db is shown, is that right?

i am using onNeedDataSource to populate my radgrid

my current code for export cell styles is:

protected void RadGrid1_ExcelMLExportRowCreated(object source, GridExportExcelMLRowCreatedArgs e)

{

e.Row.Cells.GetCellByName("ItemCreatedWhen").StyleValue = "dateStyle";

}

protected void RadGrid1_ExcelMLExportStylesCreated(object source, GridExportExcelMLStyleCreatedArgs e)

{

foreach (StyleElement style in e.Styles)

{

switch (style.Id)

{

case "headerStyle":

style.FontStyle.Bold = true;

break;

case "itemStyle":

style.InteriorStyle.Color = System.Drawing.Color.White;

style.InteriorStyle.Pattern = Telerik.Web.UI.GridExcelBuilder.InteriorPatternType.Solid;

break;

case "alternatingItemStyle":

style.InteriorStyle.Color = System.Drawing.Color.LightBlue;

style.InteriorStyle.Pattern = Telerik.Web.UI.GridExcelBuilder.InteriorPatternType.Solid;

break;

}

StyleElement myStyle = new StyleElement("dateStyle");

myStyle.NumberFormat.FormatType = NumberFormatType.ShortDate;

myStyle.FontStyle.Bold = true;

e.Styles.Add(myStyle);

}

how do i format the date as i want based on culture?

also the background colors i'm applying do not get added to the A column in the excel, why is this?

Thanks

Adam

RadGrid DateTime Columns messed up in Safari 5.1

Hello,

I have a problem with RadGrid's DateTime Columns when the Page using the Grid is displayed in Safari 5.1 (and presumably also other versions of Safari). The Columns are several thousand pixels long.

I am using 2011 Q2 controls for ASP.NET.

I have set up a demonstration page, which includes basically the same Grid as my real web application does, and the error is present there aswell: http://paeppi.com/RadControlsWebApp2/Default.aspx

In Safari, this example looks like this: Screenshot

As you can see, there are basically no custom css styles on the page that might mess up the Grid.

The aspx source is:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="RadControlsWebApp2.Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

{

protected void Page_Load(object sender, EventArgs e)

{

RadGrid1.NeedDataSource += new GridNeedDataSourceEventHandler(RadGrid1_NeedDataSource);

}

void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

using (govistasigsDataContext db = new govistasigsDataContext())

{

RadGrid1.VirtualItemCount = db.Users.Count();

RadGrid1.DataSource = (from p in db.Users select new

{ p.ID, p.RegisterDate, p.LastLogin }).Skip(RadGrid1.PageSize * RadGrid1.CurrentPageIndex).Take(RadGrid1.PageSize).ToArray();

}

I tried fiddling with Safari's developer tools a bit, but to no success so far.

Any help is appreciated.

Best Regards.

RadGridNumericColumn not formatting to 2 decimal digits in the grid view

I am experiencing a problem where i have set the dataformatstring on my radgridnumericcolumn to {0:c} and it is appearing with a bunch of decimal digits rather than just 2 , i have also set the decimal digits property to 2 and tried {0:c2} and allowrounding. When in edit mode it displays how i want to with just 2 decimal places but on the grid itself its displaying with more than 2.

here is an example of what is being used now :

COLUMN :

<telerik:GridNumericColumn DataField="Premium" DecimalDigits="2" DataFormatString="{0:c}" DataType="System.Decimal" ColumnEditorID="PremiumEditor" HeaderText="Premium" UniqueName="Premium" SortExpression="Premium" >

<HeaderStyle HorizontalAlign="Center"></HeaderStyle>

<ItemStyle HorizontalAlign="Left" Font-Names="Verdana" Font-Size="11px"></ItemStyle>

</telerik:GridNumericColumn>

EDITOR:

<telerik:GridNumericColumnEditor ID="PremiumEditor" runat="server">

<NumericTextBox>

<NumberFormat DecimalDigits="2" />

<NumberFormat AllowRounding="true" />

<NumberFormat KeepNotRoundedValue="false" />

</NumericTextBox>

</telerik:GridNumericColumnEditor>

Any idea what might be happening? Again it looks exactly how i want in edit mode but not on the grid itself

The message received from the server could not be parsed

Hi all,

I am using 2011.2.712 version.
I usually (not always) get this error and I have tried to read many articles about the issue on this forum and the others but not successfully.
Here are my 2 scenario :
1. The first page has a RadGrid which is in a RadAjaxPanel. When I interact with its paging (the number, or icon Next, Pre, etc), this error usually appears. I mean it's not always.
2. The second page has a button which used to export data into a folder on hard disk with .csv extension. I have replaced Response.Close(); by HttpContext.Current.ApplicationInstance.CompleteRequest();. It's OK. But after finishing this action, this error appears.

I really don't know how to fix this issue.
Please let me know what is the problem and how can I solve it.

Thanks in advance,
Phuc

Please help to save my energy.

RadTextBox cursor not visible

Hi,
I have a rad text box in a rad window. On page load i simply try to set focus on it using radajaxmanger. It runs successfully on all other browser except for firefox3.6. Focus gets onto the text box as soon as i click on the control. I tried so many ways to set focus on it(client side as well) but it didn't prove any fruitful result. Is it something related to browser behavior or i need to look onto controls. Please help asap.
Thanks in advance.
