推荐答案

CommandName值

删除"-删除当前记录.引发RowDeleting和RowDeleted事件.



另请参见:

从网格视图中动态删除行 [ ^ ]

CommandName Value

"Delete" - Deletes the current record. Raises the RowDeleting and RowDeleted events.

如果您将DataTable用作GridView的数据源，请尝试此操作..

首先在DataTable中删除一行，然后再次绑定gridView.

if you are using DataTable as DataSource for a GridView then try this..

Delete a row in DataTable First Then Bind the gridView again.

DataTable dt = (DataTable)(GridView1.DataSource);
dt.Rows.RemoveAt(GridView1.Rows.Count - 1);
dt.AcceptChanges();
GridView1.DataSource = dt;
GridView1.DataBind();

此代码将删除GirdView最后添加的新行.如果要删除任何其他索引的行，则将GridView1.Rows.Count - 1替换为索引值.

希望对您有所帮助.

this code will delete the new row added at the last of a GirdView. If you want to delete row of any other index then replace GridView1.Rows.Count - 1 with your index value.

hope it helps..

Dim RowIndex As Integer = gvRow.RowIndex
        If ViewState("CurrentTable") IsNot Nothing Then
            dt = DirectCast(ViewState("CurrentTable"), DataTable)
            If dt.Rows.Count > 1 Then
                If gvRow.RowIndex < dt.Rows.Count - 1 Then
                    'Remove the Selected Row data
                    dt.Rows.Remove(dt.Rows(RowIndex))
                End If
            End If
            'store the current data in ViewState for future reference                
            ViewState("CurrentTable") = dt
            Session("DS") = dt
            'rebind the GridView for the updated data
            dgv.DataSource = dt
            dgv.DataBind()
            For i = 0 To dgv.Rows.Count - 1
                dgv.Rows(i).Cells(0).Text = i + 1
            Next i
        End If
