WPF Datagrid Row Editing “ENDED” event

五迷三道 提交于 2019-11-30 04:33:38
I know that WPF datagrid has "RowEditEnding" event , but I need to fire the event on after the Row has comitted to check if the newly added row is duplicated and merge the duplicated row. My datagrid has "CanUserAddRow" property set to True. I am using EntityObservableCollection that extends ObservableCollection to synchronize my entity with the collection. So, i considered OnCollectionChanged event, but the "InsertItem" event is raise once user click on the new item place holder row, which means the object is still empty and I cant check for duplicate. Is there anyway that I can raise the

WPF Datagrid Multiple Selection without CTRL or Space

 ̄綄美尐妖づ 提交于 2019-11-30 03:32:33
问题 The WPF Datagrid has two selection modes, Single or Extended. The WPF ListView has a third - Multiple. This mode allows you to click and select multiple rows without CTRL or Shift being held down. Anyone know how to do this for the datagrid? 回答1: This is not supported in the DataGrid in the toolkit, and it looks like it won't be supported when the DataGrid is shipped with .NET 4 either. Yet another reason why this control is not ready for production use. I would go with one of these options:

I am new to the WPF ,and i use it to build a point of sale system. I have a DataGrid control in the main window bound to an ObservableCollection of Item , the cashier will enter/scan the items to be sold the default quantity for each item is 1 but it is available for the cashier to change the quantity manually. Whenever I change the quantity, it should update the total price with the sum of the items' prices when I leave the cell to another cell on the row, but it doesn't happen, the source is updated only when I go to another row not another cell in the same row. Is there anyway to force the

Disable DataGrid current cell border in FullRow selection mode

独自空忆成欢 提交于 2019-11-30 01:44:05
I am using a DataGrid in row selection mode (i.e., SelectionUnit="FullRow" ). I simply want to remove the border that is being placed around the current cell when the user highlights a row in order to have true full row selection (and no cell level selection). I don't mind the notion of the grid maintaining the current cell, I just want to remove that pesky current cell border, perhaps by changing the style of the current cell. What is the easiest way to do this? You could set the BorderThickness for DataGridCell to 0 <DataGrid ... SelectionUnit="FullRow"> <DataGrid.CellStyle> <Style

How do I fix “Two-way binding requires Path or XPath” exception in WPF Datagrids?

问题 Background/context for this question: I have a WPF desktop application. It uses LINQ to SQL to connect to its SQL database, and it displays its data in WPF Datagrids. It was working fairly well, but performance was a problem because LINQ can be deadly slow, so I have been switching my logic and UI controls away from LINQ database contexts as much as possible, and instead loading them into local variables which are very similar to the LINQ objects, which massively improves performance.

How Do I Hide wpf datagrid row selector

感情迁移 提交于 2019-11-30 01:05:29
I'm using the WPF DataGrid control to show some details and a select button, and I don't need the gray selector column down the left-hand side. It's also ruining the beauty of my design. Is there a way to remove it, or how can I style it to match if not? Use the RowHeaderWidth property: <my:DataGrid RowHeaderWidth="0" AutoGenerateColumns="False" Name="dataGrid1" /> Note that you can also specify a style or template for it also, should you decide you really do like it and want to keep it because you can do something cool with it.

How can I disable editing cells in a WPF Datagrid?

余生长醉 提交于 2019-11-29 23:25:12
I'm constructing a datagrid in Windows Presentation Foundation, and I have a problem. When a user double-clicks on a cell in my datagrid, the cell goes into edit mode. I want to prevent that. Instead I want users to be able to select the full row - not edit values in it. How can I make it so that double-clicks select the full row instead of putting the clicked-on cell in edit mode? Leslie Davies The WPF DataGrid has an IsReadOnly property that you can set to True to ensure that users cannot edit your DataGrid 's cells. You can also set this value for individual columns in your DataGrid as
