如何将用户输入的值从文本框和组合框绑定到Wpf中的Datagrid [英] How to bind user entered values from textbox and combobox to Datagrid in Wpf

问题描述

如何将用户输入的值从文本框和组合框插入到Datagrid
当我们单击一个按钮时?
在线上是否有示例?显示在ComboBox中. datagrid/listview/任何控件都绑定到ObservableCollection<SomeItemType>.

当用户点击添加按钮时，将使用文本框/组合框中的数据创建一个新的SomeItemType 实例，并将其添加到ObservableCollection<>中.这将自动更新视图(无论您在此处使用什么视图).

希望您知道数据集吗?

if(ans ==是)
{

那么没什么大不了的，只需将文本框或组合框的文本插入到DataSet的某个单元格中即可.

将数据集表分配给DataGrid.DataSource

}
其他

只需发送一条消息，我就会用DataSet的实例来回复您

Is there any example online?

解决方案

Typically, you bind the TextBox to a string variable and the ComboBox selected item to a varable of the type of item displayed in the ComboBox. The datagrid/listview/whatever control is bound to an ObservableCollection<SomeItemType>.

When the user hits an Add button, a new SomeItemType instance is created using the data from the textbox/combobox, and is added to the ObservableCollection<>. This will automatically update the view (whatever it is that you use there).

hope u know the DataSets?

if(ans==Yes)
{

then its not a big deal, just insert the text of textbox or combobox in some cell of DataSet

Assign the DataSet Table to DataGrid.DataSource

}
else
