Hey at Telerik

Untill i upgraded to Q1 2011 i was hooking the event VScrollBar.VisibleChanged on the RadTreeView in order to correctly place another control relative to the offset it gives when the vertical scollbar shows.

What am i supposed to hook the change on now ?

Sincerly

Export To CSV - Decimal places

Hi,
I am trying to set the decimal places in the export to be a customizable setting. I am using the following lines of code

col.ExcelExportType =

DisplayFormatType.Currency

col.ExcelExportFormatString = GetDecimalFormat()

WHere the GetDecimalFormat would return "{0:#.##} for 2 decimal places.

But this snipet does not work. It renders on the csv witht the same number of decimal places as in the data. Are there similar properties for csv as there are for excel?

Thanks
Deepak

Cant add time in GridDateTimeColumn?

Hi guys,

this may sound stupid but how do you add edit the time in a GridDateTimeColumn in the grid view? Everytime i click on the column, the text box shows only the date component e.g.[ Thursday, 1 April 2011 ] which is fine but I would also like to be able to edit the time in the column... clicking on the dropdownbutton in the editor calls up the calendar but that only allows me to change the dates.

Please Advise.

Thanks

gridviewcolumngroup headers wrapping text

The gridviewcolumngroupheaders are wrapping texts. While this is ideal, it does not expose a property or method to show tool or screen tips with the full text on mouse over. In the attached image, (Q1) - Spontaneous Awareness - is actually (Q1) - Spontaneous Awareness - First Mention

Thanks

RadGridView - save changes to a rows data back to database

Hi there

I'm trying to achieve row-level validation and saving. The validation is working OK and and I can reject invalid user-input at the row level.

However I'm a bit lost as to how which event to use to catch the fact a row has changed so I can then call dataset.savechanges().

I've tried -
RowsChanged event but it fires when the grid is first populated with data
RowValidated event but it fires AFTER I leave the row that was updated
RowValidating event which is nearly there but it isn't until it's finished that I can detect changes in my dataset using datatable.getchanges()

The basic point is that i'd like remove the need for a Save button that will save ALL changes to the data in the grid. The reason for this is that the database has lots of users and I want to maintain concurrency. If I can get the database record to change when a ROW is updated then there is less chance of concurrency issues.

Thanks in advance

Unable to add column names to child/parent template in Hier. Grid

Hi,

I am getting an error throw when I try to add the column names to the child and parent relations in a hierarchical gridview. I am using your WINForms sample, except that I changed the datasource to Entity Framework 4 .edmx, and am using .Net 4.0 on a WIN7 OS. I've attached 2 files, 'Form1' shows the results. All works fine, except the child grids are not linked to the ContactID on the grid (the relationships are defines properly in the .edmx). 'Relations' shows the results I'm getting when I try to set them in the properties window.

Thanks

Steve
