RadGridView add new item UI is not pupulating automatically

Hi,

I am using RadGridview for CURD operation. I am using observable collection of custom class where I have data.

For oprtation I am using 2 column say update and delete to push data back to DB. With the property NewRowPosition, adding of new row is coming on top.

When I am adding new row and provided data to all cell and coming out from that row being added focus is going into existing row and new row is getting added in last of collection. that is OK.

My problem is when I have added a row the new row add label should be come but its not. and also I have observed that AddingNewDataItem is not firing as result all logic for the cell that I need to perform is not working. I have used celledittemplate in POC as well.

Please suggest how I can achieved this behavior as soon as possible.

Delete item with DEL key

Hi,

I want to achieve that the user can delete the selected item with the DEL key. I have set the 'CanUserDeleteRows' property to true but when I press the DEL key on a selected Item the Deleting, Delete and the KeyDown event aren't fired. I don't want a additional column with delete buttons or a Delete Button beside of the GridView.

Any idea? My search wasn't successfull....

RadGridView Find Selection Background Color

I have not customised the selection background color of the RadGridView. Nor do I need to. I just need to programatically find out what the selection background color of the grid actually is.

Edit appointment dialog

Is there a method to make the edit appointment dialog completely custom? If this is not possible is there a way to force the schedule view to refresh after an appointment has been edited out side of the dialog shown? We have tried to set the EditDialogStyle to a custom template but it does not give us the desired results it displays the exact same as before.

Thanks!

Missing Localization Entries for FilterRow Mode and Boolean Column

It seems there are some missing entries in the default localization (at least for the german localization) for the grid in the FilterRow mode and a boolean column for languages other than english.

The filter popup shows "True" and "False", though everything else is correctly localized.

The solution was to add the entries 'GridViewFilterIsFalse' and 'GridViewFilterIsTrue' to the localization resource, maybe this is a help for someone else with the same problem.

see:

http://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-localize-the-filtering-ui.html and

[Solved] ToolTipService.GetToolTip Value is Null Exception

Hi everyone,

in the attached file you see the exception I get (Sorry, it's in German). The Problem with this exception is, that it appears not every time by doing the same steps. So we can't say definititly what step let this exception occures.

So here are the circumstances:

RadGradView with some columns (4-5)
Binding on a DataTable
ReadOnly = false

So when from a dialog a value is puttin' in one of the cells, the problem somtimes appears.

I downloaded the source code and searched a bit. (In GridView_WPF.sln: GridView/Cells/GridViewCell.cs)

In the method 'PrepareCellToolTip' the second time when ToolTipService.GetToolTip is called:

var visualElementToolTip = ToolTipService.GetToolTip(this);

var isCellErrorToolTip = this.CellErrorMessage != null && this.CellErrorMessage == visualElementToolTip;

var row = this.ParentRow as GridViewRow;

var rowToolTip = ToolTipService.GetToolTip(row) ?? string.Empty;

Before row is hand over to 'GetToolTip()', there should be proved if it isn't null, right?
