Questions on UI for ASP.NET AJAX Forum

Hello, I am hoping that someone can come to my rescue with this issue. I have been tearing my hair out and just cannot figure out a solution.... I want a ListView that displays images stored in SQL. I have a Stored Procedure that returns the data, including a Thumbnail Image that should be displayed. The data type of the Thumbnail Image is varbinary(MAX). Locally, it works perfectly. However, once I publish to the server, it doesn't. I have three items to display, each with a picture. The first time, the page loads, it will display image 1, but not image 2 and 3. If I click Refresh, it will display Image 2 and 3, but not Image 1. If I click Refresh again, it will display Image 2, but not Image 1 and 3, etc, etc, etc. I used the code found here: http://demos.telerik.com/aspnet-ajax/binaryimage/examples/default/defaultvb.aspx?product=listview to create my page. I even created a blank page, no master page, no tables, no style, etc and literally just copied in the code, changed the DataSource, and the Field Names. Locally = Perfect. Server=Same issue. I'm really at a loss here and would love any insight.... please, please, please, save my forehead from further bruising!

Export Radgrid to excel

Good afternoon guys,

Before I export my grid to excel I have following logic:

Telerik.Web.UI.GridExcelBuilder.

RowElement row = new Telerik.Web.UI.GridExcelBuilder.RowElement();

Telerik.Web.UI.GridExcelBuilder.

CellElement cell = new Telerik.Web.UI.GridExcelBuilder.CellElement();

cell.Data.DataItem =

"NYC";

cell.StyleValue =

"MyHeaderStyle";

cell.MergeAcross = e.Row.Cells.Count - 1;

row.Cells.Add(cell);

e.Worksheet.Table.Rows.Insert(0, row);

And then I style this header:

Telerik.Web.UI.GridExcelBuilder.

StyleElement myStyleH = new Telerik.Web.UI.GridExcelBuilder.StyleElement("MyHeaderStyle");

myStyleH.FontStyle.Size = 25;

myStyleH.FontStyle.Bold =

true;

System.Drawing.

Color col = System.Drawing.ColorTranslator.FromHtml("#2C78FF");

myStyleH.FontStyle.Color = col;

myStyleH.AlignmentElement.HorizontalAlignment = Telerik.Web.UI.GridExcelBuilder.

HorizontalAlignmentType.Center;

e.Styles.Add(myStyleH);

My question is:I need colored "NYC" header like this:
"N" - with the green color
"Y" - with the orange color
"C" - with the blue color.
How can I do that?

Thanks so much for your help.

Appointments in wrong time slots

Hello,

Since update 2012.2.607 we have a problem with our RadScheduler (before we had 2012.1.411).

We have 3 slots for appointments (ex: 08:00, 08:30, 09:00), since the update our appointments all show up in the first column, before they would show up in the correct time slot.

Thank you.

Grid / ListView/DataList View with Grouping

Hi,
I am trying to use RadGrid as ListView layout and was able to follow the demo below to achieve the results.

Grid / ListView/DataList View:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/listview/defaultcs.aspx

Now, I need to be able to use "Grouping" [using ContactTitle:] so that all the ListView items are shown under corresponding Grouping.
Is it possible and if so how?

Thanks for your help.

RadDateTimePicker in layout template firing InitInsert command

Hi,

I would like the RadDateTimePicker located in LayoutTemplate to fire InitInsert command.
The problem is, RadDateTimePicker does not have CommandName property (and CommandArguments), so the only way to do that would be to fire command from SelectedDateChanged.

I understand that RadListViewDataItem can use FireCommandEvent method, but how to get RadListViewDataItem when the RadListVIew is empty?

In other words, how to make the following to start working as intended above

protected void myDatePicker_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)

{

RadListViewDataItem r = new RadListViewDataItem(myRadListView, 0);

r.FireCommandEvent("InitInsert", String.Empty);

}

Thanks,
Jacek

AutoCorrect DatePicker 2012 Q2

Hello,

1) Has there been any change in the autocorrect DatePicker? Is there anyway to disable this functionnality? If my client types in 2012-13-02 I don't want the date to become 2012-02-13 cause maybe he mistakenly wanted to type 2012-12-02.

2)When I type an invalid date like "qwerty", how can I keep the value in the datePicker after a postback. The field does show an exclamation mark but I would like to handle the error myself.

Thank you!

EditCommandColumn - events not firing correctly

Hello everyone,
I need some help.

I'm using the RadGrid Control like this demo with this googlelikefilter. Now I want to be able to edit/insert/delete rows in the RadGrid.
If the EditMode is set to "EditForms" it's working perfect. But when I set the EditMode to "InPlace" the EditCommandColumn is not showing.
So I created an EditCommandColumn on PageLoad. The problem is now that the events are not firing correctly; I always get an exception:

"Sys.WebForms.PageRequestManagerServerErrorException: An error occurred because a control with the ID ctl00 $ ContentPlaceHolder1 $ StundenRadGrid $ ctl00 $ ctl02 $ ctl04 $ Perform Insert Button could not be found, or because the same is assigned ID after postback another control. If the ID is not assigned, you should avoid this error, set the ID property of controls that cause postback events explicitly."

Can somebody help me please?
Thanks in advance,
Esmi
