WPF DataGridTemplateColumn Visibility Binding under MVVM

由 别来无恙 提交于 2020-01-21 09:03:46
问题 I have a DataGrid bound to an ICollectionView in my ViewModel. The DataGrid is inside a UserControl which is used in a few different data scenarios, some of which require certain DataGrid columns while others don't. I just want to bind the DataGridTemplateColumn's Visibility property to the inner label's Content property so if none of the rows contain a value, it will be hidden. I have a String to Visibility converter set, but can't figure out how to find the inner lable's Content property.

different kinds of cells in the same column

由 ＊爱你＆永不变心＊ 提交于 2020-01-17 11:15:17
问题 I need to render a datagrid with different kinds of cells in the same column. For example, I have a datagrid with a column "name" and a column "value". Depending on the "type" of my record, I would have different cells in the column "value" like a combobox or a simple textfield. and I don't really see how to do that programmatically... I don't know if the datagrid is the best choice. Any hint? I'm using asp.net/vb.net with framework 3.5 回答1: You can do that using the user control, where you

Update WPF DataGrid ItemSource from Another Thread in PowerShell

由 孤人 提交于 2020-01-17 05:08:11
问题 I have datagrid that gets updated when a button is clicked. However in some cases the data is taking 30 seconds+ to return and the Window freezes. I want to be able to get the data and populate the datagrid from another thread so as not to hang the main window. The DataGrid is read only. Eventually want to have a "cancel" button and animation to indicate progress, but for now just want to get this working. I made a sample program that can demonstrate the issue, which was based on http://learn
