Question

我想在网格视图内点击按钮时disable gridview行。所以为此，我写了下面的代码。

protected void btnPayGenInvoice_Click(object sender, EventArgs e)
{
    if (strMode == "M")
    {
        Button btn = (Button)sender;
        GridViewRow row = (GridViewRow)btn.Parent.Parent;
        row.Enabled = false;
    }
}

但我收到错误

无法将'Obout.Grid.GridTemplate'类型的对象强制转换为'System.Web.UI.WebControls.GridViewRow'。

请告诉我这里有什么问题

更新

在第GridViewRow row = (GridViewRow)btn.Parent.Parent;行

获取错误

按钮点击事件的代码。

protected void GetRowDataPay(object sender, CommandEventArgs e)
{
    int rowIndex = int.Parse(e.CommandArgument.ToString());

    Hashtable dataItemPay = GridPayInfo.Rows[rowIndex].ToHashtable() as Hashtable;

    if (ObjPriCon.State != ConnectionState.Open)
    {
        ObjPriCon.Open();
        OracleCommand cmdMkeyPay = new OracleCommand("select XXCUS.XXACL_LAND_PURC_INV_VIEW_MKEY.nextval from dual", ObjPriCon);
        string MkeyPay = Convert.ToString(cmdMkeyPay.ExecuteOracleScalar());

        OracleCommand cmdORGID = new OracleCommand("select XXCUS.XXACL_LAND_PURC_INV_VIEW_MKEY.nextval from dual", ObjPriCon);
        string ORG_IDKEY = CF.ExecuteScaler2("select ORGANIZATION_ID,ORGANIZATION_NAME from apps.xxacl_company_mst where ORGANIZATION_NAME = '" + txtCompName.Value + "'");

        string strExpQuery = "insert into XXCUS.XXACL_LAND_PURC_INVOICE_VIEW (MKEY,REF_PURCHASE_ID,REF_SR_NO, " +
                         "REF_PURHCASE_TYPE,ORG_ID,PROJECT_ID,TALUKA_ID,VILLAGE_ID,SURVEY_AREA_7_12,DOC_NO,INVOICE_ID,INVOICE_NUM,VENDOR_ID, " +

                         "'" + Request.QueryString["userid"].ToString() + "', " + "NULL" + "," + "NULL" + ")";
        OracleCommand cmdQuery = new OracleCommand(strExpQuery, ObjPriCon);
        cmdQuery.ExecuteNonQuery();
        ObjPriCon.Close();
        ScriptManager.RegisterStartupScript(this, this.GetType(), "Success", "alert('Payment Invoice inserted into table successfully');", true);
    }
}

你应该使用rowIndex值来获取gridviewrow，然后禁用它像这样

if (GridPayInfo.Rows[rowIndex] != null) 
{ 
  GridPayInfo.Rows[rowIndex].Enabled = false; 
}

无法将类型为'Obout.Grid.GridTemplate'的对象强制转换为'System.Web.UI.WebControls.GridViewRow'。没有解决
