asp.net 使用单个按钮单击清除多个网格的行选择

Question

嗨，朋友们，我创建了一个带有多个网格视图的单一 asp.net 页面（c#）来显示记录。我有多个命令按钮来显示这些网格中的记录。 我正在使用单个按钮来清除网格中的行选择，但它不起作用。 请帮帮我...

 protected void btnClearGridSelection_Click(object sender, EventArgs e)
 {
 if (GridView1.Visible == true)
 {
 GridView1.SelectedIndex = -1;
 }
 if (GridView1.Visible == true)
 {
 GridViewSearch.SelectedIndex = -1;
 }
 if (GridView1.Visible == true)
 {
 GridViewState.SelectedIndex = -1;
 }
 if (GridView1.Visible == true)
 {
 GridViewDistrict.SelectedIndex = -1;
 }
 if (GridView1.Visible == true)
 {
 GridViewType.SelectedIndex = -1;
 }
 if (GridView1.Visible == true)
 {
 GridViewEmployee.SelectedIndex = -1;
 }

 }

//----------用新问题更新我的问题---------- 现在我可以从行中清除选择但面临新问题......当我点击显示（以显示结果状态）按钮时，它正在显示结果并在点击清除选择时清除选择按钮没有问题....但是当我单击另一个显示按钮（以显示结果区）来显示结果时，它正在显示结果，但是当我选择行并单击清除选择按钮时，它同时显示了带有记录的网格。 .....请帮助我在使用区域网格时单击清除选择按钮时如何隐藏状态网格......我正在发布我在按钮单击上使用的代码......

.......清除选择....按钮点击：

 GridViewEmployee.Visible = false;
 btnClearGridSelection.Visible = true;
 string d2 = ddlState.Text;
 string strquery = "select * from  tblAsset2 where v_State=@d2";
 if (con.State != ConnectionState.Closed)
 {
 con.Close();
 }
 con.Open();
 try
 {
 SqlCommand cmd = new SqlCommand(strquery, con);
 cmd.Parameters.AddWithValue("@d2", d2);
 SqlDataAdapter da = new SqlDataAdapter(cmd);
 DataSet ds = new DataSet();
 da.Fill(ds);
 GridViewState.DataSource = ds;
 GridViewState.DataBind();
 int rowCount = GridViewState.Rows.Count;
 if (rowCount <= 0)

我解决了我的问题，它可能对其他人有帮助，所以我发布了它。我写错了一行：- GridViewState.Visible = true; // 我已经注释了这一行并且错误消失了

 protected void GridViewState_RowCreated(object sender, GridViewRowEventArgs e)
 {
 GridViewState.Visible = true; // i have commented this line and error gone

 }
