我有存储过程sp_ItemFilter,但问题是当我在文本框中插入数据时,我按btnButton发送数据,未显示在gridview中变空,我该怎么解决这个问题? 使用的代码。
Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Cmd = New SqlCommand("sp_codefilter", Cnn)
Cmd.CommandType = CommandType.StoredProcedure
With Cmd.Parameters
.Add("@codigo", SqlDbType.VarChar, 6).Value = TextBox1.Text
Cnn.Open()
Try
Dim dv As New DataView
Da = New SqlDataAdapter(Cmd)
Ds = New DataSet
GridView1.DataSource = Ds.Tables()
GridView1.DataBind()
Catch ex As Exception
MsgBox(ex.Message)
Finally
Cnn.Close()
End Try
End With
End Sub
End Class

试试这个
Da = New SqlDataAdapter(Cmd)
Ds = New DataSet //<---- this DataSet is empty and needs filling
Da.Fill(Ds); //<------- You need to fill the DataSet here
GridView1.DataSource = Ds.Tables(0)
GridView1.DataBind()

您需要填充数据集,设置select命令,并将特定表绑定到GridView:
Dim Cmd As New SqlCommand("sp_codefilter", Cnn)
Cmd.CommandType = CommandType.StoredProcedure
With Cmd.Parameters
.Add("@codigo", SqlDbType.VarChar, 6).Value = TextBox1.Text
End With
Cnn.Open()
Try
Dim dv As New DataView
Da = New SqlDataAdapter()
Ds = New DataSet
Da.SelectCommand = Cmd
Da.Fill(ds, "MyTable");
GridView1.DataSource = Ds.Tables("MyTable")
GridView1.DataBind()
Catch ex As Exception
MsgBox(ex.Message)
Finally
Cnn.Close()
End Try
