我的问题是,是否有办法对数据集的记录进行过滤,并利用这些记录填写数据网格。 例如,一份数据表(有3栏:StudentName,>Gender)填满了学生名单。 i 有两个数据网,其形式为:DatagridView1和Datagridview2。 F 。
在我目前的解决方案中,我正在使用一种 lo。
For each iStud as datarow in iDataset.Tables(0).Rows
IF iStud.Item("Gender").ToString = "M" Then
add this record to DatagridView1
Else
add this record to DatagridView2
End If
Next
是否有办法不使用 lo?
是的。 你们都需要做的是使用<代码>SlectT过滤数据。
例如,
。
DatagridView1.Datasource = xSet.Tables("StudentList").SELECT("Gender = M ")
DatagridView2.Datasource = xSet.Tables("StudentList").SELECT("Gender = F ")
简要解释:
xSet is the name of the Dataset
StudentList is the name of the Datatable
Gender is the name of the Column where you want to filter
